[quote="Scarrell"]welp alot of you know that i got this problem fixed by switching hu's.. well guess what? its back.. this time the sub is all staticy and crap.. this $hit is really pissing me the F#ck off.. tomorrow im going to re-do the entire wiring and see what happens.. :help: :sad017: [/quote]
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 [b]and through[/b] 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)

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

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.

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

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

[quote="solacedagony"]Crossovers can induce noise into your signal wires, but I don't think anything can happen by putting power/crossover next to each other.[/quote]

I might be wrong, but I have always heard not to but the crossover next to power or ignition wires. I don't really see a problem having them next to signal wires.

Crossovers can induce noise into your signal wires, but I don't think anything can happen by putting power/crossover next to each other.
You could try checking all your ground's resistance with a multimeter, just to make sure they're good (although, from what I understand, not a dead-certain way to tell if they're good or not).
Let us know how your re-wiring goes and if it solves any problems.

yay for 900 posts!!... well.. im goin to relocate the crossovers today.. they are up by the firewall.. im thinkin maybe since the power wires are so close to one of them, maybe its crossing signals.. so.. we will see.

This post has 666 views as of me looking at it right now... haha

im sure, but as i said im going to be taking all the wiring out and re-doing it.. maybe its a voltage issue? i dont know.. i know when we first got the car.. the stock stereo would Always be on, it wouldnt shut off.. but mine doesnt do that.. so i dont know..
