recently installed a clarion HU. It had 1 red power wire, and 2 yellow power wires (3A, and a 15A fuse). Iv never seen 3 power wires, so i hooked up the 15A. It powers ect.. The tuner works, and powers teh amps. But the CD funcion isnt wokring properly. It says CD, and shows that it is playing, but the amps dont turn on, and obviously sound does not play out to the speakers. Any ideas why the amps shut off whenon CD mode?
