[QUOTE="MellowHype, post: 7771756, member: 640052"] So, I wrapped some wire around the rca inputs on the HU, and the noise was gone... for 10 seconds :@ So thats not the problem. I think my next step is the head unit ground. Yeah im going to give the HU ground a go next, i looked at the connections at the back of the HU and the found the ground, what do i do? replace it with the same thickness wire and just ground it to a more solid point? does it matter how long the wire is? Ive ran double sheilded rca's down the other side of the car and the noise is still there. Didnt seem to help alot :/ Ive done a bit of reaserch, and it seems to be a common problem with the CDA 117. People say they have the same pops and whining sound. Also, when i wired my second amp, i used the 'daisy chain' to wire remote to the second amp, this wouldnt be a problem would it? The amp thats powering the comps is a straight wire from amp to HU, so i dont think this would be a problem. One thing i might, or could try, is using the 4awg wiring powering my Kicker EX1000.1, and try it in the Alpine MRP-F600 powering the comps. [/QUOTE]
