Kenwood KSC-PSW8 reviews
This is a great little sub that really rounds out the audio in my Jeep. I have a 2016 Jeep Wrangler Unlimited and this thing is awesome. It has way more punch and depth than I expected. I cant even turn it up past half way. I had a small 6" sub in my previous Jeep and it was not very loud, so my expectations were very low. I mounted it under the front passenger seat with no issue. The wired remote fits perfectly in the hand brake well. I dont normally write reviews, but I felt like this was way more than I had expected and wanted to share. Just remember, it is an 8" sub. It has great sound, but if you want door rattling, bother every other car around you sound, this is not for you. If you want to really enhance your factory sound, or even your upgraded speakers like mine, this is a worthy addition to any vehicle that doesnt want to sacrifice space for sound. To make installation easier on my Jeep, I did install a PAC-OEM-1 interface so that I could keep my factory head unit and install via RCA Cable instead of splicing into speaker wires. It made the installation super simple, but maybe added a bit of time to the installation since you have to get to the back of the head unit.
Pros: Small Fits under the seat Easy installation Great Sound

Perfect way to round out the sound in my 4 door Tundra. Tired of the weak, muddy factory system I decided to upgrade. Pioneer Bluetooth deck and Alpine component door speakers needed something to bring out the low end in my favorite songs. This Combo Amp/Sub worked perfect. Easy to install, mounted under the driver seat. It gives all the bass feel of a bigger sub, and enough bump to make my hour long commutes more enjoyable. I listen mostly to Rock and Punk, which sounds great, but bumps the Rap/Top 40 the wife and kids like. Inside the cab sounds amazing, without being the annoying bass bumper at stop lights. (I'm 30 something so that's import to me) The thing I like the most about this combo is the thumb dial on the remote. Even for songs in the same genre, the bass levels vary. I like being able to easily change bass levels without taking my eyes off the road. Switching from a bass heavy track to the news station for the latest traffic report, this comes in handy. Mounted under the driver seat, I pulled the remote up between the seat cushion and the center console for easy access. Metal box is solid construction. Perfect for my needs, can't think of anything bad to say about it.
Pros: Thumb dial on remote makes it easy to adjust level for best sound on varying songs on my playlist
Cons: Can't think of any

Good product, just not the thump I was looking for, nor loud enough for my preference.
Pros: Small and easy to connect
Cons: Not loud enough for my liking.

The Kenwood KSC-PSW8 is my first power subwoofer I have ever bought. I put it in a ford F150 super crew cab and it is powerful without taking over the whole back seat. I was trying to install everything myself and finally decide to go in the Harrisonburg store for them to finish everything up. The salesman was even impress with the amount of sound this little sub was putting out. If you want good bass and not lose a lot of space, this is a good pick.

Great companion to the KENWOOD excelon head unit I installed in my 07 Jeep Commander. Great subtle bass, not overpowering.

Great size. Compact and fits well under the passenger seat of my 2008 Grand Caravan. Brought the depth out in my Spotify and MP3s. Dial in the crossover in your head unit and it allows the music to really come through.
Pros: Versatile mounting Enough bass for rock. Plenty of wire
Cons: None so far

I couldn't be happier with this little sub. I originally purchased it to go under the seat in my 2017 Chevy Volt LT (without Bose), but it was just too tight of a fit and I worried about the back seat passenger not having sufficient legroom since the car is pretty small as it is. I ended up mounting it behind the back passenger seat. The sub takes up a pretty small footprint, so it doesn't really impact trunk space. The important part: Sound is far better than what I would have expected from such a small enclosure. The bass is really deep and clear, and can get quite loud if you so choose. I am not one to rattle the teeth of other drivers on the road, which is not what I wanted in the first place. Installation was a bit tricky since Crutchfield does not suggest adding something like this to my vehicle (at the time of this review), so I had to reach out to some Volt specific forums on guidance for what wires I needed to spice into. In the end, I could not be happier. Very glad I decided on this sub.
Pros: - Great Clarity - Pounding Bass - Remote has great control of volume and frequency - Doesn't require Antenna Signal Wire to power on and off
Cons: - None yet

Overview: The Kenwood KSC-PSW8 is an amplified subwoofer with a built-in Class D amplifier. It contains an 8" cone woofer, which is driven by a 150-watt RMS (250W Max) amp. The acoustic suspension (sealed) enclosure is compact enough to fit under the seat, behind the seat, or in small storage compartments. The KSC-PSW8 comes with a wired remote control to let you control its volume, phase, and the frequency of the low-pass filter.
Enclosure: The KSC-PSW8 features a specially designed acoustic suspension enclosure. It includes a 7-1/2" metal mesh grille (non-removable) to protect the woofer.
Wired Control: The active subwoofer comes with a wired remote control with a 16.25' cable. From the control, you can set the volume, and vary the Frequency Control (of the built-in low pass filter) from 50 Hz to 125 Hz. In addition, you can switch the phase of the woofer from 0°(normal) to 180° (reverse), if needed.
Connections: The KSC-PSW8 comes with a single harness with power/ground/turn-on wiring and RCA input connections. The harness has 16.25' lengths of 14-gauge power wire (with an in-line 10A ATO fuse) and 18-gauge turn-on lead, plus a 5' dual 18-gauge ground wire. It also includes a 28" RCA input for connecting the subwoofer to an aftermarket stereo via RCA cables. A 14' speaker input harness is provided for connecting the sub to a factory radio (or a radio without RCA outputs). You can splice it to the head unit's speaker wires and plug it into the RCA input. An RJ-45 jack is provided on the bottom of the subwoofer for plugging in the remote control cable.
Controls: The only controls for the PSW8 are located on the wired remote. The rotary volume control (input sensitivity) lets you match the input of the subwoofer to the output of the head unit, and to control the volume of the sub, relative to the other speakers in the system. The rotary frequency control adjusts the cutoff frequency of the low-pass filter between 50Hz and 125Hz. If you have large main speakers (6x9 or 6-1/2") in the vehicle, you can set the subwoofer's low pass filter near the 50Hz to 80Hz range. If the main speakers are smaller (4" or 5-1/4"), the low pass filter should be set in the 100Hz to 125Hz range.
Installation: The subwoofer comes with the hardware needed for installation. The enclosure installs using two brackets (included) attached on opposite ends. The power, remote, and signal connections are made in a recessed area on the bottom of the unit. The wires exit through a channel on the side of the unit. The included cable clamp holds the power, remote, and signal wires in place as they exit the channel.
