I wanted to build a custom middle console sub box in my 09 silverado ext. cab. I was curious if I would be able to fit a JL Audio 12w7 or a JL Audio 13w7. The reason why is because the sub boxes that fit under the rear seat just isnt enough for me. I like alot of bass and very loud music. and a custom middle console box is the only other way where I dont have to sacrifice my rear seats. I want to get as much possible without doing a blowout system that takes up the whole back of the truck. If anyone has something similar or knows if this will work it would help out alot thanks!
