Built tough

Regular cab truck owners — Rockford Fosgate feels your pain. They've designed their Punch Stage 3 shallow enclosures so you don't have to suffer without good bass. And they build these boxes for strength and durability, with a computer-optimized design that uses medium-density fiberboard and thick carpeting.

Slim box, big bass

The P3S-1X12 sealed enclosure measures only 6-3/8" deep at its bottom, so it'll fit in the space behind many regular truck cab seats. It comes preloaded with a single 12" Punch Stage 3 shallow dual voice coil subwoofer that'll handle up to 400 watts RMS. The enclosure's low 1-ohm total impedance means it'll drive your amp to its max — just make sure you pair it with a 1-ohm stable amplifier. If you're looking to save space, Rockford Fosgate's super-small Punch PBR300X1 amp is a good match for this enclosure, generating 300 watts RMS at 1 ohm.

Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

Needed a sub to compliment the focal components I installed in my 87 F150 standard cab truck. I went with this sub, and the alpine M110 mono amp and I am amazed at the power this single little speaker has! The amp I bought is over kill I suppose, but if your careful and stay away from temptation of to much gain, this bad boy will rock your truck with clean solid hits. It was smaller in over all size in the sealed box than I was expecting, so two will drop in behind a standard full size truck cab without a problem.

Pros: Quality unit that hits hard and keeps it small on space. Good price to

Cons: None

Amazing sub

This sub for the price it comes with is worth every penny. I have it installed in my 1994 Chevy 1500k. no crew cab so it fits right behind the seat perfectly. The sound quality is amazing for such a shallow sub. I have it paired with the Kicker 10DX500.1 and it is simply amazing. Its rugged and thats even with how it got to me the shipping box it was in was all cut and crumpled, I thought the sub was gonna be punctured and what not, but to my astonishment is was perfectly fine. If you are looking for a small sub this one delivers every time!

Pros: Sound Quality, Build, and it just looks cool

Cons: NONE

Punch Woofer: The enclosure houses one front-firing Rockford Fosgate Punch P3SD2-12 shallow mount 12" subwoofer. The dual 2-ohm voice coils are internally wired in parallel to present a 1-ohm load. The sub features a StampCast basket, an Anodized aluminum cone, and Santoprene surround. The integrated spider venting helps keep the subwoofer cool.

Enclosure: The truck-style sealed enclosure is constructed with 1/2" MDF and covered with high density black carpet. The enclosure features high current spring posts of the right side. The box is shallow enough to fit behind the front seat of many standard cab pickups.

Box Carpeting: The enclosure is finished with high-density black carpeting for superior durability.

Speaker Terminal: The subwoofer enclosure uses one pair of high current, spring loaded binding posts. The binding posts are located on the right side of the box and will accept pin connectors, single or dual banana plugs, or bare wire up to 10 gauge.

Power Handling: The subwoofer can handle up to 400 watts RMS, 800 watts peak.

CEA-2031 Compliant: Power handling on the P3S-1x12 conforms to CEA-2031 industry standards. This means the subwoofer has the capacity to handle its rated power under continuous demand, not just for an instant.

This box just fits behind the back seats in my 2006 GMC Sierra quad cab pickup truck. Use the measurements they give and compare to the size of the compartment in your jeep. [ Gregory  Dec 28, 2015 ]
The available area we have on file for mounting a sub box in the rear/hatch of a 2015 Jeep Wrangler is: Width (side to side) = 35" (with factory sub) or 41" (without factory sub), Height = 12", Depth (front to rear) = 9" at top, 12" at bottom. This Rockford box appears a bit too tall to fit into that location. [ Larry  Dec 26, 2015 ]  Staff
