Nissan 370Z Forum - jikhead's Album: Custom Sub-Box IN Spare Tire
The cubic space in my box ended up being a little short on the minimum recommendations for my speaker, but it still sounds fine. It did sound a little weird and off, but after sticking the poly in the box, that seemed to address the weird displacement sound I was getting. Still, an 8" shallow sub instead of a 10" is what I should've gone with. I also took some foam and raised my hatch liner up about an inch so that it's not directly sitting on the subwoofer.
