Atrend 12JL01DV 12” JL Audio Dual Vented Subwoofer/Speaker Enclosure Compatible with WO & W1 Series Subwoofers. Made in USA

I've been dabbling in car audio for nearly 32 years and this is by far the best pre-fab box i have ever owned. It fits my two JL Audio 12w3v3-2 perfectly and the bass they produce on 1200 watts wired down to 1ohm is amazing. Do yourself a favor and avoid the "sorta kinda fits" pre-fabs if you have JL subs and buy this. You won't regret it. I replaced a single Qbomb box which was way too boomy and smelled terrible with this and a second sub and it was worth every penny.

the measurement where the speaker goes is cut half an inch or more wide, so I had to put the screws on the side almost lying down.My speakers are 12-inch JL Audio W7In the photo it says 11 inches where the speaker goes, I didn't measure it, but I think it's more than 11 inches, because I put my speaker in and there wasn't enough wood to screw and I put the screws almost flat and I don't know if in that position go withstand the impacts of my JL Audio.
