This sub surprised me so much! I have it powered by a Soundstorm EV1500M 1500W amp in a custom-built carbon fiber box. I originally put it in a cheap box that wasn't a good fit for the sub, but once I built my own box with a friend that was made specifically to the exact air volume and tuned properly to the sub, my life changed. For how inexpensive this sub is, it hits extremely hard! My friend even got one after I purchased mine, because he was so impressed! It hits the deep lows well, and sounds extremely good with bass rolls. Great sub!
