Hey! I have had speakers, amps, a sub, cap, and deck put into my car a few years ago. Recently my speakers have been giving me some trouble. Some of them work regularly and others will only work when i turn the volume up. They then stay on until i hit a bump or shift, then go out again. Anyone have any suggestions on what may be the problem? I'm not one of those fix it ppl when it comes to car audio. I got them installed by Futureshop and haven't had problems until now. I don't really want to bring it somewhere and have to pay someone to fix them if it happens to be an easy fix that i can do. I'm handy but just don't have the knowledge about audio and cars. If anyone could help, that would be great! Thanks!
