I have a db drive dual 600w max sub box and an okur 1000.1 amp, I have had this same setup for about 2.5 years. Recently the amp had been going into protection mode I checked all the wires, fuses, connections, and for corrosion, but it kept going to protect. I played the amp by itself for a few days and it was fine. Then I connected the subs back and it fucked up again, then I just connected one sub and its been playing fine. Does anyone know what the problem could be?
