noise through speakers
i hooked up a system in a 96 ford escort new head unit all 4 spkeaers to a 1000 w amp and 2 12s and an 1000w amp
when i start the car o get noise through the speakers and it changes as the engine climbs in rpms i know that means i have a bad ground but i changed the ground to 3 diff places and it does the same thing every time
and i even went to a bigger ground wire and still the same result
any ideas this is really pissing me off

Could have a bad battery ground, bad ground on the 1k watt amp thats connected to the door speakers, or that same amp could have internal problems causing the noise. A ground loop isolator could help some

The problem lies somewhere in your RCA's, or the RCA input on either your HU or amps.
Could be the ground on your HU
Three things you can try
1) New RCA cables (I would try this last since it is the most expensive)
2)Ground the HU to the amp, just disconnect the groud at your HU and run a 16 guage piece of wire back to the ground on your amp
3)Ground the jacket of the RCA to the amp, just siolder a piece of wire to the jacket of the RCA's(the ground) and run it to the ground on the amp

all good ideas ill try them.......would it matter that i have the rca cables from the 12's running to the other amp? i ran it from the output on my sub amp to the input of the doorspeaker amp..other than that i have the power running on the complete opposite side of the car of the rcs cables but i do have some speaker wire running next to them
