Your choice...

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

I bought the single 12 inch box for my rockford fosgate P3, the box makes my sub hit very clean and hard. The only problem is that Sonic Electronics ships the sub box with NO protection. I recieved the box with 3 dings in it but sonic couldnt help me out. So its hit or miss...

12 inch subwoofer enclosure

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

It looks well made. I haven't installed it yet. I plan on installing a Rockford Fosgate T0 12inch sub with a RF BDCP1500 pushing it. Cutting the amp down to about 750 watts. I can't wait to hear how it sounds. Judging by past Attend enclosures I've owed, it should be a ground shaker!!!

Atrend 12SQV

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

Id have to give it a honest for stars only because of the subwoofer I'm running needs a bigger box. Great for something that's putting out consistent thousand RMS at 35 to 55 Hertz.But for me I'm currently running 1600 rms.

Decent box for the price

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

Gets the job done. Not the best looking thing in the world but I am pleased with it. For 70 bucks I couldn't pass it up and I am glad I didn't. Still holding up after a year of almost daily use with a Kicker CompVX in it being pushed pretty hard.
