which would be louder? i already have two 15" SX but only one of them is hooked up...never had time to build another box...how much more of a difference will there be by adding a second 15" SX with a seperate amp...
MT's theres really no specifications cause theres so many configurations (thats what re says) and most ive heard someone put to it was 2500 rms but im not to sure with that sub if u get another SX it would add +6 db ... twice the bass
