Amp

[madmike1]

I have a problem with 4 of the channels on my amp. they cause the speakers to make a high pitched wine. it is the front and back channels. the sub channels are still working. does anyone know how this was caused and if it can be fixed?
thanks

Have you run all of the cables together ??
If you have that will create interference, you should always run the cable to your amp away from the power lead etc.

I have ran the cables together yeh, but it was working without interference. is that what interference sounds like? i have never had any ICE in my car before so dont know?

yes it is,your getting the alternator sound assing from the power lead to the phono,put the power lead down the opposite side of the car to the others

 

[madmike1]

lol it was working fine with them together now it aint?

if so check your earth as why would you suddenly get interferance if you aint moved the cables

 

[madmike1]

its not interference. i have just moved all of the cables apart and it is still causing the same noise. does this mean there is a problem with the amp? if so then what problem?
thanks

check your earth as well, and make sure you've sanded the metal down enough.
