Totally agree....I have my sub in the drivers compartment of the car and the soundstage with the sub on is many times over better than when it is off...and with the priceless parametric equalizer (the only one on the market, i'll bet) built into the unit you can tweak the system to perfection....i am driving a JL audio sub with an MTX 4244 4ch amp with the rear channels bridged into the sub, which as a dual voice coil and, thus a 2 ohm resistance, and the excersion on the driver is amazing! I think I am pushing about 150 watts through it, but it could easily take more. A class D mono amp of 350-500 watts would be just about perfect as this sub just absorbs as much power as you can give it........

the possibilites are endless!
