Learn how to install the BOSS Audio MC470B amplifier on your motorcycle. Step-by-step wiring and mounting tips for reliable handlebar audio.
Quick Answer
Install the BOSS Audio MC470B amplifier by connecting power, ground, and signal wires, then mounting the amp and speakers securely. Follow the steps below for a clean, weather-resistant setup.
Why the MC470B fits motorcycle audio
The MC470B is a compact Class D amplifier with Bluetooth audio streaming and IPX-5 rated speakers, making it a practical choice for handlebar audio. Its small footprint and adjustable brackets simplify mounting on handlebars or frame rails.
Before starting, note that the IPX-5 rating means the speakers are weather resistant but not submergible. Plan the mounting location to minimize direct water exposure, such as under the handlebar or behind a fairing.
Installation Steps
- Disconnect the battery: Always disconnect the negative battery terminal before working on electrical components. This prevents shorts and protects the amp. Check that the battery is fully disconnected before proceeding.
- Mount the amplifier: Use the adjustable brackets to secure the MC470B to a solid surface like the frame or under the seat. Ensure it is not exposed to direct water spray. Test that the amp is firmly mounted and does not vibrate loose.
- Run power and ground wires: Connect the power wire to the battery positive terminal with an inline fuse, and ground the amp to a clean metal chassis point. Use appropriately sized wire for the amp's current draw. Verify the ground connection is tight and free of paint or rust.
- Connect signal and speaker wires: Connect the audio signal from your head unit or Bluetooth receiver to the amp's input, and wire the included 3-inch speakers to the output terminals. Match polarity (+/-) correctly. Double-check all connections for polarity and secure fit.
- Set volume and power controls: Use the in-line volume and power control to set the initial volume level. Start with the gain low and increase gradually while playing music. Listen for distortion and adjust the gain accordingly.
- Test Bluetooth and finalize: Reconnect the battery, power on the system, and pair your phone via Bluetooth. Test the audio and ensure all mounting points are secure. Confirm that the Bluetooth connection is stable and the audio is clear.
