ok see i need to know what is louder 4 8's or 3'10's the subs are ma audio xe subwoofers 20-800fz. sealed or ported box dont matter it will be in a single cab truck so wich will be louder and have better spl and soundqaulity?
3 10's in a ported box would be loudest, but it will be easier to put a sealed box ina single cab truck unless you want to spend some real money on a ported box for a single cab
