5-Channel digital amplifier will amplify four speakers and a subwoofer. The ability to bridge channels will allow for multiple wiring options and power handling ratings, giving you more options with the same quality and efficiency. This super-efficient design allows for lower power consumption and eliminates a larger power supply, allowing it to run far more efficiently with lower distortion and cutting or clipping. With a height of less than 2", it also features 4-way protection circuitry and stainless steel hardware that will not corrode, giving the amplifier longevity and a sleek and stylish look.
