got engin noise when tune on audio system
I got Pionner system and 2 custic amps and 3 subs. After I install, I got engine noise from speakers when I turn on the AC while I am drinving. When I turn off AC then the noise is gone. I check the grounding and it's good. Does anyone know how to fix the problem?

I only hear the noise with the A/C or interior fans on. My problem
was introduced with a battery relocation. However, two trips to
the shop that installed it haven't eliminated the problem. Now
they're saying it's a function of the length of the run and the noise
is being picked up from the chasis - BS. This is driving me nuts.
Thoughts?
The setup is dual 2 guage Monster Cable power cables for both + & -.
The ground is to the frame rail in the right rear of the car.
The ground point was cleaned prior to bolting down the - cables.
It's fairly heavily sheathed wiring zip tied to the fram along the
way.
Could it be that there's too much wire? I wanted to use a single
1/0 wire but they didn't have it. I tried disconnecting one of the
ground cables but the problem persisted. I'm at a loss here and will
look into any suggestions you have.
Thanks in advance!

run. We could have done 1/0 also but this should be equivalent.
I just wonder if it might not be too much wire that's contributing
to the problem. Anyhow, again, any input/suggestions are welcomed.
Also, if someone has an FSM and can tell me where the A/C is grounded
I would appreciate it. Perhaps that's in need of some cleaning too.
Cheers,

Im sorry, but I must still ask, what is it that you are running that you "need" that wire?
