I have one of these in my VX, had it for about 6 years myself. Couldn't ask for a better sound from such a small space with low cost. It's not going to wake up the neighborhood, but you will feel it and it's got great range.

It's also extremely tough. I have mine mounted facing up into the ceiling as it seemed too "loose" bass-wise pointing into the side. The grill is heavy duty and I've tossed all manner of stuff on top of it and never had an issue.

It's well worth the money as an easy, self-powered and tough solution.
