JBL MA1000 - High Performance Mono Subwoofer Marine Amplifier, 600 watts RMS x 1 at 4 ohms, Max Power 2000 watts, Frequency Response: 25-320 Hz, Class D amp Technology

The JBL marine A1000 mono subwoofer amplifier delivers 1000-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 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 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 amplifier features variable electronic crossovers and bass boost circuits allowing for precise system tuning and performance.
• Low noise and distortion: The marine amplifier 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 amplifier from shorts, hightemperature, overvoltage and undervoltage. An LED indicator is provided to let you know when one of these conditions exists.
