Eliminate Entry Level and Go Straight to Prime

Prime subwoofers are ready to rock and are the perfect first step into performance audio.The Prime R2 12" subwoofers have a peak power rating of 500 watts and a continuous RMS power rating of 250 watts. This makes them an ideal subwoofer for anyone looking to add some modest low end to their car audio system. The Prime R2 drivers feature an anodized aluminum voice coil formers for extreme heat dissipation that allow the driver to perform at optimum level during long hard hitting sessions. These subwoofers are the way to go when looking for a woofer that is built with quality & performance in mind and has been designed by industry's leading car audio manufacture.

These woofers, like their Punch brethren, are built using many of the same speaker technologies that Rockford has been famous for over 30 years for and you won't break the bank buying one. Simply put, the Prime seriesof woofers are held to the same standards of quality and performance as any other Rockford woofer but delivered at an affordable price.

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.

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.

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.

Great value!

Got it about 6 months ago. Put in my Ford Ranger and bass sound from this is just what I was looking for. I now can thump like the kids down the street. I would recommend this. Thumbs up!

garbage ....

I bought a pair to go behind a 1200watt amp. They blew up in a day. I wasn't even listening to loud or music with lots of bass. They just burnt up. Thought my installer wired em wrong so I ordered another pair and had another professional wire them in... Blew them again in 2 days. Gain was low on the amp ... These are cheap for a reason.

Nice budget subwoofer

I have one these in a 2 cubic foot sealed box in my 94 civic coupe and it sounds awesome with any music. Its paired with a Rockford Fosgate Prime 250-1 and a Stinger amp kit. I've put the sub and amp through hours of abuse and never had a problem. I had two Kicker Comp 12's in there with an Alpine 500 in a ported box at 35 hz and they didn't sound near as good as this one subwoofer. This subwoofer isn't going to rattle the car next to you but you will be heard. I have people asking me what I have back there and I say its a 12 with 250 watt amp and they think I have a 15 back there. I'm like yeah you can have awesome bass without upgrading your alternator and battery. Just do your research and you might be surprised with lower end name brand audio equipment. Hope this review helps.

Deyz little thangs bang

Aww man these bad boys hold there own had two in my girls firebird on a 1000 watt amp and let me tell you they got down right busy they embarrassed my homeboys 3 10" kickers made my love for Rockford that much stronger make sure you properly break them in though cuz they will stink up the ride when abused lol but I fully recommend for the casual bass addition not so much for the junkies like myself

Rockford Fosgate R2D4-12 (R2D412)

This sub is amazing. At first i was shotty of the prime series, but have i ever been proven wrong. i have 2 of these hooked up to a punch 500-2, and they slam hard. i do suggest a ported box. for the price, they are amazing

powerful subs, MUST buy

These subs hit HARD, i have 2 in the trunk of my Ford Focus sedan with a crossfire C3501 amp, and ive been running this system for about 6 months. It has won me some money, and even been in the top 10 of audio comps, these subs handle power well, and ive been pushing them hard for 6 months, and they run like a charm, the range is really good, but they hit the hardest between 30 and 75hz, If your looking for a good alternative to kicker CVR's or Apline type R's, these are your go to, and for a great price. I plan on upgrading to a 3 12's with these exact subs. I must say I love Rockford Fosgate and am a life-long buyer.

Great Bass

I wanted some bass but this provides A LOT of bass. It sounds great but still allows you to hear the high frequency sounds. The bass is not distorted either.
