PowerHouse407 Posted May 25, 2012 Report Share Posted May 25, 2012 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!!!!

SmallTruk Posted May 26, 2012 Report Share Posted May 26, 2012 Bad RCA's, RCA's too close to power wires, or bad ground on HU Those are what come to mind first based on what you said. Quote Link to comment Share on other sites More sharing options...

PowerHouse407 Posted May 26, 2012 Author Report Share Posted May 26, 2012 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.

snafu Posted May 26, 2012 Report Share Posted May 26, 2012 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 . . .

snafu Posted May 26, 2012 Report Share Posted May 26, 2012 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.
