okay im getting snagged in by the whole "internet brand" subs and im looking for more spl and im wondering do each of the "internet brand" subs have some sort of reputation or certain characteristics that seperate themseleves from each other or one is just about as good as another. right now im running 2 1041 type-rs and they sound pretty good but i guess i wanted more spl and i wanna get somewhat entry level pressure bass and would that be possible with 600rms into 2 subs
