It should be similar to a normal amp and have a remote lead from the head unit to the factory amp. Once you find that lead you use a software called AMP_CTRL or VOLUME_AMP_CTRL. I then bought a device called a PAC TR-4. Its a small device that sends a amplified signal to the remote lead to ensure it turns on.... You then connect the other end of this device to pin #4 on your serial port. 2 other wires also come out of the TR-4, one goes to Ground and the other to a 12V source. Everytime you turn on the car, the TR-4 will wait for a signal from the serial port then turn on once the Amp_CTRL turns on pin #4 on the serial port.

Have you tried locating the AMP and looking at it? It should say what is what. The connections should be 12V+, Ground, RMT (Remote wire), and audio ports. Once you locate the lead wire (RMT) just find that same wire were the head unit is.
