The Audison SR 4.500 amplifier uses Class D circuitry to deliver tons of power in a compact chassis with an affordable price point. Audison completely redesigned these amplifiers to compete with JL's XD line to deliver more power, at an affordable price point, while offering superior signal processing and thermal management.
 
The Audio SR 4.500 puts out 130 watts to 4 channels at 4 ohms, 220 watts per channel at 2 ohms, and 450 watts to 2 channel when bridged at 4 ohms. This type of output is not seen in most 4 channel car amplifiers. This amp accept both high and low level inputs and has 12dB/octave variable crossovers between 50 Hz and 3.2 KHz. It offers both high, low, and all pass filters, and has a full-range pre-out if you are using another amplifier.
 
If you are looking for high output and fanstastic audio quality, the Audison SR 4.500 definitely over delivers for the price point. These amps sound great, put out tons of power, they are compact for what they are, and they have a sleek, stylish, matte-black finish.
