Could alternator noise/ground loops damage your speakers/subwoofers ?
I'm hearing a little bit of a hiss/noise in my subwoofers but you barely hear it!
if I pause my music and put my ear allmost against the subwoofer, I can hear it a little bit.
Could this damage my subwoofers ?
I think I know where the noise comes from. I installed my amplifiers on a self-made metal rack. So I guess the amps have multiple grounds. Could that be the problem ?
