    Unfortunately due to a miss wire, the headunit in my car ended up in smoke. I have since pulled the headunit out and traced the fault to be the amplifier unit in the headunit. I Removed it, put the headunit back in the car and everything else works great.

    What I am hoping is I Have got 2 Fusion 2channel Amplifiers installed in my car, which i would like to wire into the head unit. But it may not be as simple as I was originally hoping.

    Reading the specs on the dead amplifier component, its input impedance is 100KΩ.
    The input impedance on the Fusion Amplifiers is 20KΩ

    I am unsure of the output impedance of the headunit, but I assume i need to make the new amps impedance match the old amps impedance to keep the headunit happy. Is there an easy way to do this?

    Note: Reason for keeping current headunit is that it is factory to the car, and also controls the air-conditioning so swapping it out is not an easy option.
