Has anyone bought and used the Infinity BassLink powered subwoofer in their car? Any thoughts/reviews? I just got a new (used) car and gave my old sub to my girlfriend (her car needed bass, too!). It was so freaking big, I couldn't use my trunk to its full potential. I need to get a new sub and this is small, comes highly rated, etc... But I want to know what fellow bassists think about it. ... or other recommendations for a slightly compact sub for the car.
