I've tried several different grounds (bolts on the car and several other grounds), my power and RCA cables are ran down the opposite sides of the car, but still I have that annoying whine.

Are there any relatively simple solutions to this problem? Would better RCA's help? I'm currently using the RF Twisted Pair RCA's.

Thanks a lot.

where are you getting power from?

CMC

Directly from the battery, and wired it behind the ECU box into the cabin

dpd

are you inside the ecm box?maybe noise is from ecm?try rerouting.also what gauge wire are you using?

CMC

I used 8 gauge wire for the amp and yeah, my wires are inside the ECM box.

Maybe I'll try rerouting the power line. But where else can I go from the cabin to the battery?

dpd

if you look where the hood release cable is you should see a block off plug near the cable.you could use that and SEAL it very well to keep water out

CMC

Thanks...

I'm probably dating myself, but I remember doing this many years ago on one or two stereo installations.

Might try a stereo shop or (ahem) Radio Shack.

If so, maybe this will help:

Also, are you getting the noise regardless of the source?

Good luck.<ul><li><a href="https://forums.audiworld.com/audio/msgs/13471.phtml">https://forums.audiworld.com/audio/msgs/13471.phtml</a</li></ul>

Sounds crazy, but try this. Got to Radio Shack and get a ground loop isolator and try that.
