Alloy Series 2,100-Watt 4-Channel Class AB Amp


Be cool and stay cool with the Autotek Alloy Series 2,100 Watt 4 Channel Class AB Amp! Featuring a compact design while staying cool, the Alloy Series delivers unrivaled clarity to subwoofers and speakers. Included with built-in electronic crossovers and high-level inputs, Autotek Alloy models easily tie into OEM (factory) audio systems that do not offer RCA output as well as ones that do. Easy, under-seat self-installation will have you enjoying Alloy levels of clarity in no time. This Alloy 4 channel amp can be used 4 channel stereo, dual stereo bridged, stereo + bridged mono, and dual bridged mono modes.
