Advanced engineering

The P3SD4-12 12" shallow-mount sub hangs with its bigger brethren, thanks to advanced materials and engineering. Rockford uses an anodized aluminum cone and dust cap that makes the woofer light and easier to drive, yet rigid enough to maintain its shape when you turn it up loud. 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 sub, with abundant venting to battle overheating and thermal breakdown. At 3-11/16 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.

Features

Shallow Mount Design: The Rockford Fosgate Punch P3SD series shallow subwoofers are designed and engineered with a more shallow motor assembly which reduces the overall depth of the woofer, allowing it to fit in smaller locations in your vehicle. The P3SD4-12 uses an anodized aluminum cone and Santoprene surround. An anodized aluminum voice coil former and spider venting help keep the subwoofer cool.

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.

CEA-2031 Compliant: Power handling on the P3SD4-12 subwoofer conforms to CEA-2031 industry standards. This means the subwoofer has the capacity to handle power under continuous demand, not instantaneous power handling, that over time, can damage voice coils.

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

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

Anodized Aluminum Voice Coil Former: Aluminum voice coil formers offer superior heat dissipation over other commonly used materials. The hard-anodized finish increases the former strength. These two factors combine to improve the overall power handling characteristics of the subwoofer.

Spring Post Assemblies: The woofer features custom insulated/isolated compression input terminals with attached flexible, 16-gauge stitched tinsel lead wires that can withstand extreme duty cycles, fatigue and high current. The heavy-duty spring posts will accept pin connectors, single banana plugs, and bare wire up to 10-gauge.

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 ring. The other four screws are used in these holes to mount the ring and woofer to the enclosure. The trim ring increases the top-mounting height of the woofer to approximately one inch and the ring diameter is 13-3/8 inches.

Break-In Period: Due to the design of the Rockford Fosgate P3 Shallow subwoofer, a 24 to 48 hour break-in period is required to allow for maximum excursion and low frequency extension. The shallow woofer suspension is intentionally designed to optimize once the internal components are exercised under normal music listening conditions.

Enclosure Compatibility

Sealed Box Volume: The sealed box size range recommended by Rockford Fosgate is 0.60 to 1.20 cubic feet. Within this range, the ideal recommended size is 1.0 cubic feet, resulting in a 3dB down point of 40 Hz and a Qtc of 1.01.

Vented Box Volume: The vented box size recommended by Rockford Fosgate is 1.25 cubic feet. One 4" diameter x 12" long port should be used, resulting in a tuning frequency of 42.5 Hz and a 3dB down point of 34 Hz.

Q
Would a Kicker 46CXA660.5T be a good amp to drive one of these subs?
jimwhiz  Feb 24, 2023
1 answer
A
I think that would be a great pick, James. The Kicker amps are reliable and a great value, some of our most popular amplifiers! This Rockford Fosgate P3SD4-12 can handle 400-watts RMS max, a good match for the 300-watts the Kicker's subwoofer channel pumps out. This is also the dual 4-ohm model, so you will show 2-ohms at the Kicker amp and get the most power. I see no issues here, especially if you want great sound!

I only used 1 sub and wired it to 2 ohm to match the amp that we used.
william  Nov 19, 2020

If you go on fosgate website they have a wiring wizard program that will walk you through how to wire the sub or subs for what ohm load you are looking for to maximize the wattage from your amp

Q
Can i run the sub on free air or infinite baffle?
johnny  Jul 04, 2019

A
This sub is NOT designed for free air use, you would need an enclosure with it.
thomas  Jul 12, 2019 (Staff)
Q
I have a box that's .60 cu ft was wondering if I put polyfill in if it would help or just not worry about it since it's in the range of what the sub calls for?
joey  Jan 15, 2018

A
Sealed enclosure correct? If so, no, there's no need to use Polyfil with that amount of airspace.
ryan  Jan 20, 2018 (Staff)
Q
What amp would you recommend to run 2 of these subs?
kristopher k  Jul 25, 2016

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.
kenneth  Jul 25, 2016 (Staff)
Q
The only box I can find for my avalanche is .48 cu ft. Will they still work and sound good in this box?
adam  Jan 24, 2016
1 answer
A
The sealed box size range recommended by Rockford Fosgate for the P3SD4-12 is 0.60 to 1.20 cubic feet and the ported box size recommended is 1.25 cubic feet. If you have a sealed box that can fit the top mount depth of this sub (3-11/16"), then it should work, however it would perform best in a box with a larger internal volume.
