ok, umm i dont get how u get your full potential power out of an amp when the gain is never up if u set it correctly.. so how do u even get your number of watts that the amp will actually do? and what does the head units voltage mean or do? i never got it explained to me. someone was telling me the number matters but why? but another ? is why does an amp get clipped when your new to audio and don't know what your doing and turn everything up cuz i know i did that the first time i got my 1st system. haha but im far from that now. but theres just a few things ive been wanting to know. and the guy who put my system in said my amp will not get fried because the protect is working and it wilL stop it from frying well guess he was WRONG!!
