DESCRIPTION

Even though it's the smallest of the Thunder mono amps, the Thunder311D is ready and willing to deliver some serious bass. At 4 ohms, you get 155 watts RMS. Hook up a 2-ohm load, and the output doubles to 310 watts! A built-in low-pass filter (85 Hz at 18 dB per octave) eliminates the need for an outboard crossover.
