Activation wire help

[PenguinsAudio 10+ year member]

I have a car that has a stock radio in it and i was wondering if it was even possible to use an amp. i was going to take the inputs from the rear speakers and use that for the imputs to the amp, but i didnt know what to do for an activation wire. i took out the head and it had these wires running out of it- Bat, Acc, Ill, Park, Rf-, Lf-, and mute. are any of these an activation wire? if not is there some way to run an amp without an activation wire?

Thanks for helping a wiring noob out

Tap into the ACC wire. That will turn the amp on when the key is on. If you want the option to be able to turn it off with the car on put a manual switch on the wire as well.

if you dont want to do that, you can pull out your stock radio as well. it should be the red wire. tap into that.

You can also tie into the cars ignition switch. It takes quite a bit more work, but it will turn on and off with the key. IMO its the best route if you dont have a remote to tie into.
