Rockford Fosgate P2 Series Subwoofer

P2D4-15 Punch P2 Series Subwoofer

When it comes to car subwoofers, Rockford Fosgate raised the bar in terms of high quality affordable subwoofers. These Punch Stage 2 subwoofers are the perfect combination of price and deep bass. The new Punch Stage 2 series will crank out 300 watts of RMS power handling, giving you that nice deep bass without over powering your audio system. The face of the woofer has been upgraded with a kevlar reinforced paper cone that will provide durability and great sound quality. For those long sessions of hard hitting bass, the rubber surround has been manufactured to handle high excursion movements through out the day. With their patented technology the Rockford Fosgate P2D4-15 are the perfect match for those looking for quality bass without breaking the bank.

While built on a long standing history of performance, the punch series woofers can deliver not only output to satisfy you when you want it loud but maintain a level of sound quality for when you really want to "listen" to your music. Taking many design cues from the Power Series, Rockford Fosgate engineers continue to improve the Punch Series year after year making it one of the most sought after woofer lines for music and bass enthusiasts alike. With features like Dual tear & fatigue resistant poly-cotton spider for high strength and anodized aluminum voice coil formers to handle heat buildup in the motor structure under full power situations, these drivers are designed to perform.

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 buy!

The following review is for P2D4-15, which is a part of the bundle you are viewing.

I own the 12" version, and these things pound. They advertise 400RMS off these, but you can push them harder. I'm topping out my 1kw RMS on two of these, and they handle it with ease.

I have this sub in a ported box in my suv and it's super loud. I have a 500 watt mtx amp pushing it, omg it bumps, teacher at school hates it. I out bump everbody it's so loud the I can no longer park at school. I would recommend this sub to anybody who wants a bump and not go broke.

It's massive. used this P2 for my hyundia and I love it. Comes with a decent manual so you can hook it up in a variety of ways plus it tells you what size box you should use. Only wish i got the higher RMS one. but hey this things is awesome

The following review is for P2D4-15, which is a part of the bundle you are viewing.

I bought this subwoofer a few months ago and I have no complaints about it. I have it being powered by a P500-2 amp but soon, I'm gonna upgrade to the RF T-1000bd and run the power to a 2 ohm load and power the P2 for 650 watts. I would try for more power, but since I use this in my truck as an everyday driver, it's really not needed.

If your looking for something that's affordable, looks good, and want something that will get you head nods from even the most extreme car audio fanatics, this is the sub for you!

Great product!

The following review is for 15SQV, which is a part of the bundle you are viewing.

I would recommend this product because it complements my sub perfectly and it's build very sturdy. Make sure you check your trunk dimensions before the purchase of this product for it's a bit bulky and might take up quite a bit of trunk space but if you have your mind set on purchasing a 15" sub this must be something you are already willing to give up for great sound. I would also suggest you fill the inclosure with polyfill to add a deeper bass. Overall if you are buying any kind of enclosure for your sub I would highly recommend purchasing a ported one like this one A+ product
