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.

good box

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

Makes my 2 pioneer champion series 600 rms 12's sound like thunder! Hits harder than my 4 kicker comp vr's in a sealed box that is powered by the same kicker 1600.1 amp!

Does what it is supposed to

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

If you need a box built quick and dirty to hold subs, then this is for you. Not the best built, not the best carpeted, not the best mdf, but hey, its a sub $100 woofer box. Works as intended for me, corner came dented in during shipping, carpet very thin, but it does hold subs, which is what i needed.

Great

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

I got this for two 12 inch Kenwoods and they sound amazing in this box, I originally had them in a under seat truck box that was sealed and now they sound much louder and just as crisp.

This box deliveres no doubt about it! Well built, carpet is of good quality, looks good! There isn't a better box for the money, will be ordering another, and definitely recommend this box, to anyone looking for some serious deep bass!
