Okay, so I hooked up my ipod to both of the amps through a mini pin/RCA and no noise. Soooo, must be either the HU or the RCA's I've been trying. As much as I hate to do it, I may reroute one of my better RCA cables that was run from the helm where the eq was to the port side compartment to hook it up to the HU and then to the amp and see if that makes a difference. If it does, then its the RCAs that I have been using to troubleshoot creating the noise and/or the HU. If it is the HU, should I try rewiring the HU completely or am I out a HU...? and in this case i would be out two HU's since the other HU I tried was also creating noise. I'm crossing my fingers its the RCA cables here, since the HU is basically brand new.
