Compact footprint for space-limited boat installations
Variable electronic crossover for precise system tuning
Adjustable input level control for high or low-level sources

Class H design for high output with efficient current draw

The Infinity Marine 3004A offers a compact, efficient solution for boaters looking to upgrade their audio system without sacrificing valuable onboard space. Built around Class H amplifier technology, it delivers 400W RMS across 4 channels while keeping current draw to a minimum, an important consideration for marine electrical systems. The amplifier features variable electronic crossovers for precise tuning, along with adjustable input level control to accommodate both high and low-level sources, making it easy to integrate with factory or aftermarket marine stereos alike. For those building out a larger system, full range preamp outputs let you power an additional amplifier without relying on splitters. Balanced differential inputs help minimize noise and distortion, even at higher output levels, and reduce susceptibility to engine-related interference. A selectable turn-on mode adds another layer of practicality, helping protect your battery from unnecessary drain, while comprehensive onboard protection circuitry, backed by an LED indicator, guards against shorts, overheating, and voltage issues.
