I have my receiver settings for subwoofer which starts at 0, I have it set at 3. My EP2500 set the EP2500 GAIN @ 11 o' clock for both channel 1 and 2. Each channels power dual 15 inch subwoofers. This is the same settings that my brother had when he owned this subwoofer set up for 3 years. I've had it for 2 years now. So a total of 5 yrs without any issue until last night. Even now, when I set the EP2500 GAIN at 0, the light still lit that it "clip". Have I damaged the subs? Or the Amp? Any help appreciated.
