    Upon re-reading your posts, is it possible that you did not ground the amplifier properly before powering it up? If so, the amp may have sought ground via the shield of the RCA cables and damaged the preamp section of your source unit.

    Well i have a 2nd battery and i hooked the amp up directly to the 2nd battery pos to pos neg to neg. i am not sure if this is a bad thing or not. and i hope i did not mess up my new head unit :/

    This can be one of the most difficult problems to track down and eliminate. Keep in mind, your RCA cables are likely run along the body of the car under the carpet . . . the body being the return path for all things electrical. The fact that they are on the opposite side that the power wire is run could either be helping or counting against you.

    Really obnoxious noise is usually quite easy to eliminate. That typically indicates a problem with a component. Your explanation above is somewhat unclear. Did you say that you unplugged the RCA cables from the INPUT of the amplifier AT the amplifier and plugged your iPod directly into the amplifier and still had noise? Or, did you mean that you plugged your iPod into the RCA cables at the front of the vehicle near the deck?

    Be careful unplugging and plugging RCA cables with the amplifier powered up. In some cases, the input section of the amplifier can begin to oscillate with nothing plugged into it. Bad things can happen as a result . . .

    yeah well i plugged in the ipod directly into the amp not using the rcas and there was no alt whine witch makes me believe that there is no issues with the amp or speakers. so my only 2 things past that is the rcas or the head unit itself. so to rule out where my reas were ran my friend had a brand new set of top end rcas. so i ran those just over the seats not under the side trim ( just a 1 min test because he wanted them back) and the alt whine was still there. witch makes me believe that the rcas are ok. so now i'm at the head unit.

    well the rcas and power wire are ran on the other side of the car. and i have now tried 4 different rcas with the same conclusion. so it must be the ground. but i have been looking and can not find a good place to ground it.. i have a 2004 VW jetta and if know about newer vws everything is hidden or covered ect.

    so i really don't know where to ground it.

    OK so today i was going to install my 4 chan amp and new door speakers till i got punched in the face by alternator wine.

    So i have ruled out my speakers and amp by hooking up a iPod straight to the amp. now as soon as i plug in the rcas it wines really bad and if i unplug the reas from the head unit and only plug them into the amp it wines a very small amount but it is still there but i could live with it.

    So i tried grounding my rcas to the head unit with no luck so i am confuse and pissed off at this point. what can i do next.??

    I know the main source of wine is coming from the HU and a small bit from the rcas ( also the rcas are top of the line knu and i also tried my RF twisted)

    any help will be helpful!!!! AHAHA
