REVIEW – As I continue to remodel and upgrade my home office/Studio to be a warm interesting and creative space, I have been introducing things like Steampunk shelves for an added industrial look, and I have been looking for unusual items to give me the feel I want. When this KEMIMOTO Midnight 40B 16” 2-Speaker Louder RGB UTV Sound Bar with Built-in Battery was offered to the gadgeteer team for review, no one selected it because it seems that none of us has the type of vehicle it is designed for. I decided I would find a way to use it as an indoor speaker to enhance my office while maintaining the ability to go portable with it at any time. Here is a glimpse of my journey.

What is it?

The KEMIMOTO Midnight 40B 16” 2-Speaker Louder RGB UTV Sound Bar (Built-in Battery) features over 200 dazzling lighting modes that sync to the beat, fade in and out, flash, and jump,  300 watts of power, Digital Signal Processing (DSP) technology to ensures distortion-free sound reproduction without any interference from engine noise.

Installation, Setup

The KEMIMOTO Midnight soundbar is designed to fit on the roll bar of an ATV or other type of outdoor vehicle including watercraft. Since I decided to try to make it fit in my home studio, I found a 90-degree Wall Mount Bracket on Amazon and mounted it to the bottom of an existing shelf. I then adjusted the included quick-release bracket to face the right direction and mounted it to the bar. The speaker easily connects to the quick-release bracket. For charging the built-in battery, I connected the included cable to the DC in port, and the other end to a DC 12v 10a Male Cigarette Lighter Plug. I plugged the DC plug into the DC port on my EcoFlow Delta 2 Max Power Station which provides 12.6V DC and up to 10 amps. This meets the specs of the speaker. I also connected a 3.5mm stereo to RCA L/R audio cable between the audio out of the speaker and the subwoofer to send a signal to the subwoofer.

The KEMIMOTO Midnight 40B 16” 2-Speaker Louder RGB UTV Sound Bar with a Built-in Battery performs well. The sound is great for everyday listening and will be great when outdoors. The ability to add a subwoofer works well for my in-house adaptation. The light show and lighting options are nice and the companion app does a great job of displaying the true versatility of the lighting. The control pad works well and the Bluetooth and audio cable connectivity are rock solid.


The following video shows how I mounted the speaker in my home office/studio and provides an overview of how it works:

What I like about the KEMIMOTO Midnight 40B 16” 2-Speaker

  • The great build quality
  • The nice rugged look
  • The built-in battery
  • The customizable light show
  • The nice sound it produces
  • The app
  • The quick-release mount to make it portable
  • The comfortable carrying handle

What needs to be improved?

  • Although designed for outdoor/vehicle use, I wish it had a standard AC charging option to recharge the built-in battery for portable use.
  • I know I am not using it the way it is designed to be used, but I still wish that it had a remote control so I could turn it on/off while at my desk (wishful thinking, that’s all)

Final thoughts

The KEMIMOTO Midnight 40B UTV Sound Bar with a built-in battery is a nicely built, rugged speaker with a nice rugged look. While it is built for vehicle and portable use, I am happy that I could adapt it for my in-house studio and still keep it portable. It sounds nice with the subwoofer connected and as a portable standalone speaker. I like it.
