Need Help RCA issue

[evilson007]

So. I Installed 2 amps 4ch and mono in my Jetta a in 2007 with a D2. worked perfect. I removed the stuff when i sold the car in november. I bought a 2005 Vw GLI and just installed the D2 when i got it. I put the car in storage over winter. I got new door speakers and put all the stuff in 2 days ago. i did a ruf install with a friend and just hooked it up and it worked awsome. the next day i cleaned up the wiring and mounted the amps and cleaned up the D2 harness and i get both alternator wine and Unit noise. like when it starts up and loads a disk its very loun through the amp. i cheaked the ground and connections and they were good. I pluged my Ipod in the rcas up frount and it sounded clear. so the amps and RCAs are good. today i used teh power and ground from the amp and cheaked to see if it was a power issue up frount and i still got the wine from the unit. Dose mean my RCAs decided to go bad when i wana use them?
