JBL 4 Channel Marine Amplifier
JBL 4 Channel Marine Amplifier
Part Number: SKU:JBL-JBLMA1504AM
The JBL 4 Channel Marine Amplifier is built for boaters and water enthusiasts who want serious power without worrying about salt water and corrosion. This Class D amp delivers 900 watts of total RMS power while staying stable at 2-ohm impedance, and its conformal-coated circuit board and stainless steel connections are engineered specifically to handle harsh marine environments. Whether you're running 150 watts per channel at 4 ohms or bridging it for 450 watts per channel, the Marine A1504 gives you flexible configuration options backed by an LED power and protect indicator to keep tabs on your system.
