How to Install the VOLT® OHM 4.1 Bluetooth Outdoor Audio System

July 9, 2025 No Comments
By VOLT ® Lighting - July 9, 2025

In this article, you will learn how to set up the VOLT® OHM 4.1 Bluetooth outdoor audio system. Use this system to bring your yard and other outdoor spaces to life. Designed with the DIYer in mind, VOLT® OHM features hassle-free installation – no electrician is needed, and no cutting or splicing is required. The direct plug-and-play connections reduce installation time to less than an hour. This outdoor audio system can be installed in five simple steps:

Step-by-Step Instruction

STEP 1: Set up the Amplifier on a Flat Surface  

The Bluetooth amplifier is powered by high-quality chipsets for consistent connection, superior range, and effortless connection. Place your amplifier in a weather protected space. It is important to keep the amplifier in a dry area to ensure performance and longevity. 

STEP 2: Lay Out the Main Cable Where You Want Sound Coverage

Proper cable placement is crucial because it determines the location of your speakers. The T-connectors are 12 feet apart to help you effectively position your speakers. Outdoor stereo separation is best at about 8-10 feet apart. If you want to expand your system in the future, a well planned layout will simplify this process. 

STEP 3: Install Outdoor Speakers & Adjust Angles

It is important to plan your layout and make a mark where each speaker will be placed. A ground stake is included for mounting. The speaker arm adjusts 150 degrees and locks securely in place, minimizing sound spillover into unwanted areas. If you are looking to expand, the system can scale up to eight speakers. 

STEP 4: Install the Subwoofer in the Ground or on a Hard Surface 

The subwoofer design supports installation on the ground, surface, deck, or buried in-ground to fit any outdoor landscape environment. The subwoofer has a 6-foot prewired cable. This can be plugged into any T connector. Positioning it near a wall will deliver deeper bass.

STEP 5: Connect the Amplifier & Audio Devices

The OHM system uses Bluetooth® V5.3, which provides superior range, a more stable connection, and faster, smarter switching between paired devices. There are multiple input options so you can connect to various devices. It also supports direct streaming from platforms like Spotify, Pandora, and Apple Music. Use any application of your preference!
