I want to install an amplifier to my factory head unit. I have already installed a AUX RCA input. What i want to know is that if i install a RCA audio output for an aftermarket amp, will that interfere with the RCA AUX input that i installed? Help please.

 

in the stock head unit of an 03 there is no aux out put. unless your hu is different from mine.

 

This is it. HILO PAC AOEM-HON20 Amplifier integration interface for Honda vehicles OEM-1 with a vehicle specific harness plugs into the vehicle\'s wiring and offers a 4 channel RCA audio output for adding aftermarket amplification. Provides full range audio outp. It plugs into the HU

 

Should be able to use both. The HON20 is basically a LOC with turn-on. It uses different wires dorm the AUX input.

 

ok thanks a lot for the help
