I cant get rid of this hissing noise!

hey...how are yall doing....

i installed a new headunit, front speakers, rear speakers,  tweeters, and subs in my car and i have one 2 channel amp pushing the subs and a 4 channel amp pushing the other speakers....i asked yall how to get rid of this hissing noise i get from all of the speakers (not the subs) and i was told not to run any speaker wires along w/ the power wire....i had the speaker wires for my right fronts and tweeter running on the passenger side along w/ my power wire but i moved the speaker wire to run w/ the speaker wires from the left speakers and rcas all on the driver's side....i did that and the hissing noise is stil there!

its funny b/c the  hissing noise hisses w/ the way i accelerate ...and also when i turn on my blinkers...its always hissing but u can hear the pitch get higher? it gets really annoying ...any ideas on how to fix this? thanks

do you drive a Honda? they are notorious for having noise problems...as pressure just said, separate everything as much as possible and make sure all your grounds are solid...its almost advisable to run a heavier ground than positive lead...do you have an aftermarket alternator? is it a re-wind? sometimes when shops rewind alternators for higher amperages they dont upgrade all of the parts and noise suppression isnt really thought about, so you get an alternator that will really crank out the noise...

let us know how that goes...

I owe a Honda Civic and an Acura Integra. I have never had any noise in any of my installs. Always use Qualtiy Equipment and always run your wires like the above post and you will be find.

sounds like the gains on your 4ch amp are probably wide open - if they are, try turning them down and see if that helps
