Rockford Fosgate

Authorized dealer

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. With a RMS power rating of only 250 watts, these subwoofers are designed for lower wattage amplifiers. However, don’t be fooled by the lower power rating. These efficient woofers are fully capable of producing crisp, clean bass that will shake you to the core. As with all of the other Rockford subwoofers, they have packed patented technology into this sub to enhance the performance of the subwoofer. The Venturi-effect cooling system helps to keep the voice coil cool, while the double stacked ferrite magnet help maintain the power. On the face of the woofer is a polypropylene cone and ABS/Acrylic dustcap. A little further out is the half-roll sealed poly-foam surround that assists with the high excursion of the motor assembly. For those that need a low wattage and high output subwoofer, the Rockford Fosgate Punch P2D412 is the choice subwoofer.

Updated Review

i just wanted to update for all wondering if they should buy this sub or not. YOU SHOULD. ok so i still have these runnign off my kicker, with a rockford 500-2 for the highs. got the bass knob, so the boost on the amp is full, and gain is a lil below 3/4 on the amp for safety. these babys slam dude. like, choking almost. and ther 2 12's. i have them facing inside my car in my 99 grand am gt with the back seats folded down in the rockford fosgate box with the ports (i took those out and made mdf seals for the box, sealed them in and painted because i like sealed better) and its insane how loud these are. the one has been through absolute hell, no other way to put it. i turned them around because i use my trunk alot and stuff gets tossed at them all the time unfortunately. so the one sub is destroyed, appearance wise. i had them reverse mounted in a sealed box at one point and due to the fact that the dust caps were cracked in the first place, it exploded. the dust cap literally exploded. so that one is trashed and has some tears in the surround, while the other one spent most of its life in my room its in fairly good condition, not being as broken in as the other one. and they still pound like ther aint no tomorrow. these things are invincible. they sustain so much unintentional abuse and still never back down. i love these things and want to get 2 more so i can hav 4 12's. MUST BUY if your just lookin to get a good bang for your buck. Rockford's are quality built. cant go wrong.

great sub

I have had two sets of these subs, one set was stolen, then i went to kicker, then back to rockford for the best sound, they hit harder and cleaner than any subwoofers that i have heard in my vehicle,
Pros: clean bass, nice look, hits lows well
Cons: the durability could be better, the front of the subs can crack easy, but they sound does not change
Overall a great subwoofer, have my two being pushed by Rockford Fosgate T-500, gives it great kick

I have owned these suckers for couple years now (one older version and other is this version) and they are the best ever! After breaking them in, one decided to quick working (wire broke inside or something, seemed fine but wouldn't work) so I sent it in to have it fixed, they sent back a brand new one for free (just had 2 pay shipping)!!! Both work awesome now and have out lived the amp (got too warm and quit workin the other day). Best bang for the buck...Literally! Kicks the s*#t out of my coworker's $300/each subs! Buy these bangers now!

Fosgate update P2D412

Rockford lives up to its rep

WOW, for a 500w max sub, it hits lows harder than a 1000w or 1500w sub can. That precision engineering. I presently own 1 hooked onto one channel on my punch 400.2 amp and it throws about an inch and makes my car shake. i have 2 brand new ones coming in from sonic, who's prices were cheaper than ebay sellers for the p2's.
Pros- Hard hitting powerful lows
Cons- slightly weak mids, but sound quality is there

Decent sub.

I have one of these in my chevy hits hard, but my MA-Audio was way louder, but this sub has cleaner my volfenhag sub...ya that was wayyyy better than this sub, although the durability wasnt to great on it. so if you want clean bass and a durable sub, this is the way to go, now if you want LOUD...get the p3 or higher, or just go with kicker or ma or but still a nice sub none-the-less.

quality sub

I installed a 12" p2 in my truck and for the price, I don't think I could have bought anything better. I really abuse this sub pretty hard, and unlike my old blown sub that was even rated for higher power, this sub has held together no problem and continues to thump out those low notes like new. 100% satisfied

Excellent Sub for the price

I purchased an older version model P212D4 and that was in Oct. of 2006 and to this day my 12's still bump excellent punch bass. Some times I check the non ported box and the bass knocked out a external speaker port. I am serious people if you are looking for great bass at a superior price buy these subs. Oh and it would help if you match them with a 500 watt punch amp old school version if you can find one cause trust me old school power is just better with Fosgate.
