Taking Punch to a Higher Stage

The P3SD2-12 Punch Series 12" Shallow-Mount Subwoofer has a peak power rating of 800 watts and a RMS rating of 400 watts. It is capable of producing some earth shaking bass and is constructed with an anodized aluminum cone and a vertical attach surround technique. This woofer is also equipped with a 2-1/2" Voice coil and a protective PVC textured magnet cover. Rockford Fosgate understands all vehicles are not the same, because some cannot accommodate deep subwoofers. In the past, that meant no Bass. Not anymore! Now even depth challenged vehicles can have REAL Bass and the Dual Voice Coil allow configurations for every application.

Anodized Aluminum Voice Coil Former

Anodized Aluminum Voice Coil Former

By using an anodized aluminum voice coil former on their subwoofers, Rockford Fosgate is able to dissipate heat from the voice coil more efficiently. A hot voice coil can melt the adhesive bonds, which will lead to eventual subwoofer failure. The aluminum voice coil former acts as a heat-sink to dissipate thermal build-up on the voice coil cool during high SPL conditions.

CEA-2031 Rockford Fosgate Subwoofers

Conforms to CEA-2031

Rockford Fosgate has built this subwoofer to conform to the CEA-2031 loudspeaker power handling industry standards. This means that you can trust the subwoofer to have the capacity to safely handle the continuous (RMS) power rating. Having a CEA-2031 power handling is important when matching a subwoofer to an amplifier because the power ratings are accurate.

Rockford Fosgate Stitched Tinsel Leads

Stitched Tinsel Leads

To improve the reliability and performance by reducing fatigue and possible shorting, Rockford Fosgate has stitched the tinsel leads to the spider. The multipoint periodic stitching lead wires reduce the mass of the tinsel leads to spread the stress over a greater area. This improves the reliability and performance of the subwoofer.

Rockford Fosgate VAST Surround

VAST: Vertical Attach Surround Technique

In order to increase the surface area of the cone without causing any installation issues, Rockford Fosgate designed the Vertical Attach Surround Technique (VAST). By redesigning the manner in which the surround adheres to the basket, these speakers gain up to 25% more effective radiating cone area. This improves the nominal efficiency and maximum output.

Great Shallow Mount Sub!

The following review is for P3SD2-12, which is a part of the bundle you are viewing.

I put this sub in a ported box in my 2007 classic silverado with a kenwood 9106d amp (500 watts RMS @ 4 ohms) and it sounds great!! It sounds accurate and can really bump for a shallow sub. If something happens I will change my review accordingly but as of right now this was a great purchase! BTW when i bought this sub the sonic electronix website said the frequency range was only to 43 hz, in the owners manual it says 34 hz.

The following review is for P3SD2-12, which is a part of the bundle you are viewing.

I bought one of these for my 07 f150 to go underneath my back seat. This sub was great for the small space I had. The bass is so clean and tight and hits nice and hard. Would recommend this to any one. Well worth the money!

Small footprint, sounds great.

The following review is for P3SD2-12, which is a part of the bundle you are viewing.

I bought this sub as an alternate for my big box so I can use the third row in my vehicle. I installed the sub in an Atrend thin profile ported box and I'm pushing 750W RMS at 1ohm.

The sound quality is pretty good considering it's a thin mount sub. It'll miss out on the low end but it's very serviceable. To improve the loudness, I added some polyfil to the box. It certainly helps.

It's a great sub for the price. I don't expect anything less from Rockford Fosgate. Well done.
