Infinity MARINEM3004A High Performance 4 Channel Marine Amplifiers

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. Speaker-level inputs allow this amplifier to work in almost any system, even if you're keeping your marine's factory radio. You can use the separate high- and low-pass filters on the front and rear channels to maximize the performance of your speakers or subs.

• Low noise and 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.
