I was trying to adjust my amp and accidentally pushed the screwdriver a little too hard which bent the mechanism back to where the adjustment screw for gain/power was straight up and bent back. The subs was bumping until that moment. So I took the amp apart to check it out and I bent the adjuster back to where it was supposed to be and nothing looked broke or fried. But still no sound and its hooked up correctly also green power light is on. Someone help please!!!!!
