so i got a kenwood kdc-x696 hooked it all up everything seems to operate normal except i have no sound i hooked the harness up the best i could as per the instructions but it really doesnt say which wire to hook the Pcont wire up to im pretty sure thats the problem because with out it the amp wont turn on and if the amp dont turn on i have no sound right? i also have 3 left over wires in the harness 2 orange 1 blue the orange are labeled dimmer and dash illumination but the deck lights up fine so do i need them and the blue wire is currently connected the Pcont wire but like i said i have no sound everything else is matched to its corresponding color black to black red to red etc NEED HELP!
