    Amp showing different DMM readings on each channel

    Alright so short and simple

    Tuning my amp gains with a DMM.

    Need 28.28 for 400 RMS per sub.

    Running 2 4ohm DVC Hifonics subs to 2 ohm load on 2 Channels on an Arc Audio FD 2200.

    I can get one channel to 28.28 but the other channel is reading 16 - 19 and I'm trying to figure out why. Maybe someone here will have some insight

    I am using a stock headunit with a LOC. (stock headunit is a double din and it sounds clean with my added soldered AUX input)

    does your LOC have any adjustments?
