Power supply voltage / fuse 11 ÷ 15 VDC / 1 x 30A. Operating power supply voltage 6.5V ÷17 VDC. Idling current 1.6 A. Idling current when off 0.03 mA. Balanced high-noise rejection input speaker-In (for OEM head units) and RCA-In (for After-market head units) inputs.
ART (Automatic Remote Turn-On/Off) automatically turns on/off the amplifier when the OEM head-unit turns on/off (can be enabled/ disabled, with Speaker-In inputs).
