JBL Marine A754 Compact Amplifier
JBL Marine A754 Compact Amplifier
Part Number: SKU:JBL-JBLMA754AM
The JBL Marine A754 Compact Amplifier is a 4-channel marine amplifier built for boaters looking to upgrade their audio system without taking up valuable space. This Class H amp delivers 75W RMS per channel at 4 ohms (400W total) and features variable electronic crossovers, high and low-level inputs, and preamp outputs for flexible system configuration. Its compact, low-profile chassis fits tight marine installations, while full on-board protection keeps your investment safe in saltwater environments. Whether you're integrating with aftermarket or factory stereos, the Marine A754 Compact Amplifier handles both speaker-level and RCA inputs for seamless compatibility.

Features & Benefits:
• Compact low-profile chassis with small overall footprint, ideal for marine installations with limited space
• Variable electronic crossovers (high- and low-pass, 32–320 Hz, 12 dB/octave) on front and rear channels for precise system tuning
• Input Level Control adjusts sensitivity from 200mVrms–4Vrms (low-level) or 1Vrms–22Vrms (high-level)
• Full-range preamp outputs allow daisy-chaining an additional amplifier without splitters
• Selectable Turn-on mode (DC/REM) for compatibility with low-level or high-level signals and battery protection
• High and low level (speaker-level and RCA) inputs for integration with aftermarket and factory marine stereos
• Balanced Differential Inputs for low noise and distortion, with resistance to engine noise interference
• Full on-board protection against shorts, high temperature, overvoltage, and undervoltage with LED indicator
• Class H amplifier design for high output and minimum current draw
