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 ....

The following review is for R2D4-12, which is a part of the bundle you are viewing.

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.

Doing the job

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

It's true when people say the box makes the subs.i have two p3 d4 dvc 12's and the crappy prefab that I had them in was being pushed apart, in a literal sense. I bought this box and now it's clean bass and the box is holding.

Nice budget subwoofer

The following review is for R2D4-12, which is a part of the bundle you are viewing.

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

The following review is for R2D4-12, which is a part of the bundle you are viewing.

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
