I'm just looking for some information on the 10" 100watt Bazooka subwoofer that's offered for the tC. If anyone out there owns one, how much better does the stereo sound with it, versus without? Also, is there a built in amp for this sub, or does it draw its power from the HU? This sub states it has 100 watts "maximum power", which leads me to belive the amp is under powered. I was thinking of using an external amp with the sub, as power is cheap and pleantiful. I know most people go for their own custom box with bigger woofers, but I like the appearance and sleakness of the bazooka sub, and its natural "blending" with the car.
