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 |

Just looked up the datasheet for the 15" in my cabinet and it has a range of like 20-2,000 hertz with a 99 db sensitivity, so that'd explain things. That and how it's constructed probably differs a little as well. I was thinking the ranges might've been different but why it didn't register at first I don't know, I blame no sleep over the last few days.
Well great mystery solved. I have a nice older 12" DVC Rockford Punch I need to get around to using, though it's a lot more than what I'd ever need as I think it was 500W a coil at 4 ohms. -------------------- 2001 Miata LS 5-speed
