Maximum efficiency, from stock electrical systems, is the aim of the SS1100. Coming in at over 1100 Watts RMS under 1% THD, it can drive single, dual or even triple subs to high output levels. Sharing the same architecture as the other full range, high speed, half bridge SS amplifiers, the over-spec power supply delivers the strong impact that low cost full bridge designs fall flat on. The new SS1100 is the latest high speed, high current class D design using name brand state of the art devices and large capacitor banks yielding 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. When every watt and millimeter matters, the SS1100 delivers the bang.
