Sealed box, wired to 2 ohms, 800 watts each and I only had 700 going to box, like new. Played for a short time and needed more. Fits great under rear seat in Ford Raptor SCREW... definitely fit other vehicles. Box is 49"lx12"dx6-1/2"h to top of (perfect) grills. STL, MO 63121 Shipping can be done @ buyers expense, but this thing is heavy.
