Well i bought my d3 off ebay new, everything was good until i pluged in my rca's. I get horrible alternator whine like sound when the car is only in the ACC mode. Its in a 2005 altima Se-R. I have tested with a friends working amp and its not the amp or the speakers. all the other equipment i have worked great in my other car about 2 months ago.

I messaged pioneer too see about warrenty since it was made in feb07 i might still be in the manufactors warrenty..i dunno tho.

What might it possible be? bad connect to the d3? or just bad d3? everything else works prefect tho.

thanks, steve

did you run the rcas on the same side of the car as the power wire? if so, change that--gotta run rcas and power wires away from eachother of youll get alt whine
