Hey.

I've noticed that when the amp is on i can hear the power current going through (sounds like a turbo whine lol). As the car revs higher so does the whine?

Anyway to stop this? I bought a line filter and attached it to the remote wire (wire wasnt big enough for power wire so that was the next best place) but it did nothing to help?

Any info would be appreciated.

Cheers

Check grounds, don't run power feeds near any electrical gear (including parallel to the loom inside the car), etc.

Its a BA falcon. The power runs down the drivers side then under the back seats into the boot, would this be affecting it? As far as i know the ground is ok, what should i check for with the ground?

With the grounding, make sure it's grounded directly to BARE metal and not over paint. I had the same problem in the Hilux so I got rid of the paint then grounded it directly onto the bare metal and it's fine now.

or it could be the rca i had this prob with us audio rca's changed them now its all good
