Infinity's Marine 3004A amplifier will add plenty of muscle to your music without breaking a sweat, and it'll look good doing it. This 4-channel powerhouse delivers 75 watts RMS to each of the front and rear speakers in your boat. Into planning ahead? You could use this amp in 2-channel mode now to drive a couple subwoofers with 200 watts RMS each, then reassign it to your front and rear speakers when you get a bigger sub amp.

Compact Size
Infinity amplifiers have been engineered with a compact footprint to fit in more boat even if available space is limited.
High & Low-Level Input
Speaker-level and low-level inputs allow the Marine 3004A to integrate with both aftermarket and factory marine stereo systems.
Variable Crossover
Unlike many amplifiers available at similar prices, the Infinity Marine 3004A features variable electronic crossovers circuits allowing for precise system tuning and performance.
Low Noise & Distortion
The Marine 3004A has been engineered using Balanced Differential Inputs to ensure low noise and distortion even at high output levels. This also makes it far less susceptible to line induced radiated engine noise.
Input Level Control
When low-level inputs are used, this control adjusts the input sensitivity between 200mVrms and 4Vrms. When high-level inputs are used, this control adjusts the input sensitivity between 1Vrms and 22Vrms.
Full On-Board Protection
On-board circuitry protects the Marine 3004A from shorts, high-temperature, overvoltage and undervoltage. An LED indicator is provided to let you know when one of these conditions exists.
Preamp Outputs
Using multiple amplifiers, the Marine 3004A has full range preamp outputs allowing you to feed an additional amplifier without using splitters.
Phase Switch
This switch changes the input phase to inverted or non-inverted. This is especially helpful with the subwoofer channel.
Class H Amp Technology
The Infinity Marine 3004A 4channels subwoofer amplifier delivers 400-Watts RMS using a Class H amplifier design to ensure high output and minimum current draw.
Turn-On Mode
This switch changes DC to REM to adapt with low-level signals or high‐level signals, this is especially helpful as part of remote turn-on lead of your installation more choice. A selectable "Turn-on mode" can protect battery to avoid current drain, when you don't expect turn on your amplifier.
