Brief Overview of Car Audio Systems
Today’s setups often include multiple speakers, powerful amplifiers, and high-quality head units that deliver crystal clear sounds with high “watts RMS” (root mean square), a measure of continuous power handling.
All these components combined, form the car audio system. Now, consider this: Where does all this power come from?
The answer is your car’s alternator and battery. The alternator charges the battery while the engine is running, supplying power to the car’s electrical systems, including your car audio setup.
However, the stock alternator and battery in most cars are designed to handle the standard electrical load, not the extra power demands of an advanced car audio system.
So what happens when the power demand of your car audio system exceeds what your stock or even high-output alternator can provide? You might experience dimming lights, a strained alternator, or worse, a drained battery.
This is where the concept of dual alternators comes in.
What Is a Dual Alternator Bracket?
A dual alternator bracket is a mounting accessory that allows you to install two alternators in your car. Yes, you heard it right, two alternators!
By using a dual alternator bracket in car audio setups, you can add an extra alternator to your vehicle’s engine bay. This extra alternator helps meet the additional power demands of your advanced car audio system without stressing the battery or the existing alternator.
The function of this bracket is quite straightforward yet crucial. It holds the added alternator securely in place, ensuring it aligns properly with the engine’s belt drive system.
Remember, alternators function by converting mechanical energy (from the engine via the drive belt) into electrical energy.
The role of the dual alternator bracket kit becomes even more significant when it comes to car audio. If you have an advanced audio setup with multiple amplifiers that pump out high watts RMS, a dual alternator setup can be a game changer.
It ensures you have a stable, high current power supply for your audio system, without draining your battery or straining your original alternator.
So, if you’re serious about your car audio, and I can tell you are, considering a dual alternator bracket might be a step in the right direction.
Not only does it solve power problems, but it also ensures you get the best performance out of your car stereo setup. After all, no one likes a great track interrupted by power issues, right?
Understanding the Workings of a Dual Alternator Bracket
Alright, let’s dig a bit deeper into the concept of a dual alternator bracket to understand the specifics.
How a Dual Alternator Bracket Works
The beauty of a dual alternator bracket lies in its simplicity. A car’s standard setup includes a single alternator.
When the engine is running, the serpentine belt (or drive belt) spins the alternator, which generates electricity. This electricity is used to power the various electrical systems in the car and charge the battery.
However, when you install a dual alternator bracket, you’re essentially setting up another alternator in your car. Now, I’ve heard many people ask: “Does this mean the power generation is doubled?” Well, not exactly, but it certainly increases your car’s power generation capacity.
When you’re using a dual alternator bracket in car audio setups, the bracket itself doesn’t generate power. Instead, it provides a secure mount for the second alternator.
Once installed, both alternators are driven by the engine via the serpentine belt, generating and distributing electrical power independently.
The benefit? You can dedicate the additional alternator to your car stereo setup, leaving the primary alternator to take care of the rest of the vehicle’s electrical needs.
This separation of power sources reduces the strain on your battery and ensures a more stable power supply for your car audio system.
Installation of Dual Alternator Bracket
Let’s move on to the next stage: installing the dual alternator bracket. I know, it might seem like a daunting task, especially if you’re not usually one for getting your hands dirty under the hood.
But trust me, it’s not as tough as it might appear once you have the right tools and follow the correct procedure.
How to Install a Dual Alternator Bracket
First things first, we need to gather all the necessary tools for the installation process.
These include a socket set, wrenches, screwdrivers, and safety equipment such as gloves and protective glasses. It’s always better to be safe than sorry, right?
Here’s a simplified step-by-step guide on how to install a dual alternator bracket:
#1. Disconnect the battery: Always the first step when you’re dealing with the electrical system of your car. This prevents any accidental shorts or shocks during the installation process.
#2: Remove the alternator:
- Loosen the tension on the serpentine belt or V-belt by using a wrench or socket to rotate the tensioner pulley. Slide the belt off the alternator pulley.
- Remove the mounting bolts that secure the alternator to the engine block using a socket or wrench. You may need to access these bolts from underneath the car or through the wheel well.
- Once the bolts are removed, carefully lift the alternator out of its mounting brackets and remove it from the engine compartment.
#3. Identify the mounting points: Depending on your vehicle’s make and model, the dual alternator bracket will have specific mounting points. Refer to the installation instructions for exact details.

#6. Wire the alternators: Connect both alternators to your car’s electrical system. This involves connecting the output of the alternator to the battery and grounding the alternator to the vehicle’s chassis.
Once the installation is complete, double-check all connections, reconnect the battery, and start the vehicle to ensure everything is working correctly.
Using a Dual Alternator Kit
You might be wondering, “Isn’t there an easier way to do all of this?” Well, you’re in luck because there’s something known as a dual alternator kit.
A dual alternator kit is a comprehensive package that includes everything you need to set up a dual alternator system in your car. This usually includes a custom-made dual alternator bracket, a secondary alternator, and sometimes even the necessary wiring and hardware.
Using a dual alternator kit simplifies the installation process as everything is designed to work together.
The bracket is designed to fit your specific vehicle model, and the additional alternator is matched to work effectively with your existing alternator.
Not to mention, these kits come with detailed installation instructions tailored to your car model.
The benefits of using a dual alternator kit are quite clear: It saves you time in finding compatible parts, and it eases the installation process with comprehensive instructions and matched components.
How to Connect Two Alternators in Parallel
Now, installing a dual bracket is one thing, but connecting alternators so the whole system works is another.
A parallel connection means that the voltage output remains the same, but the capacity (or amperage) is increased.
Here’s how you can connect two alternators in parallel:
#1. Install the second alternator using the dual alternator bracket kit.
#2. Connect the positive terminals of both alternators and then to the battery’s positive terminal.
#3. Connect the ground terminals of both alternators and then to the vehicle’s chassis.
#4. Ensure that the voltage regulators of both alternators are connected and working together.
The parallel setup ensures that the load (in this case, your high-demand car audio system) is shared between the two alternators. This effectively increases the power available to your car audio system without overtaxing a single alternator.
Compatibility and Safety of Dual Alternator Brackets
Alright, I can tell what you’re thinking. “Can I really use a dual alternator bracket in my car?” and “Is it even safe to do so?”
