i personally used the 1200w version of that amp, the A1300HCT
i managed to get a BNIB one for like 130 bucks.....and i still felt ripped off
my LANZAR 1200D did not only put out MUCH MORE bass (maybe because it actually did RATED RMS POWER), but barely go warm, the audiobling you could cook eggs off pretty much it got so hot, all same setup..... seriously, like stupid crazy ****ing hot...... they're inefficent, and overrated, and this is the exact same series of amps in question.
their subs can hit, but every bahn ive ever seen or was evened asked to listen to has gotten ridiculously hot on the cone after like 20 min of playing, sometimes less. they can get loud, but they seem like the blow very easily, and also have shitty SQ, even in sealed box's.....
for the money, you could get quality that will take a shit daily on that bahn crap......and that's from expirence....
