DESC: The Riot GT series from Boss Audio combines the hot look of a shielded aluminum heatsink with the cool performance of MOSFET circuitry.

With a built-in low-pass crossover, selectable 18 dB bass boost, and included remote subwoofer level control, you can be sure your subs will pound loud and clear. All Riot GT series amplifiers feature extruded aluminum heatsinks with black end panels and top cover
