    ok, i went in, regrounded the amp which didnt help anything , but thats OK it needed to be done anyway, was going to reground the head unit and monitor but then decided i want to swap their position, id rather have the monitor up high and the dvd player down low to improve the angle on the monitor (it will only go straight vertical if its mounted in the cd changer slot becuase of the slope of the dash) so ill reground them during the move... picked up some 10' twisted pair RCAs made to reduce noise, theyve got a 3rd wire on them, which im assuming is ground, do i need to do anything special to ground that properly? do i ground both ends? this is the first time ive really done a 'high end' installation so cheapie RCAs usually do just fine

    thanks guys!

    oh yeah, and i also checked where my speaker wires are running, only the fronts are near anything that would give me trouble (drivers door runs for about 2 ft with the power wire and pass. door infront of the TOD computer), looks like the main problem is RCAs

    DONE

    put the dash back together, cd player in the lower slot, monitor in the upper

    no more whine either! new RCAs helped some, new ground helped some (thanks biju) then i added an inline noise filter in the power to the HU and that seemed to get rid of the rest, during heavy acceleration its just barely audible, not at all when theres music playing

    yeah, after doing some more research i found out they were for remote turn on, so i just taped them off, the upgraded wires definately made a difference though
