Advanced engineering

The P3SD4-8 8" shallow subwoofer hangs with its bigger brethren, thanks to advanced materials and engineering. Rockford uses anodized aluminum for the cone and dust cap making the woofer light and easier to drive, yet rigid enough to maintain its shape under maximum load. The M-Roll Santoprene™ surround also provides excellent excursion for maximum output while being durable enough to last.

Powerful bass for a tight space

A low-profile frame houses the subwoofer, with abundant venting to battle overheating and thermal breakdown. At 2-5/8 inches deep, this sub will fit into places where no bass has gone before — just build a custom enclosure or find a suitable box. The dual 4-ohm voice coils allow you to wire up multiple subs or to coax optimum performance from your amplifier.

To drive this single subwoofer, we recommend a mono amplifier rated between 120 and 225 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Perfection!! . The sound of my Rockford Fosgate speaker surpasses the JBL speaker that was previously in my 4Runner. I could tell the first minute of hearing sound from that speaker that I had made the right choice. If you love loud music like I do, I highly recommend Rockford. Although my other speakers are sounding just fine I will be replacing them in the near future as I now know what great sound is! Crutchfield is spot on when it comes to professional customer service and shipment practices. Many thanks !!! - I am now back to listening to Alan Jackson music as loud as I want! :) "A happy customer is a repeat customer" I'm a happy customer!

Tight clean bass.

Verified employee purchase (What's this?)

Awesome Product and customer service. Bass is a lot more than what I expected, big difference. Tight with no distortion. 2002 Yukon XL with stock equipment. Now considering upgrading the rest of the door speakers to match up to the subwoofer. So back to Crutchfield for more.

Pros: Great Bass for the $ and sound is clean even with the stock amp.

Cons: None

Great replacement for 2001 Suburban / Yukon XL

Stephen from Carrollton, GA on 6/6/2018

2001 Chevrolet Suburban

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

I purchased this 8" P3 to replace the blown subwoofer in my 2001 Chevy Suburban (also compatible with Yukon XL). After removing the trim ring edges with a Skil jigsaw it fit perfectly in the original enclosure and sounds awesome! It's great to have bass in the car again even if it is still pushed by the factory amp. The process to replace the subwoofer takes 60 - 90 minutes and requires you to cut the trim ring on the Rockford Fosgate speaker. This cutting voids your warranty so be sure you are comfortable with this risk. Ideal Tool Set: Panel tool or metal putty knife, phillips head screwdriver/bit, cordless screwdriver/drill, jigsaw with blade (I used a Bosch basic metal blade (U118A)), and a small drill bit about half the diameter of the P3 mounting screws. 1) Remove the four trim pieces in the Suburban (search WWW for videos). 2) Remove the existing subwoofer. 3) Using the Skil jigsaw trim the exterior plastic / metal ring on the Rockford Fosgate leaving only the screw holes. 4) Jump the two terminal sets on the speaker like you would a car: negative to negative and positive to positive. This makes the speaker 2 ohms for the factory amp. 5) Hold speaker to enclosure and drill four new holes. 6) Strip and attach the factory speaker wire to one set of the speaker terminals, screw into place with the included P3 mounting screws, test, and then replace the four trim pieces.

Pros: Good sound and punch, reasonable price, fits my car, relatively easy to install

Cons: Requires modification to fit my vehicle which, in turn, voids the speaker warranty.

Great bang for the buck

Terrance from Houston, TX on 4/13/2018

2005 Lincoln Aviator

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

Replaced my factory 8" and I was immediately impressed by the sound it created, not the best at catching lows but for the size it does a decent job, I also am still working off the factory amp which is for the sub exclusively I'm my 2005 Lincoln Aviator, I'm sure if I updated the amp it would be that much better. The mids are extremely crisp and the break in time was relatively short. My next step is to upgrade the door speakers which i will also be ordering from Crutchfield in the near future.

Pros: Great factory replacement in 2005 Aviator, easy installation, crisp mids, decent lows

Cons: I may need to upgrade amp, but not bad for a factory replacement with factory amp

Serious for an 8 Inch sub!

Robert from Lancaster, OH on 5/22/2017

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

Due to some modifications that I didn't expect, I haven't had a chance to install this sub yet. However, right out of the box this speaker seems like it's one serious machine! Heavy and seemingly well made. I plan to update this review after install so can offer 5 stars.

Pros:

Cons: none yet, haven't installed

For the price, it exceeds what I expected. Provides just the right amount of thump

Pros: Fit right into the truck's stock enclosure without having to make any mods

Cons: Couldn't use the grill it came with but it's not like you can see it anyway

Features

Shallow Mount Design: The Rockford Fosgate Punch P3S shallow subwoofer is designed and engineered with a more shallow motor assembly, reducing the overall depth of the woofer and allowing it to fit in smaller locations in your vehicle.

Dual Voice Coils: This woofer features dual 4-ohm voice coils for wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 2-ohm load. When the voice coils are wired in series, the woofer presents an 8-ohm load.

Compression Terminals: The P3SD4-8 features spring post terminals which accommodate pin connectors, single banana plugs, or bare speaker wire up to 10 gauge.

Note: The rubber magnet cover may need removed (or repositioned) to insert pin connectors or banana plugs.

CEA-2031 Compliant: Power handling conforms to CEA-2031 industry standards, meaning the subwoofer has the capacity to handle its rated power under continuous demand, not just for an instant.

VAST Surround: The Vertical Attach Surround Technique (VAST) increases a speaker's effective radiating cone area without increasing the size of the basket.

FlexFit Basket: The Flex Fit frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted.

Trim Ring: For added cosmetic appeal the woofer comes with an aluminum trim ring that mounts over the flange of the woofer. When using the trim ring, the woofer is first mounted with four screws, then the ring is mounted over the woofer, aligning the final four holes of the woofer with the ring. The other four screws are used in these holes to mount the ring and woofer to the enclosure. The trim ring increases the mounting height of the woofer to approximately 1 inch, and the ring's diameter is approximately 9 inches.

Enclosure Compatibility

Sealed Box: Rockford recommends a sealed enclosure with an optimum internal volume of 0.25 cubic feet (from 0.2 to 0.70 cubic feet is acceptable). Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.

Ported Box: Rockford recommends a ported enclosure with an internal volume of 0.75 cubic feet using one 3" diameter x 9" long port; this yields a tuning frequency of 47.5 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power. However, this efficiency comes at the expense of very low frequency output (below 37 Hz).

A
The factory 8" subwoofer in my 2016 Honda Civic popped. I bought this car specifically because of the "premium" sound system. It is not premium so I will have to do some modifications, but this sub should allow me to utilize the factory allotted space to have a much better sounding system. This speaker will also run with the factory amp, so I won' have to install additional amps. [ Jason  Nov 10, 2017 ]

[ Paul  Jul 21, 2019 ]
1 answer
A
Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

Will this fit in the factory rear deck location of a 2008 Honda Civic Si Coupe and being powered by the factory Navigation Unit and Amplifier?
[ Wiyet  Jan 24, 2017 ]
1 answer
A
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.

Q
There is 1.5" of space between the floor of my vehicle and the bottom of the box. Will this subwoofer work or will the cone hit the floor?
[ Travis  Feb 04, 2014 ]
2 answers
A
I would need more info. What box? What vehicle? Are you looking to mount this as a free air woofer firing down at the floor? If so, you would need to the woofer excursion spec. (the distance the woofer travels)
[ MITCHELL  Feb 13, 2014 ]
A
I'm really not understanding why the distance from the box to the bottom of your vehicle matters about this woofer working. My question to you is, are you concerned about the Woofer fitting in the Box or the Box fitting in you Vehicle?
