The Memphis MXUSBA is a round panel-mount connection port designed to add accessible AUX and USB connectivity to a marine or powersports audio system. It provides a clean mounting point for connecting compatible devices rather than leaving loose connections exposed around the dash or console. Its compact round format is suited to installations where space and weather resistance are important.
This accessory is intended for boats, UTVs, ATVs, and similar applications that need a conveniently located audio connection point. A covered port arrangement helps protect the connection area when it is not in use. The IPX6 rating supports use in environments exposed to water spray and the elements.
The MXUSBA includes a 3.5 mm AUX input and male RCA outputs for integration with compatible audio equipment. It is a signal-connection accessory, so final sound quality depends on the connected source device, receiver, and audio system. The direct wired layout is useful for systems that need a dedicated external AUX connection.
Memphis designed the MXUSBA around a 1-inch mounting diameter, allowing it to fit a properly prepared 1-inch mounting hole. The visible outside diameter measures 1.25 inches for a compact, finished appearance at the panel. This makes it suitable for dashboards, consoles, switch panels, and other flat mounting surfaces with adequate rear clearance.
A 3-foot attached wire length provides flexibility when routing the port to a radio or other compatible device. The unit combines USB and 3.5 mm connections in one panel-mounted assembly, reducing the need for separate ports. It can be used as part of a new marine or powersports audio build or as a connectivity upgrade for an existing system.
Key Features
- Marine And Powersports Design: Built for audio installations exposed to outdoor-use conditions.
- IPX6 Rating: Supports protection against powerful water spray.
- Sealed Cover: Helps shield the port area when closed.
- AUX Input: Provides a 3.5 mm connection for compatible audio sources.
- Male RCA Outputs: Connects to compatible RCA-equipped audio equipment.
- Compact Panel Mount: Fits a 1-inch mounting hole with a 1.25-inch overall diameter.
Design & Installation
The MXUSBA uses a compact round, panel-mount design with a sealed cover for marine and powersports use. Its IPX6-rated construction is intended to help the connection area withstand water spray. The small 1.25-inch overall diameter gives the installation a neat, integrated appearance.
Install the port in a properly sized 1-inch hole in a suitable panel, then route its 3-foot wiring lead to compatible equipment. The 3.5 mm input can be used with an appropriate AUX source, while the male RCA outputs require compatible RCA connections in the system. Confirm rear-panel clearance, cable routing, and the connection requirements of the receiving equipment before installation.
