The KS500.1Mini 500 Watt 1Channel Amp from Arc Studio is a compact amplifier that has been designed for small vehicles and/or motorcycle applications. The KS500.1Mini employs Full Range Class H Architecture that significantly improves efficiency without compromise to the sound quality. The KS500.1 Mini uses a patent pending Auto Sense Turn-On circuit that offers significant improvement in reliability. No more will the amp unexpectedly turn off in the middle of a song. Instead of relying on the music to supply enough signal to turn the amplifier on, ARC Audio's new design detects the BTL IC (Chip Amp) used in the majority of stock head units and amplifiers. To further simplify OEM integration, the KS 500.1Mini 500 Watt 1 Channel Amp uses a fully balanced input stage between the speaker and RCA input. Simply plugging your stock speaker wires into the RCA's will supply a perfect clean signal to the amplifier and turn it on.
