Advanced engineering

The P3SD2-8 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 2-ohm voice coils allow you to wire up multiple subs or to coax optimum performance from your amplifier.

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 2-ohm voice coils for wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 1-ohm load. When the voice coils are wired in series, the woofer presents a 4-ohm load.

Compression Terminals: The P3SD2-8 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).

Will this sub fit the RetroSound R-TWENCL enclosure?
[ John  Jun 10, 2019 ]

A
It would not be a great match as the cutout on that retrosound box is bit too large from that rockford sub. the box we have listed as fitting that Rockford sub is this : https://www.crutchfield.com/p_777BB835S/Sound-Ordnance-Bass-Bunker.html

Q
can a single 2ohm dvc sub be wired for a 2ohm amp?
[ Juan  May 25, 2019 ]
1 answer
A
No. If you only wire one voice coil, you will burn up the speaker posthaste. If your amp outputs at 2ohm, you will either need a single 2ohm voice coil, or a dvc with 1 ohm per coil(unlikely) wired in series, or a dvc with 4ohm per coil wired in parallel.

Q
Fosgate P3 slim 8" . Would this speaker fit in my 2008 toyota 4 runner?
[ rick  Mar 22, 2019 ]
3 answers
A
I installed in my 2003 4runner with no modifications. Sounds great.
[ Zen  Mar 22, 2019 ]
A
Yes. I put this speaker in my 2004 4Runner last year and the '04 and '08 are the same generation/body style. It took me about an hour to get it in using the step-by-step instructions that Crutchfield provided. I think I had to shave a little plastic off of the interior panel that covers it because this speaker is a little thicker than the stock speaker, but it wasn't much work and didn't damage anything in the vehicle. The speaker sounds good...much better than the stock speaker.
[ Robert M.  Mar 22, 2019 ]
A
It fit perfectly in my 2007 Toyota 4runner so I'm sure it would in your 2008.

Q
Is this a direct replacement fit for a 2016+ Civic with factory sub?
[ John  Feb 08, 2019 ]
1 answer
A
It is not a direct replacement subwoofer for those cars. Right now, I don't have one that is a direct replacement, but we may have some that can be adapted to fit. I recommend contacting an advisor on 1-800-324-9695 to check our current options My Bio: https://www.crutchfield.com/bio/Paul

Q
Does this work in a free air application?
[ Jason  Aug 05, 2018 ]
1 answer
A
Yes it will produce sound, no it will not sound good. Without resistance air pressure on the speaker, it's resistance rating will be skewed, meaning it will be wildly inaccurate with unfocused tone. In other words, quiet and flappy.
[ Justin  Aug 08, 2018 ]
Q
With this sub (Rockford fosgate p3Sd2-8) are you able to mount it with the back touching the enclosure?
[ Philip  Feb 23, 2018 ]
1 answer
A
I didn't have this problem. From my experience with speakers, it's best to not have any part of the speaker other than the mounting ring touch any surface in order to eliminate any vibration. If you think this speaker might have this problem, look for a flatter speaker, or see if you can add a spacer plate between the mounting surfaces.
[ Rodger  Feb 23, 2018 ]
Q
Is this sub able to be mounted with the back pressed against the enclosure? (Rockford fosgate P3SD2-8
[ Philip  Feb 23, 2018 ]
2 answers
A
I believe the subwoofer can be mounted with the back pressed against an enclosure provided that you put a dampening device such as a rug or EVA foam between the sub and enclosure wall. to isolate any rattling from the enclosure. I have my sub mounted in the a somewhat tiny crevice with insulation. My RF P3SD-8 Sub Works Great!
[ Ermie  Feb 23, 2018 ]
A
Hi I installed this in its factory location and this speaker was too powerful for that location , it rattled the back of the factory location so i would say no to your question, I actually put it into a sub box and put it under the back seat and it sounds great
[ stephen  Feb 23, 2018 ]
Q
What amp would be good for this speaker?
