Nice deep bass, installed in a single box behind the seat and i poly filled the box. Bass was nice and clean.

Bought this because it was one of the few subs that would fit under the rear seat of my 2012 Ford F150. Having used it for 6 months now I can say I would gladly buy it again. It doesn't shake the paint off the doors but that was not what I was looking for. I replaced all the speakers and used an Alpine amp for the mains and a Kicker for the sub. It took the sound from horrendous to really very good for very little cost.

I bought two of these for my 2006 Extended Cab Silverado and hooked them up to a 1200 watt 400 RMS amp. I have to say that these things are amazing for the price you pay! I was limited on space so I had to go with shallow mounts and I am very impressed with the performance of them. I would recommend these to anyone who has a limited budget and still wants nice, clean bass. Make sure you get the right amp for them though!

Execellent sub I am currently running two of these subs with the 1000 watt Kenwood 2 channel amp and they pound. I am very pleased with these purchase. Like I said before I love kenwood, they make kenwood and rockford fosgate what a great combination. If you want good deep base buy these combo, the price is right and your friends will envy you.

I have it on the back seat of my f-250 diesel crew cab. It sounds and feels real good.. I'm very happy with these purchase. Big difference, and just right!!
