very loud noise from speakers all of a sudden

[orangecounty1 10+ year member]

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 SHIT TON of engine noise. sounds like my speakers are turbo'd or something lol. i mean its LOUD.

im like shit, 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?

This is what happened when Trey and I installed the RSD's. It could be the HU, but it is likely the wiring on your speakers....I'm sure you and Robin will figure it out but I remember it being Trey's fault and all the equipment was fine.

My 880 was noise free for over a year, then the dreaded whine showed up. Grounding the RCA's eliminated about 90% of noise, so I can live with that. It's the nicest POS HU I've ever owned //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif
