This is one of our favorite 2-channel amplifiers. Immense power, compact, great crossover features, runs cool and is spectacular looking. This amplifier easily fits in the fairing or is tucked away in the corner of a saddlebag. With the differential signal input stage, including an extensive voltage range (200mV - 10.0V), this amplifier works equally with factory radios and aftermarket units. The super-efficient design of this amplifier allows very high levels of clean output with minimal demand on your bike's battery and charging system.
