I have one of these in a custom made(by me) 2.4 cu.ft slot port box in my 2004 ram hemi quad cab truck, powered by a lanzar mxa 232 amp. It hits so hard iv'e cracked my windshield and its about to knock my head liner out of my truck literally! put it in the right box and this thing will kill subs that cost 3-times as much.8 gage allen bolt wire terminals a nice touch on a sub this price, very good fit and finish, build quality is amazing for a sub this price.
this is mainly for the other review ive had numerous sets of woofers from cheap to expensive and have only flexed and/damaged the rear or front window in the vehicle twice i know what it takes to do this and one of these woofer no matter what box amp or vehicle will do this if your window cracked you had a default in the glass i had 4 of these in a in custom box in a little chevy s10 was a waste of money time and effort please be honest when you review something on this site some of us care about what we spend money on and want to help the audio community with true and accurate reviews.
kinda got a point there... I've had 2 rockford ti 15's in a ported box built to 4.6 cubes on a sundown 2500.1 amp, running at 1 ohm, and i had trouble breaking my windshied. None the less, these are good for the money. But not windshield shattering subs
