Ok so i finally install my system about 2 weeks ago. everything with it has been amazing. got a xenon 1200.1 and 200.4 running an uberwoofer 2 acro mids and 2 lga tweets. Everything has been working great i go to work everything works fine. I get out and whenever i turn the music up alittle high my right speaker cuts out and i get terrible static like some1 is scratching a record. and now theres no sound comming out of my right mid at all. so i start messing with the RCA's to see if i can solve the problem or find out what it is and i pull out both the acro rcas and the static goes away. So i put in just the left just the right and then switch the rca's and its not the rcas cause when i put in just the left side rca in the left side of the amp eeverything sounds perfect no static except im not getting sound out of my right speaker. If i put just the right 1 in the right amp side i get the terrible static. I think it may be my HU or something? i dont think its a blown speaker because when i plug it in i get static out of both sides really bad. I have a pioneer 860mp. its about 2 years old now thou. help me out.

try pluggin the left rca into the right input and see if you have no static then on your right speaker.

You might have alreayd did this and i just mised it reading through.

sounds like the headunit

i did do that. And i believe i still got terrible static. and no sound threw the other speaker. .. i know this model has a terrible "ground loop" problem. could this be the problem?

you've eliminated bad driver and bad amp channel.

you now need to switch RCA's inputs at the HU.

IF the static SWITCHES sides again...BAD RCA.

If the static still comes out of the same side when you switch, BAD HU.

don't know. find the WHAT first, then deal with WHY.
