Audio Systems: headunit responce error, kenwood amp, kenwood kdc

Question
I just recently bought a Kenwood KDC-MR532U headunit. i also have a Kenwood amp and a 10 mtx sub in my truck. when i turn to the radio(tuner) the amp turns on and the sub works. However when turn on a cd, the amp stays off and am getting no response through the sub. hope you can help. thanks


Answer
There are two 12v acc outs on some Kenwoods, Like my mask. blue is for amp and blue white for acc, I can't remember off hand which is which but one is on all the time the radio is and the other is for the antenna so it goes down when playing CDs in the car wash etc.
