[QUOTE="stereo_luver, post: 7251552, member: 580003"] I have a Soundstream VGA 800.2 Van Gogh that is Class AB but runs cool. Besides, Class D amps aren't as efficient in the upper volume levels as most people think. Ask most any tech. They drink as much power as Class AB amps when you turn up the volume. 2 X 200 RMS 4 Ohm 2 X 400 RMS 2 Ohm 1 X 800 RMS 4 Ohm Mono RUBI™ (Rapid-Use Branched Impulse) Proprietary power supply topology STACT™ (STabilized Apex Current Topology) Reduces power supply stress by 50% Trident™ Amplifier protection topology Ultra Low ESR Capacitance bank ensures rapid power delivery for dynamic peaks Continuously variable 12dB low-pass crossover (30Hz to 4kHz) IDI™ (Intelligent Distress Indicator) gives visual amplifier protection status Triple Darlington OUtput Circuitry Continuously variable high and low pass crossovers with 12 dB / Octave slope (30-4KHz) Vortex induction fan for thermal management Platinum RCA Line inputs and outputs Platinum 4 gauge power inputs Rail stabilization protection circuitry Tri-mode operation BIP™ Bias Input Protection Harmonic Bass Alignment™ Produces tighter, more accurate bass reproduction Bi-Linear selectable 2 way crossovers for amplifiers and line outs 10Hz - 50 KHz Frequency response >115dB S/N ratio >500 Damping .15V - 12.0V Input sensitivity 0.02% THD Dimensions Dimensions 15.8" L X 2.6" H X 11.2"W [/QUOTE]
