Subpar

In terms of overall sound quality/performance, the XXX's are definitely amongst the Sub elites. As for the asking prices and power feed from your car, ehhhhh... Just put it this way. There are subs out there with quite an emulating performance that don't cost nearly as much.

Agreed. MTX subs are nice, but choosing to dwell outside of your typical electronics mainstream stores, there are MUCH better subs, for cheaper prices and more reliable builds out there. What's with all the outside covering? It's like they're hiding the resistor.
