DD Audio 300w 4 Channel Amplifier - Designed & Engineered in the USA Overview The new SS amplifiers are the latest in high speed, high current class D designs offering high power and superior sound quality in compact footprints. The classic DD AUDIO style heat sink is used in this upgrade for max cooling with 50% more side wall thickness than industry norms and extra long fins to increase surface area. All major components have been upgraded; 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 not only tangible, but audibly apparent. The SS4.500 is a 4 channel amplifier delivering a minimum of 125 Watts per channel from a mere 30 square inch footprint. This versatile, high speed, class D design can drive full range components and subwoofers through selectable high pass and low pass crossovers. These super small amplifiers are the ultimate combination of precision sound quality and installation ease.
