ummmm yes

and the type x is not gonna like that kind of power. Find a different sub if you want to use that much power

not familiar w/ said amp... but looking at the model # is that a 3krms?

i give mine half that and thats really pushing it. 6k on 2 will not last longer than like 2min

naa there only pushing like 1800rms rated so proly not getting but about 1400 or 1500 rms to each sub, not pushing them tooooooo hard, lol

i know if i didn't have mine facing inside where i can hear it when it bottoms out my 1.5k probably would have killed it already.

yea ive dont alot of adjusting on the gain and listening, but i had them in my lil car in a small, box so now im trying to figure out the optimal sized box for em, so i can get the max outta these subs, yea im careful with the gains tho
