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

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.
