I've been searching the whole internet ihave 03 Accord v6 i have the disc platter or gps whatever it is in the trunk i got a head unit with navigation climate control ask that installed aftermarket. I no longer needed the one in the back. I disconnected it but for some reason my remote wire only powers one amplifier from head unit. Even with a relay with relay it won't power either amp without relay only one amp n trying to t tot it same result only one amp. I know the amp is good and i know my wiring is good as I've t tapped n ran other things from one source to multiple sources and have some different schematics to make sure it's not my wiring. I don't feel like running more wires from to back n since i don't need that unit anymore i want to either run the accessory wire or remote wire that turned that unit on and use it to power my second amplifier or relay it for other things also. What wire or color wire would this be because ican't find the proper diagram for the Accord that with v6 navigation.
