Conclusion: I have two in a small enclosure behind my rear seats and they kick very hard with the limited power I feed them. I wish I could give them a larger enclosure but space there is not much space behind my truck's rear seats. Very happy with product.
Conclusion: I was intently on a quality sound for my extended cab chevy truck. Its important to get a matched box for the volume of air the sub moves. With a medium quality mono amp this single sub rumbles my entire truck with zero distortion, and clean, sound. No rattles, or fuzzy noise.
