So one day my amp decides to stop giving power to my subs out of nowhere. Its not on or in protect mode. Its a Hifonics Brutus BRZ1200.1D and the hifonics lettering on the amp is illuminated still but power and protect isnt. In the manual it says that its not getting adequate voltage through the remote source to turn the amp on. I already jumped it from a 12v source but it still does the same thing. I checked all the wiring, the grounds fine, and no fuses are blown. What could it be?
