Speaker high pitch noise

[2fast4all]

I'm wondering if anyone can figure this problem out for me. For the past....month or so Ive been hearing a semi-high pitch noise from my rear right speaker. I cant tell if the speaker is blown or not, though I know I hear a little engine noise when I drive. It hear the noise when I turn the engine on, I do hear a slight alternator whine but very low. It doesn't make the noise when I turn to ACC or the ON position...

I'm guessing its the RCA's? I am using 10 year old monster cables.. so those might be degrading? I know the grounds to my amps are fine. Ive noticed if I turn on the car with the music on, unplug the rear channel RCA's and plug them back in, the noise is gone.

Here is my hardware.

Speakers: Kicker KS600 6''

Subwoofer: Rockford Fosgate P3 12'' Sub

Tweeters: Sony XS-H20S

Head Unit: Sony CDX-GT630UI

Amp: Pioneer GM-D7500M (Sub)/Kicker DX 200.4 (door speakers)

Distro Block: Monster 4 to 8 gauge (4 inputs)

Install bay 4 gauge wire

Monster RCA's (10 years old)

Various speaker wire

Any input would help me a lot, thanks!

RCA's or ground issues are your rcas and your power wire running next to eachother?

[2fast4all]

All the wires: power, speaker, RCA's are running on one side, why? Because its easier on me to troubleshoot...

Run your rca's away from everything. It could help reduce the noise or get rid of it. if not double check grounds to make sure it's a good solid connection along with it being a metal to metal connection(sand off all paint).

Bass race is right you need to seperate your power wire and turn on wire from the rest of your cables because of electrical noise. If that doesnt work then get a volt meter and test for resistance in your rcas
