I connected up my amp, and speakers. there's a whistle noise coming from the
speakers, as I accelerate.. is this alternator whine? Is it caused by a
ground connection? if I re-ground my amp to another place, will it stop this
noise?

also my front speakers dont sound the best. Their inifinity reference 5.25
or something along those lines, their hooked upto a audiobahn 4601t amp. The
speakers are in the doors, with about a 1cm gap around the speaker to the
door hole... do they sound crap cause it isn't flush with the door?? not air
tight?? how can I fix this?/

any help much appreciated
