Remote wire/12-volt question

I just had a brainstorm, since the remote wire is only hot when the key is 'ON', could I not run my remote wire for my aftermarket amp coming off my 12-volt cigarette lighter? This way it sends the signal to the amp to power on when the key is turned.

 

if the remote wire youre talking about is the thin gray wire going into the stock head unit, it turns on when you turn the key to "ACC".

 

or if you wanted I think you can run a wire to the battery and just put a switch between there somewhere. I wouldnt recommend doing this though because you always risk leaving the amp on and thus having a dead battery.

 

Yeah I know how the wire works, but instead of going for the remote wire to the radio, can I not just use the wire that goes to the 12-volt to turn that on. Wouldn't it be the same remote wire? All it is doing is sending the signal from the truck to the amp telling it to power up. Cause i noticed the cigarette lighter only comes on when the ACC is on.

 

well i just wired up my alpine amp just a couple days ago to my stock head unit. I just used the remote wire running into the stock head unit. Its a thin gray wire. I just tapped into that and it works perfectly. Whenever my headunit comes on, my amp comes on. Let me know what you plan on using.

 

I think I am just going to go to the head unit. Since I have always done it that way. Did you use a Converter Moto?

 

No, I just used the speaker level inputs that came with the amp and tapped into the rear speaker wires coming out of the head unit. I'm thinking about getting a nicer head unit. I probably won't do this for awhile though.

 

What about your RCAs?? They can't come from the factory radio

 

What RCAs? I'm not using any at the moment. I guess im kinda confused about your question.
