    Posted by on 26th Jan 2020

    I just installed this to a single 3000rms 15" psi hp subwoofer ran it at 1ohm with a 10f Rockford fosgate power capacitor and the power draw from the amplifer is far less than I expected it sounds amazing the only issuse I have is the bass remote knob light is insanely bright it lights up my whole interior and hurts my eyes no job but the amp is amazing and this is bye far my favorite setup.
