I got a JL audio rd1000 i set the gain until the cliping light came on with a 50 hz test tone no subwoofers hooked up then backed it off until the light went out like the owners manual said to do but when i hooked up the subs and started playing it the clipping light would flash on from time to time i backed it off to where it wouldn't light up at all my question is was the light supposed to flash on sometimes or did i do the right thing by backing it off either way i love this amp definitely worth the money
