it is as simple as soldering a 1k ohm resistor on the remote lead going to the factory amps. I say this because if you ever add an aftermarket amp you will need to give it the full 12v turn on. If this does happen all you will need to do is connect the new amps turn on to the decks turn on before the resistor and you can turn everything on...... Well I will not guarantee you can turn everything on, there will always be some guys will just not like you no matte what you do

 

Thanks. I like simple.

 

Yeah same here that helps alot. Thanks
