About: JBL MA600 600W RMS Marine Monoblock Amplifier 

The JBL marine A600 mono subwoofer amplifier delivers 600-Watts RMS using a Class D amplifier design to ensure high output and minimum current draw. Speaker-level inputs allow this amplifier to integrate into almost any system, even one using your marine's factory radio. You can use the low-pass filter and variable bass boost to maximize the performance of your subwoofer and enclosure, while a phase switch ensures that the bass will blend well with your full-range speakers.

Compact size
The JBL marine A600 amplifier features a low-profile chassis and a small overall footprint to fit in more vehicles where available space is limited.

High and low level input
Speaker-level and low-level inputs allow the marine A600 to integrate with both aftermarket and factory marine stereo systems.

Variable crossover and bass boost
Unlike many amplifiers available at similar prices, the JBL marine A600 features variable electronic crossovers and bass boost circuits allowing for precise system tuning and performance.

Low noise and distortion
The marine A600 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 A600 from shorts, high-temperature, overvoltage and undervoltage. An LED indicator is provided to let you know when one of these conditions exists.

Phase Switch
This switch changes the input phase to inverted or non-inverted. This is especially helpful as part of system tuning based on the enclosure type and location in the boat.

RBC wired remote
The RBC wired remote is an easy installation and can be mounted for convenient volume adjustment from driver's seat.

Class D amp technology
The JBL marine A600 mono subwoofer amplifier delivers 600-Watts RMS using a Class D 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.
