Engineers at Rockford Fosgate designed the P1S4-12 12" subwoofer to dish out the kind of powerful low end you crave in your ride. Its responsive paper cone is reinforced with the same Kevlar® fibers used in bulletproof vests so you get the best of both worlds — warm bass that's exceptionally hard-hitting. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases available cone area up to 25%, so this sub can push more air for even bigger bass.

The P1S4-12 sub features an extended pole piece and bumped backplate that leaves more room for heavy excursion, so it'll hit deeper lows without "bottoming out." This sub works equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.

Product Research

Enclosure Compatibility


Overview: The Rockford Fosgate Punch P1S4-12 is a 12-inch subwoofer with a single 4Ω voice coil. The sub features a StampCast steel frame, quick-release compression terminals, a Kevlar fiber reinforced paper cone, and NBR surround (Nitrile Butadiene Rubber). An anodized aluminum voice coil former and spider venting help keep the subwoofer cool.

Steel Basket: The P1S4-12 subwoofer features a StampCast steel basket for added rigidity.

Compression Terminals: The P1S4-12 features spring post terminals which accommodate speaker wire up to 10 gauge.

CEA-2031 Compliant: Power handling on the P1S4-12 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.

Trim Ring: To improve the cosmetic look, a decorative trim ring is included that mounts over the flange of the woofer. When using the PVC trim ring the woofer is first mounted with four screws, then the ring is placed on top of the woofer, aligning the final four holes of the woofer with ring. The other four screws are used for these holes to mount the ring and woofer to the enclosure. The trim ring increases the mounting height of the woofer to 13/16 of an inch.

Enclosure Compatibility

Sealed Box: Rockford recommends a sealed enclosure with an optimum internal volume of 1.02 cubic feet (from 0.7 to 1.8 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 1.79 cubic feet using one 3" diameter x 6" long port; this yields a tuning frequency of 36 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 32 Hz).

How. Many watts are the p1 speaker cuhz I have a 1600 watt 2 ch amp can it handle it and is it dvc?

The P1S4-12 is rated to handle 250w RMS and is SVC (single voice coil).
[ ZACHARY  Feb 26, 2023 ]  Staff
Can I wire the sub to a after market boss radio that has capability of 300watts?
[ ERICK  May 03, 2022 ]
1 answer
To get the most out of your sub, I'd recommend an amp to really drive the woofer and clean up the bass. If the Boss has a dedicated output for a sub straight from the head unit, you may get away with some decent sounding low notes out of your sub. If it doesnt, you're just wiring in another "speaker" to your head unit. Wiring the woofer to the head unit if it does has a dedicated output, will underpower the sub, in short, it will work, but not as well as it could.

[ Laundry  May 23, 2019 ]
There are markings on the speaker...either P1 or P2 should be visible.
[ GREGORY  May 22, 2019 ]
Can it be rewired to 4 ohm?
[ Kawaii  Mar 01, 2017 ]
3 answers
depends on how you wire it to the amp, the amp should b rated at 4 ohms per channel on 2 channel amps or 1 channel mono amps. if you have only 1 amp and 2 or more subs the ohms is split or doubled depending on how its connected. parallel connections split the ohms to the amp, series connections doubles the ohms to the amp.
[ charles  Mar 03, 2017 ]
It is a 4 ohm speaker. Hope that helps.
[ Fonda  Mar 02, 2017 ]
Yes they are 4 ohm speakers, what amp are you running
[ TIM  Mar 02, 2017 ]
what gauge speaker wire should i use for the Rockford Fosgate Punch P1S4-12 and a 400 watt amp?
[ SURGE  Jul 13, 2015 ]
2 answers
I used 10 gauge and it worked well.
[ MITCHELL  Jul 14, 2015 ]
14 Gauge or 16 Gauge wire will work fine both inside the sub box and from the sub box to the amplifier.
[ Benjamin  Jul 13, 2015 ]
What amp is most compatible with this sub? And if I had a performance teknique 800watt 2 channel amp connected, could that damage my sub?
[ jeremy  Dec 07, 2014 ]
1 answer
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.
