well it's nevr been metered with the american bass 100.1 but with the gay sony amps(4 500 rms amps) it did 145 in the kick but it's alot louder with the 100.1 and i would almost bet itll do 147ish... the boxes were both like 2 cubes around 38-40 he peeked at 48Hz when it was metered on the sony amps
