Conclusion: I got one of these when I bought my truck and switched it out for a pair of L5's. These blew so I am temporarily running one of these off of a Rockford T20001 BD. I had it in a sealed enclosure, and it would pop when the bass got turned up even a bit. I thought I would swap it out to a bigger vented enclosure to remedy this, but it's not much better at all. It's fully powered, and I tested it with an ohm meter, and there are no voice coil problems.
Conclusion: Solid clean sharp bass! My two tens spit out those higher frequencies with no stress. I love the CVX version of Kicker subs. Very durable just give it the recommended 500-600 watts rms and you will think you have 12" subs. Great value and ill be ordering more of them!
