Music power in a sleek package The Audison SR 6.600 six-channel amplifier's sleek extruded aluminum chassis houses an efficient source of power that'll give a boost of 85 watts RMS to each of your front and rear speaker's dynamic impact while sending up to 185 watts each to two subwoofers to improve bass. Audison D-Class Technology lets them produce a small and efficient amplifier featuring high power, high-fidelity frequency range, fine bass tuning, and almost universal connectivity to aftermarket or factory systems. It'll work in your system This amp is a great match for aftermarket receivers, and you can also hook it up to almost any factory stereo using Audison's Universal Speakers Simulator in the high-level input circuitry — which can handle up to 100 watts per channel. To make things even easier, the amp can automatically turn on when the high-level inputs are used. It'll work with your speakers and subs The onboard variable crossovers have very wide frequency ranges to clean the signals for a wide variety of different tweeters, midrange drivers, and subs. You can set up an SR 6.600 to power a pair of high-performance speakers with 260 watts RMS each from bridged A and B Channels while sending up to 600 watts RMS to a subwoofer from the bridged C Channels. There's a variable bass boost on the C Channels to help you tune your sub to sound its best when the amp's set up that way. And an optional VCR S2 wired remote volume control is also available for the subwoofer channels.
