so I have the whole system wired except for the amp on/off lead that is supposed to go to the deck
my deck is a panisonic cq-c700u and im not sure where to install the lead
the operation instruction manual and the system upgrade manual for my deck are both completely useless for finding how to do this

can anyone tell me how I can install this wire?

 

the manual doesn't tell you which lead is the remote turn on? That's strange. Anyway, as said above, it should be a blue wire that powers up to 12 volts when the deck is turned on. That wire connected to the amp's remote turn on input will trigger the amp to tun on when the deck is turned on.
