Power wires don't induce noise in signal wires (RCAs), but crossover/ignition wires can.

Passive crossovers wouldn't radiate any significant noise.
Or cause any significant magnetic / capacitive coupled noise.

i disagree with you any power source that has a magnetic field can induce noise and i know this first hand. when my RCA's got to close to my power cables i would get alt wine the second i moved my rcas (by hand just lifting them) it stopped.

no update yet fellas.. rain has stopped me.. but will do so once it stops.

I mentioned this earlier:

(You have to fix the CAUSE of the problem, or you'll burn up a LOT of money.)

IF the amplifier isn't grounded properly (bearing in mind things like CHASSIS metal is needed to complete the circuit, and that PAINTED metal is insulated metal), then rather than simply not powering up, there are opportunities in that circuitry where the amplifier will "find" ground, through circuitry that it's not supposed to. Very, very, very commonly, this happens as the amplifier finds ground throught the negative shield on the RCA cables - back to and through the head unit preamp section.

So - you use HU #1, and the preamp section eventually burns out.

Sure - the HU has a problem. That doesn't mean the HU IS the problem.

So - you install HU #2, and of course the preamp section eventually burns out on that one.

It makes sense.

You HAVE to identify, and fix, the ROOT CAUSE of the problem, or HU#3, and HU#4 etc. will all go out this way.

How about if you describe in very graphic detail how your amplifier is grounded?
(and that's assuming that you don't have any processors in between your HU and amplifier - if you do, we need to know how those are grounded as well)
