The new ARC Series of amplifiers are the most technically advanced and best-equipped amplifiers ARC Audio has produced to date. Featuring the latest designs from Robert Zeff, the three new ARC Series amplifiers represent a bold step forward in how consumers and retailers perceive mobile amplification. The ARC Series Amplifier Family includes three primary 1000 watt foundation models sharing a common high-pressure die-cast aluminum heat sink with a rough-grain black anodized finish and CNC-machined accents. The amplifiers feature integrated mounting feet in the corners of the heat sink and include plastic hex-head trim caps for a finished look once installed. Known for their computer-controlled forced induction cooling solutions, the new ARC amps draw cool air in through vents at the ends of the heat sink. That cool air passes over the power supply switching and output devices and is exhausted through an opening on the front edge of the amp. The onboard micro-controller controls the cooling fan speed to keep the amp quiet.
