Infinity Reference 3004A — 4-Channel Class-H Amplifier, 75W RMS x4

The Infinity Reference 3004A is a compact Class-H car amplifier designed to install where space is limited. Delivering 75W RMS to each of four channels, it works with both aftermarket and factory head units thanks to selectable speaker‑level and low‑level inputs. Variable electronic crossover circuitry gives you accurate system tuning for improved performance. Balanced Differential Inputs are employed to minimize noise and distortion at high output and to reduce susceptibility to line‑induced radiated engine noise. Built‑in protection circuitry guards the amplifier against shorts, excessive temperature, overvoltage and undervoltage conditions, and an LED indicator alerts you when a protected condition occurs.
