buzzing nise through speakers while engine running

JAXXX · 09-22-2004

i have a 95 mustang gt with mac460 sound system i get a humming nise coming through the rear speakers i replaced the spark plug wires and i still get the noise sometimes 2 it seems like the base in rear speakers sounds like crap... both of these problems are intermittent tho im wondering maybe 1 of the amps may be going out ? any help would be appreciated

something's wrong with your ground.

Check your ground for corrosion.

i forgot to mention itdoes go up with engine rpm i tried to remove the rear black box with the amps and all that i removed the 4 bolts but it didnt wanna drop down (i didnt have much time to mess with it at the time) i take it the ground i need is under the speaker box?

kscoyote is right. It will be the ground from your stereo or the ground on your amplifiers. Check and make sure they are good secure grounds. You can test a ground with a multi-meter.
