Did not think it would work well….use with 4gauge wiring, and it fantastic! ive always had issues with systems but I cant get this one to go into protection mode with it maxed out running DUAL 15" subs in a ported box in my crown Victoria. I bridged it to monoblock and it does not hesitated to bump. nor does my electronics suffer and I have not even hooked up my capacitor yet. absolutely recommend!!!
