2 Punches and You're Out!!

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 2011 Punch Stage 2 series will crank out 400 watts of RMS power handling, giving you that nice deep base with out 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 P2D4-12 are the perfect match for those looking for quality bass without braking the bank.

 
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.

I took a gamble on the RE Audio SRX 12 with dual 4 voice coils after reading tons of great reviews on them. I was unimpressed as it just didn't sound as musical as previous Fosgate subs, even cheaper ones. Also, the stitched tinsel leads broke loose and it wasn't even a month old. Sonic let me return it and upgrade to the Punch P2D4. Very glad I did, this sub hits way harder and sound far more musical than the RE. Its well worth the extra cash. I've been driving it hard with 300 watts no problems at all, even with the bass boost set at 40hz and cranked high.

If you've owned Fosgate products before and are considering saving a few bucks to go with a budget brand, save yourself the trouble and get the real deal.

No complaints with the sub. Sounds great and can hit hard if desired. In a ported box with a 400W amp. Works great for me.

I have a pair of the p2d4-12s where my backseat used to sit. Not that I need that much space because they only require 1cu ft of air. But I have them in custom ported enclosures which are consideribly larger. But with just these powered by a Punch T600 you can literally see the air pushing the quarter panels on my car. Stick your head next to the window and you can feel your hair moving. My car is all black so the smooth clean black look with the machined trim ring was a perfect compliment to the "blacked out" look I was trying to keep. They are so much better than the old school 15s I had back in the day which took up so much mor space! I recommend these to anyone looking to upgrade to a great sounding system but doesn't want to lose every inch of you trunk space...

I currently have three of these subs in my car. I run 2 of them off of kicker 1000.1 dx amp and 1 off of the kenwood 9105d amp. Kicker amp puts out 1000 watts rms and the kenwood at 2 ohms is 900. I love these subs I still have one of the older generation p2's with the plastic cone which is broken and it still bumps. The two newer generation subs definitely look better and im sure the cone holds up better then the older one. Im currently saving up to buy 2 p3's to replace the busted p2. Make sure you buy a good amp to power these subs. The kenwood amp is the 3rd amp i had with the p2's and the kicker amp is the 4th. These subs sucked the life outta the cheaper amps. I recommend the grill with these subs because they bump so hard if anything touches the cone it's either gonna tear up the cone of what ever is touching it from experience. Oh and last with a good amp its gonna suck alot of power so make sure to get a cap. I have 50 farad cap and with the 3 amps my lights still dim a little bit.

This sub hits really good and looks great. I have been running it hard non-stop from day one. It sounds powerful, tight and clean. I have also pushed 500W RMS for awhile with no problems, this sub is tough. My only concern is why the basket is designed with plastic (or thin metal). A little cheap, but I don't see any issues arising from it.
