I got 2 of these in the reccomended sealed box size 1.25cu ft per sub and hooked up to a power accoustic lt 620/2 amp.. The sound quality is impressive and the loudness for the amp... but i was wondering how much louder it would be if i upgraded my amp to like a Infinity REF611A or a MTX TC4001 . Right now with my setup you can hear me with the drivers and passenger windows down coming from around 150ft fairly clearly.. how much do you think the range would increase with one of those amps sticking to a sealed box?

I like the sound quality and tight bass of the sealed but if i were to go to a ported box should i stick with the 2 cu ft per sub or what...

rule of thumb is double the power the get +3db.

no matter if the subs are in a sealed or ported box?
