The new SS4.1300 brings next level power to the multi-channel wing of the SS Series amplifier line-up. With nearly 200 watts per channel at 4 Ohms and over 325 Watts at 2 Ohms, these compact amps will drive pro audio and motorcycle systems to new extremes with exceptional sound quality. The SS amplifiers quickly earned a reputation for big clean power from a small package. Their high speed, high current class D designs offer high power and superior sound quality in compact footprints. The classic DD AUDIO style heat sink provides max cooling thanks to 50% more side wall thickness than industry norms with extra long fins to increase surface area. As with all DD amps, all major components are name brands; use higher current mosfets and output devices, increased power capacitors, a more powerful transformer, plus improved venting and PCB with twice the thermal capability. These new high-end mini amps are state of the art, no compromise designs yielding the best sound with unparalleled power to size ratio. The transformation is physically tangible and audibly undeniable.
