If the UTV sound bar(https://www.kemimoto.com/products/utv-bluetooth-sound-bar) cuts out when hitting a bump, it’s likely that there is a loose or damaged connection somewhere in the audio system. Here are a few things you can check:
Speaker wires: Check the connections at the back of the speakers and the head unit to make sure they are tight and secure. If the wires are loose, tighten them and see if that solves the problem.
Amplifier connections: If you have an amplifier in your audio system, check the connections between the head unit and the amplifier, as well as the connections between the amplifier and the speakers. Make sure all connections are tight and secure.
Ground wire: Check the ground wire connection to make sure it is tight and secure. A loose ground connection can cause intermittent sound cutouts when hitting bumps.
Head unit: If the problem persists, the issue may be with the head unit itself. Check the wiring and connections at the back of the head unit and make sure everything is connected properly.
Check for damaged wires: Inspect all the wires in the audio system for any visible signs of damage or wear. Wires that are frayed or damaged can cause intermittent cutouts when they are jostled.
If you are unable to identify the source of the problem, it may be best to take your vehicle to a professional audio technician for further diagnosis and repair.
