whos good with ICE????

[aid]

Ok so i did my mini ICE install on sat

new sony head unit
MTX components up front
infinity 6x9's at the back
underseat sub on the drivers side
all powered by 2 amps in the back

BUT

the rear speakers have a very high pitched whine when the engine is running and it gets higher and kinda louder as the revs increase i have tried putting on a ground loop isolator on the amp in question but that doesnt help and its not the speakers because they are brand new, the cableing is also brand new

any ideas folks????

Your RCA leads running from the HU to the amps are probably suffering some interference. How have you routed the cables? Have you tried running them loose through the car before hiding them behind panels?

the rca's were put together then run behing the panels but its strange how the front speakers dont seem to be suffering my thought was alternator feedback??????
