09' Adding subwoofers
 

I am going to be adding a couple Rockford P2's that I have laying around. I plan on just using a line output converter and hooking them to the stock system. Anyone know what color wire to spice into for the remote wire? Also, is there anything else I should look out for when doing this?

Kinda crude but I always just ran a wire from a fuse that gets power with the ignition like the radio fuse. You just need a small current to turn the amp on. Some amps, not many though, have current sensing so theyll come on when they sense voltage in their inputs.

there is a remote turn-on output from the head unit, but it is sometimes missing from the HU harness.

if your vehicle has Active Noise Cancelling (ANC) you will need to defeat this feature.

I'm not sure if it does or not. I will have to look. Do you know what color the remote turn-on wire is if it is there?
