DESC: The new Riot series from Boss Audio combines the hot look of a shielded aluminum heatsink with the cool performance of Mosfet circuitry. Go ahead and hook up a huge system, the Riot series can handle it with built-in low- and high-pass crossovers and selectable 18 dB bass boost. This great looking amp also includes speaker-level inputs, tri-mode capability, and remote subwoofer level control. All Riot series amplifiers feature extruded aluminum heatsinks with black end panels and top cover.
