Our take on the Rockford Fosgate P3-1X12

Standout performance

Rockford Fosgate's P3-1X12 ported enclosure offers the extra power handling and advanced heat dissipation of a Punch P3 12" sub, so you'll hear impressive, crowd-drawing bass that just won't quit.

Heat-sink aluminum cone

The enclosure houses a Punch P3 12" sub, with a rigid anodized aluminum cone that holds its shape through heavy play, while staying light and responsive. The aluminum cone acts as a giant heat sink, and works alongside advanced cooling vents to direct heat away from the copper-clad aluminum voice coils. These innovative cooling techniques, plus a heavy-duty motor assembly, let this sub handle up to 600 watts RMS without flinching. The sub's dual voice coils are wired for a 1-ohm total impedance, so make sure your amp can power this enclosure safely.

Advanced port design

Rugged 5/8" medium-density fiberboard construction means this enclosure will hold strong for fat, heavy bass. Industrial-grade black carpet provides a clean, finished look, and protects your trunk from nicks and scratches. The spring terminals will accept bare wire, pin connectors, or banana plugs. This enclosure uses an advanced port design that promotes generous air movement, while reducing distortion-causing port noise, so you hear louder, deeper bass. Add an amp and some wiring, and feel the thick low end this enclosure adds to your ride.

  • ported hatchback-style enclosure with one 12" Punch P3 subwoofer

I have had many high end systems over the year the past 20 years, costing several thousand dollars. I went with something simple, yet powerful when choosing this sub. I have a Mazdaspeed3 that is highly modded, and I wanted something that wouldn't take up a lot of space without sacrificing powerful bass response and accuracy. I used to be a bass head, but as I got older I now listen to a variety of music. It takes a lot to impress me. However, I'm so impressed with this sub! I have the factory Bose system, so I kept my stock door speakers for now. I used a Rockford 4ga amp and a Precision Power Sedona 850x1 mono block amp to bring this sub to life. I'm still breaking it in after a week, but I actually have to turn down the amp to keep from drowning out the highs with the tight and rich bass I now have. With songs that have a natural bass made from a kick drum, it is not muddy at all. I'm met with a gut churning "punch" from this awesome P3 sub. I was a little worried about the high tuning of the box, which is around 40hz. However, the sub continues to get low and play deep with authority all the way down to its min frequency response at 26hz. I have it crossed over around 100hz to keep out unwanted frequencies. For a very nice, budget friendly sub, you can't go wrong. I just came from a Sundown SA 10 in a vented enclosure, and this sub blows it away. I though Rockford had gotten watered down over the years. Boy, was I wrong!! Definitely invest in a strong amp though.

Pros: Tight and powerful bass

Cons: None so far

Crutchfield Customer Review (What's this?)

I love heavy bass and setting car alarms off and you definitely get your bang for you buck with this sub/box combo. Tuning the sub for electronic music will work well with this. I can pretty much listen to it at 8 and still hear the bass then when I barely crank it up it thumps. I currently have 300rms going to it now I can only imagine when I put it to its true potential with the 600rms amp.

Pros: Tons of bass. Price is worth it. For a older sub it still plays very hard. It's a top of the line subwoofer.

Cons: Pretty big box. Does not come with grill for the speaker


TURBOJOE from Long Island NY on 10/1/2014

I recently had one of these installed in my 2010 Mazdaspeed 3 and let me just say it sounded above my expectations, I was looking for a little bump and what I got was pounding clean bass. If you are looking for a sub take a listen to this. The rest of the speakers are all stock running off a Eonon (china) 8 inch double din that sounded great till I put this sub coupled with a RF T-3002 and 1F cap and now it just blows you away.

Pros: Sound,Price,Quality,Looks

Cons: NONE

Hard hitting sub

victor from Sacramento, CA on 2/17/2013

This sub hits hard!! Rockford Fosgate never fails to disappoint. Box seems to be put together very well and seems very sturdy. This is my first RF sub and I would recommend them and will be buying them in the future. This sub was an upgrade from a kicker solo baric 10in. I have this sub in the trunk of a honda civic. Have it running off a kicker 500 watt amp at 1ohm, this amp has a bass remote as well (very convinient if you listen to lots of different kinds of music). paired with 6 1/2 kicker front speakers and 6x9 kicker speakers in the rear deck, the speakers are not amplified just running off a kenwood head unit. If you want a sub that hits hard and delivers tons of low bass this is the sub for you.

Pros: -Hard hitting bass that doesn't quit -looks cool -great sub for the price

Cons: Girlfriend won't like how loud it is

Great Choice

Hands-on research

Product Research


Punch Woofer: The enclosure houses one front-firing Rockford Fosgate Punch P3D2-12 12" subwoofer. The dual 2-ohm voice coils are internally wired in parallel to present a 1-ohm load. The sub features a hybrid StampCast basket, an Anodized aluminum cone, and Santoprene surround. An anodized aluminum voice coil former and spider venting help keep the subwoofer cool.

Spider: Dual spiders made from tear and fatigue resistant poly-cotton improve mechanical stability under high excursion, maintaining consistent excursion characteristics.

Solid MDF Construction: The enclosure is constructed of high quality 5/8" MDF (medium-density fiberboard), which resists flexing and has anti-resonant qualities.

Vented Enclosure: The vented enclosure is aided by precision construction through computer design. The enclosure consists of one front firing 12" Punch P3 series subwoofer with a proprietary high-flow, low-noise port. The speaker terminals are located on the left side of the box (when facing the box). The box is covered in black carpet.

Tuned Port: The enclosure uses a front-firing proprietary high-flow, low-noise port to help produce deep and loud bass efficiently.

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

Speaker Terminal: The subwoofer enclosure uses one pair of high current, spring loaded binding posts. The binding posts are located on the left 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 600 watts RMS; 1200 watts peak power.

CEA-2031 Compliant: Power handling on the P3D2-12 subwoofer 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.

Dimensions: The depth dimensions listed in Features & Specs include the subwoofer's trim ring, which adds approximately 7/8 of an inch. The depth of just the enclosure is 15-3/4 inches at the base and 13-1/8 inches at the top.

I forwarded your question to an Advisor and they responded with the following: If you have all the wiring needs, you'll just need the line output converter to use it with your factory radio. I'd go with the AudioControl LC2i and you can check it out here: If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
