I downsized from a pair of Kicker 10's and got this to reclaim my trunk space. Compared to that, the Cadence unit sounds like a whisper, so don't expect it to replace a full-sized box. This is NOT a "window shaker" that can be heard around the block; the goal is strictly sound quality and a little bottom end in the cabin. Even though I have a mid-sized sedan (Chrysler Sebring), this is too big to fit under my driver or passenger seat, so off to the trunk it goes. You may be better off with some high end 6x9's in your rear deck, because you may not notice this unit if you have to mount it in your trunk. But if you simply want fuller sound, this will fit the bill.
