ok ive recently installed 4 new speakers and a amp, both the speakers and amp are "response" brand or other wise the jaycar electronics brand.
amp: http://www.jaycar.com.au/productView.asp?ID=AA0453&form=CAT2&SUBCATID=1028#4
ive got static coming out from my channel 1 output, its their as soon as the amp is powered up and goes away after a couple of minutes of driving.
ive swaped my outputs and inputs around, this is how i discovered its from channel 1.
i have taken the amp back and had it replaced with a new one only to have the same noise out of the same channel
the static is compleatly independant of the volume level, and sounds like a off tune car radio.

any one know a way i can reduce or eliminate the static?
