JBL Marine A5055 Compact Amplifier
JBL Marine A5055 Compact Amplifier
Part Number: SKU:JBL-JBLMA5055AM
The JBL Marine A5055 Compact Amplifier is a five-channel marine amplifier designed for boat owners who want serious power in a tight space. This Marine A5055 delivers 760 watts RMS of Class AB+D power with flexible connectivity—both high and low-level inputs work with factory or aftermarket stereos. Its compact low-profile chassis fits easily in space-limited installations, while variable crossovers, bass boost, and phase control let you dial in your system perfectly for the water.
Specs & Details:

| Dimensions (W x H x D) | 360mm x 51.3mm x 180mm (14-3/16" x 2-1/16" x 7-1/8") |
| What's in the Box | Marine A5055 amplifier, 4 bare wire-to-RCA adapters, six 30A ATO fuses (3 installed, 3 spare), remote bass control module, 16.5' remote control cable (RJ-25), 2 self-tapping screws (M3 x 15mm), 4 mounting screws (M4 x 53mm), owner's manual, two JBL stickers, 1 logo badge |
Features & Benefits:
• Compact low-profile chassis with small overall footprint to fit in space-limited installations
• Variable electronic crossovers and bass boost circuits for precise system tuning and performance
• Input Level Control adjusts sensitivity between 200mVrms–4Vrms (low-level) or 1Vrms–22Vrms (high-level)
• Phase Switch changes input phase to inverted or non-inverted, especially useful for the subwoofer channel
• Class AB+D amplifier technology delivers 760 watts RMS with high output and minimum current draw
• High and low level (speaker-level and preamp) inputs for compatibility with aftermarket and factory marine stereos
• Balanced Differential Inputs ensure low noise and distortion, reducing susceptibility to engine noise
• Full on-board protection against shorts, high temperature, overvoltage, and undervoltage with LED indicator
• Includes RBC wired remote for convenient volume adjustment from the driver's seat
• Selectable Turn-on mode (DC/REM) for compatibility with low- or high-level signals and battery protection
