Mrd_m301 not working after unpluging head unit

SOURCE: Correct settings

I am not familiar with your amp, but any amplifier performs best when the output stage effective resistance exactly matches the load resistance. So, read your 15" subs and find out number of ohms, then set the amp to that number. according to your amp's specs: if you have 2 ohm speakers, you can draw 350 watts from your amp. so purchase 2 ohm speakers
