To integrate your aftermarket amplifier with the factory system in your vehicle using the PAC APH-CH03 AmpPro harness, follow these steps. First, locate and disconnect the White 22-pin, Gray 22-pin, and Gray 10-pin connectors from your vehicle's factory amplifier. Next, connect the APH-CH03 harness to these connectors. Then, connect the male connectors from the APH-CH03 to your aftermarket amplifier. A crucial step involves using a tone generator to identify the speakers in your vehicle corresponding to the speaker numbers labeled on the harness. Consult the wiring chart in the APH-CH03 manual to correlate each speaker in your car to the harness's speaker numbers, noting these down for reference. Finally, connect the longer loose wires from the APH-CH03 to your aftermarket amplifier or passive crossovers, using the wiring chart you completed. This ensures proper speaker connections for an optimized audio experience. Should you need assistance, the PAC technical support team is available via email or phone.
