This sub is amazing. I listen to all kinds of music including rock, metal, country, and some rap, and responds very well no matter what I put on. I have it wired to pull 500watts @ 2 ohms from my kenwood KAC-8105D amp and it hits hard. It's in a .76 ft3 sealed box and it sounds very throaty. Even with it being sealed my rearview mirror is useless. Before i installed it i was somewhat skeptical at how it would sound at lower volume levels because of the extremely stiff suspension. However, even before completely breaking in it was very audible at all levels. Very pleased with this sub. performs like one at least twice it's price. Put's my brother's two 10" kickers to shame.
