Are there any reputable shops near your house? You need a little help. For one thing don't use the bass boost. Ever. And don't adjust things like the gain while the music is "blaring". If I were you I'd make another thread and see if maybe there's someone near you that could give you a hand. Your subs are 600 watts a pc. by the way. Under powering them isn't going to be a problem but at the same time I think you might be expecting to much out of the amplifier and pushing them to hard. Someone had said you can't blow a sub underpowering it. Yes you can if clip the shit out of it....
