I have a 2002 with a plain factory stereo, no bose. no monsoon, but I was wondering if the amp turn on wire is still run through the car? I am changing the headunit and have the Pac C2R-GM32R And it has a connection for an amp turn on wire, so I was thinking I could use that wire to turn on my sub amp I will be putting in later, instead of running my own wire? Not sure if since there is no factory amp, there would be no factory turn on wire? I suppose I could check myself when I am installing the headunit, but thought maybe somebody would know? Thanx

Moved to Audio for better visibility.

If I remember my Monsoon amp, it used the radio'* power antenna wire to turn on. That is how I currently have it set up anyhow.

Does your car currently have a power antenna? If not, you may already have the wire going back to the antenna. I believe it to be green.

I have a windshield antenna as far as I can see. I do not know if it has a power booster or not, and I do not know what color that wire is for it. I know that the PAC interface has the blue with white stripe going to 3 different things, it'* split 3 different times on the ribbon harness. So I should prolly just connnect the blue wire with white stripe cuz it cuold potentially turn on 3 different things? I would still like to know if the amp wire is still there with a car that has no factory amps, again I could check, but I wouldn't know where to find the end of it, or what color it was to start with...
