Infinity BassLink X 10" Car Subwoofer

I drive a Volvo S60. The bass response was okay, but it wasn't what I really wanted. I didn't want to install a whole new stereo because I like my dash the way it is, plus I don't have to worry about break ins for a factory radio. This Sub mounted right in the trunk without having to give up much space at all. It looks neat, the guys at Circuit City did a GREAT job of mounting it. I get a tight bass response, not the rolling bass without any real definition. It sounds great. I really couldn't be happier. It interfaces with my factory stereo just fine. If you're looking for more bass response and want a simple yet extremely effective solution, this is the way to go.
