POWER ACOUSTIK D2-600 Demon 600 Watt 2 Ohm Stereo Amplifier - Red MOSFET Power Supply with Pulse Width Modulated circuitry make up each DEMON amplifiers power supply. MOSFET transistors increase durability and longevity over bi-polar counterparts. Variable 12dB Crossover filters out frequencies that could cause damage to speakers, or that subwoofers can't play via 12dB/octave slope high pass, low pass, & subsonic crossovers. High Level Inputs let you integrate DEMON amplifiers with factory radio speaker outputs. Connect the speaker outputs of the factory radio to the color coded high level inputs. 2-Ohm Stable Class A/B Full Range, 200mV-6V Low Level Inputs, Tri-Mode Capable, Three-Way Protection Circuitry, 4 ga. Power & 8 ga. Speaker Terminals, Regulated Power Supply Extruded Aluminum Chassis features Brushed Aluminum Finish with Red Anodizing
