its alt whine. move power wire away from rca's. and what head unit is it?

9 times out of 10 the induced noise you are experiencing is the fault of a bad ground connection.

What kinda gear are you running and what size wiring brings it all together?

move power wire away from rcas.

Only if you want to for the cosmetics of it. Otherwise assuming everything is hooked up right and your interconnects aren't faulty this makes no difference.

Also, make sure that you have solid ground points.

On your computer....try grounding the computer case (from a screw on the outside of the metal case) to the same ground as your amps (im assuming you have a carputer). You can just run a wire from the case to that ground point.

unplug the rca's from the amps and go for a drive, if you still have alt whine I'd say it's the amps needing regrounded. If the whine goes away reground the HU and DON'T use stock wiring for the ground... that should fix it...

It's a JVC KD-AVX1, and it didn't do it in my other car //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

I'm using 4 gauge power wire spliced to a clarion apx200.2 amp, due to the size and type of terminal, on a JBL C608GTi component set.

I am referring to my cars main computer.

I noticed some of my speaker wires run right beside a main harness when going into the very back of the car... maybe i'll try moving them. I will attempt a headunit reground this weekend. working 2 jobs kills my stereo time //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

thanks for the suggestions!

I agree with Prowler. 9/10 times it's a grounding problem either at the headunit or the amplifier.

Keeping the RCA's away from the power wire is a myth.

same thing happened to my buddy. i would bet on the ground wire also.

I had the problem and it was neither the RCA or the grounding of my amp. It was actually a faulty amp. Something internal must of been messed up and when i changed the amp and left all wiring the same it fixed the problem. But im sure mines a rare case.

Definitely a possibility. Having something faulty with the preamp outputs on the headunit is a possibility aswell.

But the majority of the time it is due an issue such as grounding.
