Got to hook up an inverter for wiring an amp to the factory stereo, need to know the right and left hand side source wires to hook the inverter to. its an 05 f-150. any help on knowing?

 

okay on an update i just said screw it and spliced two jumper wires off each wire hooking into the back door speakers. now next question on that comes to this. it gives me a pos and neg for each left and right source on the inverter. both of the speaker wires have power on them. do i hook one to each, or one to both and then ground it or anyone know how?

 

One of the wires should be positive and the other should be the ground. I'm not sure on your paticular wire colours though.

 

Speaker wire info on your 2005 STX
