Well I own 3 of these subs and tell you they hit really hard i have a mtx 91002 pushing all 3. The amp is to big for this sub but it still does the job every one looks a me when I am driving and some people gets really pissed but I don't really care that much some fools pull next to me with there systems, but when I turn my volume up they get the surprise. I really recommend this subs to anyone that like bass.
