I have one diamond m3 15"
THIS THING KICKS ***
i've prob got about 400 watts rms going to it in a 2 cu ft sealed box, and it is lound and very clear. I listen to rap, techno, alternative, punk, radio, whatever, and I love this sub! sounds great with metallica, nelly, nirvana, my parents jazz, and talk shows.
with a 1200.1 amp that would rip **** up.
