Big sound from a small box

Don't have the space for a big subwoofer enclosure, but still want the thrill of sub-bass? At only 3" deep, Alpine's PWE-S8 powered subwoofer fits in all kinds of tight spaces: in the trunk of your car, behind the seat in your pickup, or even under the seat in some cars. And it's made to stand up to life on the road, with its rugged cast metal enclosure that's built to take the hard knocks of a tight installation while protecting your equipment.

In the box

Alpine PWE-S8 side view

At only 3" deep, the PWE-S8 can fit almost anywhere.

Alpines uses a Class D amplifier rated at 120 watts RMS to drive the PWE-S8's 8" shallow-mount, high-excursion subwoofer, so there's plenty of power for your bass. The amp features controls for phase, gain, and a low-pass crossover, so you''ll be able to match the bass up to the rest of your system.

You'll also find an input for a wired remote control that lets you dial in your sound from the driver's seat. Easy-access RCA line-level inputs and speaker-level inputs with automatic turn-on make it easy to integrate this sub into almost any system. The PWE-S8 has everything you need to bring bass to places where there was never the room for boom.

Thumpy

Dan from El Cajon, CA on 6/6/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

This sub rocks! The twenty year old Alpine head unit in my BMW E30 had seen better days so I replaced it with the ute-62b and the ktp445a 4channel amp, but only have mounting for four 5.25" speakers. Sounds great but with the small speakers it just didn't hit the lows. Then a friend told me about the pwe-s8¡ Installation was super easy. Doesn't quite fit under the seat, but right behind. It fills the sound spectrum and absolutely thumps my little bimmer. Seriously, I was cranking some Pantera on the freeway and thought I had developed a driveline vibration. Turned down the volume to listen and it went away! Seriously enough bass for my car!

Pros: Easy installation, sounds great, compact.

Cons: None

Not worth it

I can feel it with my hand on the unit and that's about it. I can turn the volume knob from all the way down to all the way up and it makes no difference. Used an 8 gauge wiring kit and I have a sony XAV-1000 head unit and I get more bass out of my 6.5" speakers than this sub.

Pros: Looks

Cons: No bass, from a sub...

Small Package Big Punch

Darin from Cape Coral, FL on 5/11/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Great compact sub, good punch in a small package. Crutchfield is awesome, got the amp and suggested "kit" to get it connected. EVERYTHING is in the power kit, the wire quality is top notch. Take my advice, buy the suggested installation packages offered, you will not be disappointed. Installed the sub woofer in a 1993 Honda Del Sol, behind drivers seat. Incredible sound for any 2 seat car with limited space.

Pros: Compact, easy set up, can use speaker level or RCA input.

Cons: Pricey, but worth it.

Best Value

William from Pacifica, California on 3/20/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

I was bummed about having to use a stock head unit. This little sub, however, when properly wired thumps. Its strong point if correctly installed is flexibility. It just works so well with a factory unit. Impressive tight bass. I listen to Classic Rock and Electronica/Dance (deadmau5-Hooverphonic-Kaskade) This sub and the four new 6x9s Crutchfield recommended simple kick. It hits the lows. It will dim your head lights (I might take that 4ga line power straight to the battery.) Thanks to Crutchfield for supplying me proper install guidance. Installation was easy. Tapped in from the head unit as they recommended and ran Main Power cable, Remote lvl control, speak outs into one bundle. Ran them to the amp located under driver's seat. When using the stock HU, this Alpine PWE-S8 absolutely deserves a Line Out Converter. Don't cheap out and use the high-level outs, just don't! The LOC makes a night and day difference. LOC Installation is just one more small step. Totally satisfied with this unit. Big bass. Use a LOC. It seriously lets this unit perform at another dimension. You'll think you're running way more than what you got. Great Value.

Pros: Clean, tight, focused bass. Hit's way above its class. Easy install

Cons: Power Hungry.

Loved the sound I got out of this unit. For a week, that is. I wanted to test the sound a week after installing, so cranked up my volume. The unit cut out and never came back. Power lights are active, but no sound. Ordered a different brand to replace. Not pleased with Alpine, that's for sure.

Pros: Good sound

Cons: Bad quality

Nice Addition

Well made housing. Install was a chore but that's car electronics. Happy with the output once I had it all installed. It's a compact sub, so that is what your expectation should be prepared for, but I paired with a Pioneer 8200NEX and Alpine S series 6-3/4" speakers and it fills my large volume area van with some rocking, full sound. Pretty well satisfied.

Pros: Solid feel, nice effect, really enhances the listening experience

Awesome under seat solution

Scott from Bay Area, CA on 1/8/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

I put this in a 2006 Tundra Access Cab. It fits under the front passenger seat - but I did have to reroute some of the factory power seat wiring. I removed both driver and passenger front seat, and console - it makes doing a clean install much easier, and you can plan your wire runs - my system has no engine noise issues. The factory system had an amp that was under the rear passenger side bench. I bypassed the factory amp using Crutchfield's awesome wiring diagram, eliminated need to re-wire all the door speakers. Helpful tip: use the all-in one wiring to do the bypass, so much easier and keeps it neat and clean. This sub is just what I wanted - some punch for Classic Rock, Grunge, 90's Rock, etc... not a "thumping system, but gives great sound.

Good, solid under-seat Sub. Fits where others might not.

James from LaGrange, NY on 12/28/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

A good solid under-seat sub. Won't rattle the windows, but its compact, well made and fleshes out the lower end quite well. I found adjusting the crossover to a roughly mid point setting seemed to work best in my application. Test different settings yourself. Better build quality and sound than a less expensive and bulkier Sound Ordnance, which never worked right using my speaker level inputs. Read the directions CAREFULLY. This unit prefers BOTH L and R signals for proper operation.

Pros: Good sound Compact fit Appears well made Good adjustments Independent remote volume control

Cons: Speaker input and power lines on the same multi-pin connector. Would have preferred the two be separate. Fuse a bit bulky

Quality Sound & Construction With A Small Footprint

Douglas from Little Rock, AR on 8/16/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

This powered subwoofer was EXACTLY what I was looking for; a compact option that easily fit under my passenger side front seat, built-in amplifier, and does an excellent job of filling in the lows that my 5.25" woofers cannot touch. As others have mentioned, if you are looking for annoying car shaking bass, this sub isn't for you. The first thing you notice about the Alpine is the weight and rugged construction. It delivers excellent, quality bass in a small package. It does an excellent job of filling in the low end I'm missing from my 5.25" woofers. It I like the Alpine has an in-line fuse, multiple connection options (RCA or tapping the speakers), and an inline volume remote. Admittedly, I didn't think I would use the remote much, but depending on the type of music (rock, R&B, etc) or my mood, I tinker with the volume much more than expected. I had no issues with this product but the only issue I could see for some would be the wiring harness. The wires for the power and ground are relatively short (around 8 inches), which is something you should consider when planning your installation.

Pros: Excellent Job Filling In Lows Compact Quality & Rugged Construction In-Line Fuse Multiple Connection Options (RCA or Speaker) Remote Volume Control

Cons: Wiring Harness (Wire Length ~8")

Better than expected!

Mark L from Columbus, OH on 2/27/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

I was worried that I would not be happy with this purchase, but I was pleasantly surprised by how much of a difference this sub made in my system. My 2005 Accord Coupe has a CDE-124SXM receiver with the KPA-445 amplifier and upgraded Alpine 6x9's in the rear package shelf and the OEM component speakers for the fronts. I installed this sub under the driver's seat. The difference in bass response and depth is significant. This is my first sub and I couldn't be more pleased. I wasn't looking to wake the neighbors (but I am sure I could), so I didn't need any more than this sub delivers. I whole heartily recommend this powered subwoofer.

Pros: Great Sound. Easy Installation.

Cons: Did not completely fit under seat (I had some clearance issues that required that the sub needed to be installed with the long side front to back. Brackets for installation could have been thicker (mine bent/distorted when screwed in). Cable leads could have been longer.

I looked at a lot of powered subs, articles, reviews, and decided on this one based on some of the reviews and the Alpine reputation. What a great decision.

Pros: Size, quality construction, sound

Cons: I would have liked to hear it before buying. It would have made my choice much easier.

This is a great high powered 8" unit. I installed one under the driver seat and one under the passenger seat in my '04 Double Cab Tacoma. They take up virtually no space and are complexly hidden under the seats. Two of these together makes for a solid sub combo.

Pros: Small. High powered. High quality unit enclosure.

Made a huge difference in my 2013 Audi S4

wohoho from Massachusetts on 8/20/2015

Verified customer (What's this?)
Verified employee purchase (What's this?)

When I bought my 2013 S4, it was at the end of the model year and I was unable to get one with the B&O sound system. Although the basic Concert system has 10 speakers, its deficiencies became clearer over time. The free air sub on the rear deck is by far the weakest link. I hate to add one with an enclosure in the trunk that would lose a good part of the luggage space. The PWE-S8 proves to be the perfect choice. The 8" sub may seem small, but the 120W amp and solid aluminum chassis are designed as an integrated unit. make it perform far better than what one might expect from an 8" driver. I can't see ever needing more for listening to music. I see some people who installed this sub and say that it's not doing much, but that could be a defective unit, improper adjustment or bad installation. There is simply no way that this sub would ever have little or no effect on the bass. There are other choices of compact powered subs. I chose this one because I decided on Alpine SPR-60C for the front and rear door replacement after listening and comparing to others under $500/pr. So it's an easy decision to get the Alpine sub. I placed it just behind the passenger's seat on the driver's side. Folding down the seat makes easy access to the adjustments and connections. Otherwise they are out of the way. The factory amp is 40Wx2 for the front pair and 20Wx2 for the rear. Having 120W for the sub is more than enough.

Quality sound

CmG from Washington on 1/27/2015

Verified customer (What's this?)
Verified employee purchase (What's this?)

Installed 2, 1 under drivers and 1 under passengers seat in my 2007 extended cab Nissan Frontier and I'm happy with them. Using an Alpine receiver that already had a nice sound quality to start with and these units were a nice compliment. Best feature in my opinion is the small footprint which allowed for a discreet installation location. Sound quality exceeded my expectations, not extremely powerful but thats not what i was after anyway. I like the build quality as well, heavy construction with nice fit and finish throughout. Installation maybe took half an hour at most.

Pros: Great sounding, heavy construction, extremely simple installation

Cons: Id prefer if the power and ground leads weren't built into the speaker wire harness just to eliminate some wire clutter but could always clip some unused wires to clean things up

I've tried multiple powered subs like this and this one is the best so far. I'm an Alpine guy since the early 80's and I'm glad that Alpine has finally joined the compact sub group. I put this behind the back seat in a 2013 F-150 SuperCrew. It fills out the music nicely. It's not the slam your head into a wall subwoofer but rounds it out and has enough thump to let you know it's there. The higher volume setting will make the mirrors and the seat vibrate but not to the point of it becoming mind numbing. I couldn't be happier.

Pros: size, hookup, Alpine

Cons: none

I didn't expect that this subwoofer would be loud, but I did expect that would improve the sound quality, but it didn't. I have a stock headunit connected to a 4-channel amp that feeds a pair of components and a pair of 2-ways, the adition of the sub didn't make much difference.

Very pleased with this powered sub. I purchased this for my 2010 Ford F-150. It fit perfectly under the rear seat on the passenger side. Build quality of this sub is exceptional. This sub is not cheap, but it also will not disappoint. Install time in my truck was approx 2.5hrs. Sound quality is exceptional if you are looking for fidelity and not to rattle your doors. The sub does include the wired remote. The Crutchfield Overview states the wired remote is an optional assessory... Not the case....Very happy with this purchase

Pros: High quality build, excellent sound/fidelity, fits under the seat of a Ford F-150 ??

Cons: High side of the price range

Crutchfield response on 9/22/2014
We looked into it and Darren is correct: the wired remote is included in the box with the powered sub. We've updated our records and website accordingly.

Features

Auto Turn-on: If using the speaker level input, an automatic circuit turns the amplifier on when it senses an input signal. When using the line level inputs you must also use a remote turn on lead.

Low Pass Filter: The amp has a built-in low-pass filter, variable from 50 to 150 Hz.

Speaker Level Input: A speaker level input harness is included, making it easier to add the amplifier to a factory radio or to a receiver with no preamp outputs.

Wired Remote: Using the included wired remote you can easily adjust the bass output level from the driver's seat (or wherever you mount the remote). The range is 0 to -20 dB, relative to the gain setting on the subwoofer chassis.

Controls:

  • Gain: rotary control; 0.2-4.0 volts line level; 0.5-10 volts speaker level
  • Low Pass Filter: rotary control; 50-150 Hz
  • Phase: two position switch; 0° or 180°
  • Power Mode: two position switch; SP IN (speaker level input, auto sensing) or REM (wired remote turn-on)

Connections:

  • Harness: the included 12" harness contains power (+12 volts), ground, remote turn-on, and speaker level inputs (left and right)
  • RCA: left and right line level inputs
  • Remote: 3.5mm mini-jack for use with the included wired remote

Dimensions:

  • Width: 13.4"
  • Height: 2.875"

Q
Does this have a crossover that will limit the frequency sent to the speakers? i.e. all frequency under say 150hz is handled by the sub then the upper frequencies sent to the speakers?
[ Chris  Jun 25, 2019 ]
1 answer
A
Hello. The controls on this unit are for the sub only. A high pass crossover for your car's speakers will be at your head unit if so equipped with such features. Hope this helps.

Can you wire rear speakers direct to powered sub woofer?

A
I can't answer for sure. I powered my speakers off of a separate AMP
[ Gary  Mar 22, 2019 ]
A
I believe so. Wiring diagram shows wiring to all four speakers though. Also without leads for sub use only you'll have to adjust the gain manually.
[ Robert  Mar 22, 2019 ]
A
Didn't consider trying that. All of the speakers are separate from the subwoofer.
[ PAUL A  Mar 22, 2019 ]
A
I believe the answer is "no." I did not do the installation personally, but I studied the wiring harness & electrical connections. I think any direct connection to another set of speakers would be unconventional and not work.
[ Alan  Mar 22, 2019 ]
Q
Can you use two of these?
[ Tim  Jan 01, 2019 ]
3 answers
A
I suppose you could, but it all depends on the wiring. Each one of these powered subs connects via a pair of RCA cables to a preamp output (and a multiple wire pigtail). And these low-profile subs are a compromise from the start. If I had a system in my car that was so serious that I wanted two subwoofers, I would not be looking at these little powered units. Hope that helps.
[ Alan  Jan 09, 2019 ]
A
I think you can!
[ Carmen  Jan 08, 2019 ]
A
If you are using RCA output, yes you could, you would have to run separate power to both. Would not recommend two if you are using speaker level outputs. You will need a splitter off deck RCA inputs, you will need 4 total.

Would this fit under driver seat of a 2018 sienna?

You need to measure to be sure. It is very compact and puts out excellent bass for the small size. Fits nicely under driver seat of 2014 Nissan Armada.
[ ERIC L  Nov 15, 2018 ]
A
You'll never know until you measure. Height of unit is ~3". LxW dimensions are too large to fit between the anchor points of the seats in my Subaru Outback. BTW, I've been disappointed in the performance. I know it's small and just provides fill, but I thought it would have more kick. My previous powered sub did have that kick, but the sound was fuzzy, not tight.
[ Alan  Nov 15, 2018 ]
A
you have to measure the space under the seat and compare it to the specifications of the unit. - might work better under one of the rear passenger seats
[ johnny  Nov 15, 2018 ]
A
I haven't driven a Sienna in over five years. I would caution putting the sub under the driver seat. Especially if you have powered seat. Look for a better location and the sub will serve you well.

I purchased this sub to go under the seat of a 1973 Jeep CJ5. We had to use some small spacers, but, it fit beautifully and sounds awesome.

There is definitely a way to connect this to the stock radio in your pickup and you can call an advisor on 1-800-324-9695 to get a personal recommendation on the gear that is needed to make it connect to the stock radio. There may be an issue fitting it under the seat. Given the measurements we got, I don't think it will. You might call the advisor while at the truck to double check our measurements and see if it can fit My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101

We do not have the available space dimensions under the seat of your vehicle. We can provide the dimensions of the Alpine enclosure which you can use to cross-reference against the available space you find there: 13-1/2"W x 9"H x 3"D At just 3" thick, you will not need a lot of clearance.

Q
Will this sub fit under the seat of a 2011 Miata?
[ Michelle  Oct 08, 2017 ]
3 answers
A
Based on all of the information I've been able to find on various Miata enthusiast sites, the 3rd gen Miatas don't have enough vertical clearance under the seats for an under-seat subwoofer. Most people mount them on the vertical wall behind the seats instead, at least in earlier Miatas (that's where I have the sub in my 1991).
[ Andrew  Dec 07, 2017 ]
A
I'm afraid we don't have the area under the seats listed in the research for your 2011 Mazda Miata. However, when flat the Alpine PWE-S8 measures 13-1/2"(depth) x 9"(width) x 3"(height)--if you find there's sufficient room under your seats for a box with those dimensions, the Alpine would be a great option. For more details or to discuss further, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!
[ Larry  Oct 11, 2017 ]  Staff
A
I don't know much about the Miatas, but the measurements of the subwoofer are the w 9.5 inches L 13.5 inches and the height 2.75 inches. If this measurements are under the seat it will be a fit. Performance wise I do recommend it.

Does anyone have this in a Subaru hatch back? Anyone listen to death metal ? How's the double bass drum kicks? Also can it handle hip hop bass? I know it's not gonna rock the house. Just wanted to fill in the lows.

A
Installed mine in my gmc 2500 hd behind rear seat. I had to turn my sub settings on head unit to max for great results. I listen to all types of music. Also when I say great results, it's just a "comfortable" bass level. To really bring out low ends I would need two or something bigger.
[ George  May 20, 2017 ]

If you are hooking it to stock radio you need a loc. I haven't heard about hooking it directly to and amp.
[ Ruben  May 06, 2017 ]

It connects to the sub port on the head unit for signal and on-off, and to a 12-v source for power
[ Chris  May 03, 2017 ]

You need to connect it directly to the head unit. It has a built in amp and connecting to an existing amp may damage the unit.
[ Stephen  May 03, 2017 ]

Sorry, the speakers in my 99 Suburban would not support an amp. However the sound is awesome now. Really nice bass sub...
[ JERRY  May 03, 2017 ]
A
I have connected this to a factory head unit using speaker level inputs: it has rca connections for line level, I plan on putting a 50 watt alpine amp on the system in order to keep factory head unit. This amp should pair nicely with the power of this alpine sub- all in a 2016 Prius.
[ MICHAEL  May 03, 2017 ]
A
Sony what? and Kenwood what?
[ JULIO  May 03, 2017 ]
A
It will connect directly to your head unit, provided you have the RED/WHITE output on your head unit. Since it is an amp, it won't connect to another amp.

Q
Does this fit under rav4 2015-17 passenger seat?
[ Steevvee  Jan 18, 2017 ]
3 answers
A
I put mine under a 2005 Honda Accord Coupes seat. The only issue I had was in the length of the unit. I had a heating duct the pushed the unit back so that it extended past the bottom of the seat (just barely). I think the RAV's seat is a bit larger and sits up higher than the Accord's seat, so it should be fine. I would check under the passenger seat to see if there are any obstructions. I also had to place the unit inboard so that the seat adjuster cleared. I had plenty of clearance on the sides, so this was no problem.
[ Mark  Jan 20, 2017 ]
A
I don't know. I don't have a RAV4. Try measuring the space under the seat and checking the dimensions.
[ ROBERT S  Jan 19, 2017 ]
A
I would say most likely yes. I bought one and fit it behind my 2 seater 1985 Nissan 300zx behind the passenger seat and the seat still goes back all the way and reclines all the way back. Great little powered subwoofer. Not huge thump but very good bass sound. You won't be disappointed. Hope this helps you. Randy
