Great box for my type r

The following review is for BBX112BK, which is a part of the bundle you are viewing.

Box sounds great with a type r. I have mine wired to 2 ohms on a hifonics Brutus brx 2000.1 with a second battery and zero gauge wire and it sounds amazing

BANGER!!!

The following review is for BBX112BK, which is a part of the bundle you are viewing.

Bought this box for a 12" type r that i had in a sealed box. It hits sooo much harder in this box that i will never get a sealed box again. This box has a wider range than my sealed had with much more punch. I have 1 12 running on about 700w rms in a 08 camry and its a lot louder than people in know with 2 12's. The flush sub mount also looks great compared to the cheaper boxes on this site.

very nice sub box

The following review is for BBX112BK, which is a part of the bundle you are viewing.

For a prefab box it is nice, I put a sundown 12 there 600watt woofer, the lows isn't to bad it could be better, but it wasn't built for the woofer specs. Construction is top notch and it looks really nice, I would recommend if your not a bass head, and putting into a nice car. And it fits in my 2013 mustang.
