So I made a sealed box that takes up the inside of the spare tire well and has a false floor baffle flush with the rear seats in the down position. The volume on the interior is around 2.85 cubic feet and there is cushion foam lining the floor pan in the back. The whole box is bolted down to the spare tire tie down hole and that is also the ground point I'm using for the amp. Here's a picture of it.
 Looks great and sounds great, but at certain frequencies I get a buzz from my plastics in the back. I believe it's also buzzing the bumper and license plate bezel (not the license plate itself since it has a rubber "anti vibration" frame. Anyone have a good way to quiet that crap down? Lol |

It's also a matter of enclosure, if it's not properly tuned for the woofer then you won't get optimum performance. That's any speaker though. The largest car audio sub I've used is 12" but in PA systems I use 15" woofers all the time and the good ones never have trouble keeping up with arpeggiated bass lines. One would think there'd be a 15" car sub as well that could keep up since in function car systems aren't too different from PA systems, and that's to accurately reproduce the sound.
