Ive noticed over the years that some stereo companys have power turn-on wires in EITHER blue or blue/white......bastards. It threw me for a loop last time I did an install for somone...I was lookin at the amp dumbfounded.....turn on lead was blue/white, but no amp power....traced grounds....power.....fuses.....everything checked out ok.......WTF!?!?!?!?......out of curiosity I jumped the power to the power turn-on on the amp.....fired right up......the lead was unbroken all the way back up to the head unit.....so I switched the turn on wire to the blue wire on the HU wire harness....Bingo!!!!
But in most cases, HU harness power turn on is Blue/white stripe. just thought id share my horror story
