Grounding RCAs?

[Cpyder 10+ year member]

I have a high pitched squeal coming from my speakers only when the RCAs are connected to my amp. When I use a Y-adapter and my ipod, it's fine. I've read that this problem is almost always caused from the grounding of my RCA cables.

How to I go about grounding them?

I really don't want to take out my head unit because I have to remove my dash and it's a pain in my a$$.

Can I wrap wire around the negative part of the RCAs at the amp and run that wire to the chassis?

Can I use the same ground as I do for my amp ground on the chassis?

Are your RCA'a run next to your amplifier power wire for more than about 18 inches?

Either your RCA's are pickin up noise due to being to close to your power wire or you've got a bad ground connection at the HU. The solution is to move the RCA cables away from the power and check your ground connections.

No, they run down the right side and the power cable runs down the left side.

Then either you have a faulty ground connection at the HU or your RCA's are damaged.

How does that happen?

Yeah, I don;t blame you for not wantting to take the HU back out. The entire dash has to come out in order to get the HU out.

Is that a rehtorical question? Answer = EMF noise induction.

Tell me about it. I've done it twice. Not that hard but it takes forever!!

Are you sure you've got a good ground for your amp? Grounding RCAs is usually a band-aid.

Are you using the Bluetooth Adapter for the Alpine? If you are then that is your problem...VERY common problem with the new alpines.
