New Speakers - Polk DB6501?

RonRizz,

I just bought these RCA cables Monster MPC I202 2C-4M Low Noise 2-Channel Car Stereo RCA Cables (4 meters):Amazon:Car Electronics
In hopes that I can get rid of that high pitch sound. My current set of RCA's that are going to the amp for my component speakers is running on the passenger side which is also where my power wire is. (Maybe this is where it's picking up all that "junk")

I'm going to run these new monsters along the drivers side which also currently has my RCA's for my sub amp. Hopefully this will work. Only concern is that I don't know how I'm going to squeeze another set of cables through the "side skirt" by the seat. From what I can remember it was awfully tight.

Prior to changing them out, try this........
With stereo OFF, disconnect rcas from amp running components. Turn stereo on, and see if noise is still there. If it IS, its coming from the amp (ground issue) and not the cables. If its NOT, likely your cables are the culprit.
Turn stereo back OFF, and reconnect rca cables at amp, and disconnect at Radio. Turn back on. Noise? if so, its your cables for sure. if not, your getting noise at your radio (change that ground)
Basically, what were doing here is working our way up the chain, and isolating each individual component one at a time. Its the best way I know of to determine where noise is being introduced into the system.
