How to Install Subwoofer in Golf Cart? (Tips for Golf Carts Audio)

Golf carts are like any vehicle, and they can benefit from a performance boost. Adding a subwoofer to your golf cart is an easy and rewarding way of enhancing its step power and volume range.

Whether you’re looking for pounding bass or just improved audio clarity, adding a subwoofer is the perfect way to upgrade your ride with minimal effort.

To install a subwoofer in a golf cart, follow these steps:

#1. Choose a subwoofer and amplifier that fit your golf cart’s power needs.

#2. Add a 12V battery to power the subwoofer and amplifier.

#3. Mount the amplifier and subwoofer either under a seat or in a storage compartment.

#4. Connect power and ground wires from the battery to the amplifier, and then use a speaker wire between the amplifier and subwoofer.

#5. Test the system and tune your amp to ensure it is working correctly.

Tip: If you prefer straightforward installation without extra wiring, I recommend checking the 8″ ECOXGEAR S08 active subwoofer with a built-in 500W amplifier.

In this guide, I will walk you through everything you need to know about installing a sub in your golf car and what equipment to use.

Do I Need a Subwoofer in My Golf Cart?

Adding a subwoofer to the cart can significantly enhance the overall audio quality of your music, making your ride more enjoyable.

Although you can use simpler to install popular soundbars like ECOXGEAR Soundextreme SE26 (link to Amazon), having a subwoofer with an 8″, 10″, or larger driver puts the bass and the whole dynamics of your audio system to another level.

When it comes to choosing a sub and the amplifier for your golf cart, there are several factors to consider, including size, power, and durability. 

Additionally, the installation process can be complex, so it’s important to take your time and follow the instructions carefully to ensure a successful outcome.

Choosing the Right Subwoofer

When it comes to choosing a subwoofer for your golf cart, there are several types to consider.

Shallow-mount subwoofers are designed to fit in tight spaces and can be a good choice for golf carts but also for cars with limited space. Marine subwoofers are designed to withstand harsh outdoor elements and are typically waterproof and dustproof.

Weather-resistant subwoofers are also a good choice for outdoor use and are designed to withstand extreme temperatures and humidity.

For me, the best solution is to install an active waterproof sub with high sensitivity. These can be loud and do not require high-quality amps since you will use them outdoors.

Choosing the Right Amplifier

If you decide to install a passive subwoofer, you need an amplifier, and it does not matter what kind of subwoofer it is. The radio will not be able to give it enough power in watts.

When choosing an amplifier for your cart subwoofer, a compact, low-wattage amplifier is typically the best choice. It’s also possible to use a separate battery for the subwoofer, but this can be more complex to set up.

Placing the Subwoofer on the Golf Cart

When placing the subwoofer on your golf cart, choose a location that will provide optimal audio quality.

Installing a sub in the rear compartment or under a seat is typically a good choice, as it can help to enhance the bass and deliver a more immersive audio experience, but if you have a sizeable enclosure, the better position may be right behind the seat.

Connecting the Subwoofer to the Radio

Once you have chosen a suitable sub and amplifier, it’s time to start the installation process.

To get started, you will need a few items, such as RCA cables, wire strippers, and electrical tape.

If you install a 12V amplifier, do not forget about a voltage converter (link to Amazon) from either 36 or 48V to 12V required by the car amplifier.

#1. Begin by finding the RCA output on the back of your golf cart’s radio. It is usually located near the wiring harness or antenna port.

Connect the RCA cables to the output, making sure to match the colors of the wires to the corresponding inputs on the amplifier.

#2. Next, run the RCA cables from the radio to the amplifier.

Again, a good practice is to keep the wires away from any power cables or other sources of interference to prevent noise or distortion in the sound.

You may need to drill a small hole in the golf cart’s body to run the cables.

#3. Once the RCA cables are connected to the amplifier, you will need to strip the ends of the speaker wire that you ran to the subwoofer.

Use wire strippers to remove a small section of insulation from the ends of the wire and secure them in the terminals.

#4. Connect the speaker wire to the appropriate terminals on the amplifier, making sure to match the positive and negative terminals to the corresponding wires.

Use electrical tape or wire connectors to secure the connections and prevent any interference or short circuits.

#5. Finally, adjust the settings on your amplifier and radio to optimize quality of the audio output.

In most cases, it means adjusting the gain, crossover, and bass boost to get the best sound for your subwoofer.

It’s important to note that the audio quality will depend on the type and quality of the subwoofer, amplifier, and radio you have chosen.

Be sure to do your research and choose equipment that is specifically designed for use in golf carts and other outdoor environments.

Connecting the 12V Battery to the Golf Cart’s Electrical System

If you want to add a 12V battery to a 48V installation in the cart, you will need to use a voltage converter or voltage reducer.

The voltage reducer or converter is a device that is designed to step down the voltage from the golf cart’s 48V system to 12V, which can be used to power accessories or other devices that require 12V power.

Here are the general steps to install a voltage reducer or converter:

#1. Identify a suitable location to install the voltage reducer or converter. 

A good place could be inside the golf cart’s battery compartment, under the seat, or in a location that’s easily accessible, but I recommend it as close as possible to the battery.

#2. Disconnect the negative cable of the 48V battery to avoid any electrical shock or shorts.

#3. Mount the voltage converter using screws or zip ties, ensuring it’s securely fastened.

#4. Connect the 48V input wires to the voltage reducer or converter. These wires should be connected to the positive and negative terminals of the reducer.

#5. Connect the 12V output wires to the voltage reducer or converter. These wires should be connected to the positive and negative terminals of the converter.

#6. Reconnect the negative cable of the 48V battery.

#7. Test the system to ensure the voltage converter is working properly.

It’s important to note that adding a 12V battery to a golf cart’s 48V system may impact the overall battery life and performance, so I recommend talking to the professional before making any modifications to your golf cart’s electrical system.


In conclusion, connecting the subwoofer to the radio is a crucial step in the installation process. With the right tools and a little patience, you can enjoy high-quality, powerful sound while cruising the greens.

Just be sure to take your time, follow the instructions carefully, and enjoy the ride.
