alternator noise on sound system....
My sound system used to sound okay....sometimes it still does. just need some input before i start checking it this weekend. let me explain. i have an alpine amp to power the main speakers and an mtx amp to power my sub. it's been workin fine till the past couple of weeks. there are times when i hit a road bump, all of a sudden i get this annoying alternator noise. sometimes it's not "hearable" if i turn the volume up. but there are times when it's pretty bad. yet when i hit another road bump, sometimes it disappears, sometimes it doesn't. what should i check for.....good ground on both amps....make sure they're tight? should i ground both amps at the same spot? i guess i should get a ground loop isolator from radio shack as well, right? any inputs....suggestions! silverknight...any advice? thanks! george

ground loop isolators are junk. dont get one, they dont fix the problem they only cover it up.
if you are hitting a bump and getting engine whine, check all your grounds it sounds like something is loose.
also, i hope you ran your rca's alone, and speaker and power alone? rca's pick up noise very easily.
