Your choice...
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...

Decent box for the price
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.

Atrend 12SQV
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.

12 inch subwoofer enclosure
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!!!

12 inch subwoofer enclosure (Attend)
I have owned Attend enclosures before and most of the time they sound great. I plan on installing a Rockford Fosgate T0 12 inch subwoofer. I'm using a RF BDCP1500 cut down to about 700 to 750 watts. I know the sub can take it and we will see if the enclosure can. I've had those subs in a enclosure when I first got them with the BDCP1500 and they cracked the enclosure! The box wasn't an Attend though. If the enclosure doesn't hold up, you will be hearing from me again. Happy Pounding.
