Okay so I blew one of my sa-8's when I had them in a trunk car. I just reconed the blown one and put it back in the same box, only this time it is behind my seat in a truck. The reconed sub will bottom out on music that the other sub doesn't bottom out on. When I rest my hand over it this stops the bottoming. I also notice a slight rubbing/rattling sound on some notes. Not a blown sub rattle sound but it is there nonetheless. Any idea why one sub will bottom while the other one doesn't? The only thing I can think of is it has something to do with the four small holes drilled that I used to run my 10 gauge speaker wire through when it was in my old car. There are no air leaks around the sub gasket.
