The Infinity Reference 3004A four-channel car amplifier delivers 75 W RMS per channel to the speakers. In bridged mode, it can be used with two subwoofers. High-level inputs also allow it to be connected to the car’s factory radio. The separate high- and low-pass filters for the front and rear channels are adjustable from 32 to 320 Hz.
Class H design combines a total output of 400 W RMS with low power consumption. The protection circuitry safeguards against short circuits, high temperatures, overvoltage, and undervoltage, while an LED indicator alerts you when any of these conditions occur.
