I pulled out my subwoofer today as it was making to much noise at high volumes. I run my front component set with my 4 channel amp, so i was thinking of fitting an aftermarket sub either in 6.5" or 8". I unscrewed the sub and there seems to be enough space for an 8" if i cut out the existing frame which the 6.5" was on. But the main sound problem is ofcourse the sidewall which vibrates. So it would probably be best to cut out the part which covers the sub. Anybody done something like this? Will the original sub housing be ok for this?
