OK so just recently with no notice every time i start my car the rear speakers pop. only the rear lower speakers. (i have the mach 460 in a 97 gt) Its kinda annoying, i havn't noticed any sound diffrence in the speaker. but i can't really tell all that big of a diff between small distortion and none. so it doesn't bother me. But my question is what can i do to get it to stop. I hate every time i start my car. POP goes me rear speakers, its embarising for me...
