temporary setup consists of a pioneer 880 that ive had for years and never had a problem with, never had to do the ghetto "grounding the RCA's" thing, etc.

knu konceptz RCA's that ive never had trouble with either.

well i took out my mtx 2ch amp the other day to cover the back of the wall in the MINI.

it was working when i took it out. i put it back in last night becuase i was driving around with no music, and i turn on the radio and theres like a loud kind of static noise and a little clicking out of both speakers.

i start the engine and theres a chit TON of engine noise. sounds like my speakers are turbo'd or something lol. i mean its LOUD.

im like chit, the mtx amp finally broke??

so first i try another set of RCA's...same thing

so i go up stairs and grab one of the rf punch45's im selling, put that in, same thing. so its not the amps, and it does it on both amps with 2 sets of RCA's, on both speakers.

so its not the speakers, rca's or amps.

maybe its the HU...im gonna stop by robins when i have time and through his 880 in and see if it still happens, if not ill know its my HU..i liked the 880 too.

but whats weird is the tweeter i have hooked to the actual HU amp, plays fine. so its gotta be something with the RCA outputs...maybe ill try the rear outs since i only tried 2 sets of rca's on the front outputs.... ideas?

Did you move any of your grounds when you took it out? I would check it again just to make sure you're getting a good ground and that it is not your issue.

ill double check when i get home today.

Honestly, that sounds like the classic "Pioneer ground issue". My 6000UB is being serviced at this time because of that. Improper install on my part caused a short and boom, horrible ground noise. Grounding the RCAs in the rear helped, as well as using quality RCAs, but it was quite irritating.

yep, be careful throughing your friends 880 in, you will probably make his have the same issue as yours.

good idea.

i always heard of this issue with pioneer, but ive owned about 4 differnt pioneer decks over the years, and ive had this 880 for at least 2-3 years now, and never had a problem. i love the HU but damn, i dont want to ghetto ground my RCA's lol.

has anyone called and complained to pioneer?
