Noise In Speakers?

[duct_tape123]

I've done everything possible to get rid of this damn noise, but to no avail. Radio is a Kenwood 438U, amp is a kicker ZX350.4. With the truck on it has noise with everything hooked up(Radio-RCA-Amp); and with just RCA's plugged into the amp, but it goes away when I unplug the RCA's from the amp. It has a good ground, and no shorts on the speakers. Ive used an iPod connected straight to the amp and there is no noise. I've replaced the RCAs and the noise is still there. I have laid the RCAs over(not run under the carpet) everything and connected straight to the radio and there is still noise. Could it be the radio? The amp?Help me before I pull all my hair out!!

Not being a smartass but it shoud be obvious man, you connected your iPod = no noise, so what does that leave, has to be the radio man.

I tried grounding the RCAs, tried new ground for H/U, tried new ground for amps, nothing worked. But what doesn't make sense is that there is noise if the RCAs are plugged in to the amp but not the radio. I connected the RCAs to the amp and left the rest of the RCAs in the package and there was noise.
