If the amp can’t get the power it needs form your alternator and battery, it will not be able to produce its full output. Your ARC Audio amplifier will produce full output for longer than other amps on the market today. If the Voltage or Current drops too low, even our amplifiers will drop below their rated output.
Speaker Level Input Pigtails All ARC Audio X2-Series amplifiers include a set of high-level speaker input RCA pigtails. These pigtails include a resistive voltage divider network to reduce the signal from a high-power source unit or factory amplifier so that it can be used with the differential Inputs on your X2-Series Amp.
