well i put ears to the speakers and i have FAINT noise coming from the 6x9s and mids. when i unplug one side of the rca cables the noise gets MUCH louder and then when i unplug both it goes away ... the HU RCA's are already externally grounded i did that already to cancel that problem. like this .

i notice that when i move the RCA away from my power wire by the amp and it got more faint. is there away to filter the RCA and power wires to reduce the noise coming from the power wires ?
