This bass package combines two B2 Audio RIOT 12-inch subwoofers with the compact DD Audio SS2000 Class-D monoblock amplifier. Together, the subwoofers handle 2000 watts RMS while the SS2000 delivers 2000 watts RMS at 1 ohm, creating a properly matched high-output system.

Each RIOT subwoofer features dual 4-ohm voice coils. Wire the two coils on each subwoofer in parallel to create a 2-ohm load per subwoofer. Connect both 2-ohm subwoofers to the SS2000 in parallel to create the recommended 1-ohm final load.

The RIOT subwoofers combine heavy-duty 3-inch voice coils, 18 mm Xmax, 240 oz motor assemblies, and high-current 8-gauge push terminals. The SS2000 delivers the power they need through a compact aluminum chassis with 0-gauge power terminals, adjustable filtering, ZVL inputs, and an included remote gain control.
