Are you looking to upgrade your car’s audio system with a subwoofer? One of the most important aspects of installing a subwoofer is wiring it correctly. If you have a dual 4 ohm subwoofer, you may be wondering how to wire it for optimal performance. In this article, we will guide you through the process of wiring a dual 4 ohm subwoofer to help you get the most out of your car audio system.
Wiring a dual 4 ohm subwoofer can be a bit tricky, but with the right information and tools, it can be done easily. The first step is to determine the impedance load you want to achieve. You can wire the subwoofer in series or parallel to achieve different impedance loads. Series wiring will increase the impedance load, while parallel wiring will decrease it. Once you have determined the impedance load you want to achieve, you can start wiring your subwoofer.
Understanding the Basics
If you’re new to car audio, wiring a dual 4 ohm subwoofer can seem intimidating. But don’t worry, it’s actually quite simple once you understand the basics.
First, let’s talk about impedance. Impedance is the electrical resistance of a circuit, measured in ohms. When wiring subwoofers, you need to match the impedance of the subwoofer to the impedance of the amplifier. If the impedance is too high, you won’t get enough power to the subwoofer. If the impedance is too low, you could damage the amplifier.
Dual 4 ohm subwoofers are a popular choice for car audio enthusiasts because they offer more wiring options than single voice coil subwoofers. With a dual 4 ohm subwoofer, you can wire it in parallel to get a 2 ohm load, or in series to get an 8 ohm load.
To wire a dual 4 ohm subwoofer, you’ll need to connect the positive (+) terminal of one voice coil to the negative (-) terminal of the other voice coil. Then, connect the remaining positive (+) and negative (-) terminals to your amplifier.
It’s important to note that when wiring subwoofers, you need to pay attention to the ohm rating of your amplifier. If your amplifier is only stable at 2 ohms, you’ll need to wire your subwoofer in parallel to get a 2 ohm load. If your amplifier is only stable at 4 ohms, you’ll need to wire your subwoofer in series to get an 8 ohm load.
When it comes to choosing an amplifier for your dual 4 ohm subwoofer, you’ll want to look at the wattage rating. Make sure your amplifier can handle the wattage of your subwoofer. For example, if your subwoofer is rated at 500 watts RMS, you’ll want to choose an amplifier that can deliver at least 500 watts RMS at the impedance you’re wiring your subwoofer to.
wiring a dual 4 ohm subwoofer is a simple process once you understand the basics. Just make sure to pay attention to the ohm rating of your amplifier and match it to the impedance of your subwoofer. And don’t forget to choose an amplifier that can handle the wattage of your subwoofer.
Identifying Subwoofer Types
When it comes to wiring a subwoofer, the first step is to identify its type. There are two main types of subwoofers: single voice coil (SVC) and dual voice coil (DVC).
A single voice coil subwoofer has only one voice coil and one set of terminals. It can be wired in parallel or series, depending on the desired impedance load. On the other hand, a dual voice coil subwoofer has two voice coils and two sets of terminals. This gives you more wiring options and allows for greater flexibility in your setup.
When identifying a DVC subwoofer, it’s important to note the impedance of each coil. Dual voice coils can be wired in series or parallel, which affects the overall impedance load. For example, wiring two 4-ohm DVC subs in parallel would result in a 1-ohm load, while wiring them in series would result in an 8-ohm load.
It’s also important to note the number of voice coils in your subwoofer setup. If you have multiple subwoofers, you may need to wire them in series or parallel to achieve the desired impedance load. For example, wiring two 4-ohm DVC subs in series would result in an 8-ohm load, while wiring them in parallel would result in a 2-ohm load.
understanding the type and configuration of your subwoofer is crucial when wiring your system. Be sure to consult your subwoofer’s manual or manufacturer’s website for specific wiring diagrams and instructions.

Wiring Configurations
When wiring dual 4 ohm subwoofers, there are a few wiring configurations to consider. The most common wiring options are series and parallel wiring, and series-parallel wiring. Each wiring configuration has its own benefits and drawbacks, so it’s important to choose the one that best suits your needs.
Series Wiring
In series wiring, you connect the positive terminal of one subwoofer to the negative terminal of the other subwoofer. Then, you connect the remaining positive and negative terminals to your amplifier. This wiring configuration results in an 8 ohm load, which can be useful if you have an amplifier that can’t handle a lower impedance. However, it also reduces the overall power output of your system.
Parallel Wiring
In parallel wiring, you connect the positive terminals of both subwoofers together and the negative terminals together. Then, you connect the remaining positive and negative terminals to your amplifier. This wiring configuration results in a 2 ohm load, which can increase the power output of your system. However, it can also put more strain on your amplifier and cause it to overheat.
Series-Parallel Wiring
Series-parallel wiring combines the benefits of both series and parallel wiring. In this configuration, you wire each subwoofer in series, and then connect the two sets of subwoofers in parallel. This wiring configuration results in a 4 ohm load, which is a good compromise between power output and amplifier strain.
When choosing a wiring configuration, it’s important to consult a wiring diagram to ensure that you are wiring your subwoofers correctly. There are many subwoofer wiring diagrams available online, and these can be a useful resource when deciding on a wiring configuration.
Understanding Terminals
When it comes to wiring a dual 4 ohm subwoofer, understanding the different terminals is crucial. These terminals are where you will connect the wires that run from your amplifier to your subwoofer, allowing for the transfer of electrical signals that produce sound.
There are typically two sets of terminals on a dual 4 ohm subwoofer: one positive and one negative set for each voice coil. It’s important to note that the positive and negative terminals for each voice coil are not connected to each other. This means that you will need to wire each voice coil separately to your amplifier.
The positive terminals are typically marked with a “+” symbol, while the negative terminals are marked with a “-” symbol. It’s important to connect the positive wire from your amplifier to the positive terminal on your subwoofer, and the negative wire from your amplifier to the negative terminal on your subwoofer. Connecting the wires incorrectly can result in poor sound quality or even damage to your equipment.
It’s also important to ensure that the wires are securely fastened to the terminals. Loose connections can result in a loss of signal or even damage to your equipment. You can use a screwdriver to tighten the connections if necessary.
understanding the different terminals on your dual 4 ohm subwoofer is crucial when wiring it to your amplifier. Make sure to connect the positive and negative wires correctly, and ensure that the connections are secure to avoid any issues with sound quality or equipment damage.
Impedance and Load
When wiring dual 4 ohm subwoofers, it’s important to understand impedance and load. Impedance is the electrical resistance that the subwoofer presents to the amplifier’s output signal, while load refers to the total amount of impedance seen by the amplifier.
Dual voice coil (DVC) subwoofers have two separate voice coils, each with its own positive and negative terminal. This allows for more wiring options and flexibility in matching the subwoofer to the amplifier. Each voice coil has its own impedance rating, usually 2, 4, or 8 ohms.
When wiring dual 4 ohm subwoofers, there are two common options: series and parallel wiring. Series wiring involves connecting the positive terminal of one voice coil to the negative terminal of the other, and then connecting the remaining positive and negative terminals to the amplifier. This results in an impedance load that is the sum of the two voice coils, or 8 ohms in the case of dual 4 ohm subwoofers.
Parallel wiring involves connecting the positive terminals together and the negative terminals together, and then connecting the resulting combined positive and negative terminals to the amplifier. This results in an impedance load that is half of the individual voice coil impedance, or 2 ohms in the case of dual 4 ohm subwoofers.
It’s important to note that when wiring multiple subwoofers, the total impedance load seen by the amplifier will depend on both the individual subwoofer impedances and the wiring configuration. For example, wiring two dual 4 ohm subwoofers in parallel will result in a total impedance load of 1 ohm, which is generally not recommended for most amplifiers. It’s important to check the amplifier’s specifications and wiring diagrams to ensure that the subwoofers are wired correctly and safely.
Power and Performance
Wiring your dual 4 ohm subwoofer correctly can make a significant difference in your car audio system’s sound quality and performance. The power handling rating of your subwoofer determines the amount of power it can handle without getting damaged. If you exceed the power handling rating, you risk blowing the subwoofer.
When choosing an amplifier to power your subwoofer, you need to ensure that the RMS wattage of the amplifier matches the RMS wattage of the subwoofer. If the amplifier’s RMS wattage is too low, you won’t get the full potential of the subwoofer. On the other hand, if the amplifier’s RMS wattage is too high, you risk damaging the subwoofer.
To get the best performance out of your subwoofer, you need to ensure that it is wired correctly. Wiring your subwoofer in parallel will result in a 2 ohm load, which will give you more power. Wiring your subwoofer in series will result in an 8 ohm load, which will give you less power.
When wiring your subwoofer, ensure that you use the correct gauge wire. Using a wire that is too thin can result in a voltage drop, which can affect the subwoofer’s performance. Using a wire that is too thick can be a waste of money and space.
wiring your dual 4 ohm subwoofer correctly is crucial to getting the best sound quality and performance out of your car audio system. Ensure that you choose an amplifier with the correct RMS wattage, use the correct gauge wire, and wire your subwoofer correctly to get the most out of your subwoofer.
