This configuration allows for increased power handling and can be a good choice if you have an amplifier that is stable at such a low impedance.
To wire the subs in parallel for a 1.33 ohm load, you will need to connect the positive terminal of the first sub to the positive terminal of the second sub. Then, connect the positive terminal of the second sub to the positive terminal of the third sub. You will also need to connect the negative terminal of the first sub to the negative terminal of the second sub, and the negative terminal of the second sub to the negative terminal of the third sub.
This parallel wiring setup effectively combines the impedance of the subs. In this case, since each sub is 4 ohms, wiring them in parallel will reduce the overall impedance to approximately 1.33 ohms. This lower impedance can be beneficial for certain amplifier setups that are designed to handle lower loads.
It is important to note that when wiring in parallel, the power distribution among the subs may not be equal. The first sub in the wiring chain may receive slightly more power compared to the last sub. However, this difference is typically minimal and should not cause any significant issues.
Overall, wiring three DVC 4-ohm subs in parallel for a 1.33 ohm load can be a suitable option if you have an amplifier that can handle such a low impedance. This configuration allows for increased power handling and can provide a powerful and impactful audio experience.

If you want to wire three DVC (Dual Voice Coil) 4 ohm subwoofers in series, you can achieve a 12 ohm load. This configuration is different from wiring in parallel, as it combines the positive terminal of one subwoofer to the negative terminal of the next subwoofer, creating a continuous loop of connections.
To wire in series, start by connecting the positive terminal of your amplifier to the positive terminal of the first subwoofer. Then, take a wire and connect the negative terminal of the first subwoofer to the positive terminal of the second subwoofer. Repeat this process, connecting the negative terminal of the second subwoofer to the positive terminal of the third subwoofer.
This series wiring configuration adds up the impedance of each subwoofer, resulting in a 12 ohm load. This can be beneficial if your amplifier is better suited to driving higher impedance loads. However, keep in mind that the power output of your amplifier will be reduced when operating at a higher impedance.
- Connect the positive terminal of the amplifier to the positive terminal of the first subwoofer.
- Connect the negative terminal of the first subwoofer to the positive terminal of the second subwoofer.
- Connect the negative terminal of the second subwoofer to the positive terminal of the third subwoofer.
By wiring three DVC 4 ohm subwoofers in series, you can achieve a 12 ohm load, which may be suitable for certain amplifier setups. Make sure to match the impedance requirements of your amplifier and subwoofers to avoid any potential issues.
Option 3: Wiring in a Combination of Series and Parallel for a 4 Ohm Load
When wiring three DVC (Dual Voice Coil) 4 ohm subwoofers, there are various wiring configurations that can be used to achieve a 4 ohm load. One option is to use a combination of series and parallel wiring, which can provide the desired impedance. This method involves both series and parallel connections to create a balanced load for the amplifier.
To wire the subs in this configuration, you would first need to identify which terminals on each subwoofer are positive and negative. Each subwoofer will have two sets of terminals, one for each voice coil. Once you have identified the terminals, you can begin the wiring process.
- Start by wiring the two voice coils of each subwoofer in series. This means connecting the positive terminal of one voice coil to the negative terminal of the other voice coil on each subwoofer. This will create a 8 ohm load for each subwoofer.
- Next, wire the three subwoofers in parallel. This involves connecting the positive terminal of the first subwoofer to the positive terminal of the second subwoofer, and then connecting the positive terminals of the second and third subwoofers together. Repeat the same process for the negative terminals of the subwoofers. This parallel connection will result in a 2.67 ohm load.
- Finally, connect the positive and negative terminals of the parallel connection to the corresponding terminals on the amplifier. This will give you a combined 4 ohm load for the three DVC 4 ohm subwoofers.
It’s important to note that when wiring subwoofers in a combination of series and parallel, you should double-check all connections to ensure they are secure and properly insulated. This will prevent any potential damage to the subwoofers or amplifier.
