4 Dual 2 Ohm Subwoofer Wiring Diagram

Subwoofers are essential components of any car audio system. They are responsible for producing the low-frequency sound that gives music its depth and power. Most high-quality subwoofers are made with dual voice coils, which offer more flexibility when it comes to wiring. In this article, we will explore the wiring diagram for 4 dual 2 ohm subwoofers.

What Are Dual Voice Coil Subwoofers?

Dual voice coil subwoofers, also known as DVC subwoofers, have two separate voice coils mounted on the same cylinder. Each coil has its own positive and negative terminals, which allows for greater flexibility when it comes to wiring. DVC subwoofers are available in 2-ohm, 4-ohm, and 8-ohm configurations and offer a variety of wiring options.

What Is the Advantage of Using Dual Voice Coil Subwoofers?

The main advantage of using dual voice coil subwoofers is flexibility. With two separate voice coils, you can wire your subwoofers in a variety of configurations to achieve the desired impedance. Dual voice coil subwoofers also allow for greater power handling, as each voice coil can handle a portion of the overall power.

What Is the Difference Between 2-Ohm and 4-Ohm Dual Voice Coil Subwoofers?

The difference between 2-ohm and 4-ohm dual voice coil subwoofers is in their wiring options. A 2-ohm DVC subwoofer can be wired to have a total impedance of 1 ohm, 2 ohms or 4 ohms, while a 4-ohm DVC subwoofer can be wired to have a total impedance of 2 ohms or 8 ohms.

What Is Impedance?

Impedance is the measure of the opposition of an electrical circuit to the flow of current. In car audio systems, the impedance of speakers and subwoofers is measured in ohms. The impedance of a subwoofer affects the amount of power that the amplifier can provide, and the overall sound quality of the system.

What Is the Optimal Impedance for a Car Audio System?

The optimal impedance for a car audio system depends on the amplifier and the total number of subwoofers. In general, a system with a single subwoofer should have an impedance of 4 ohms, while a system with multiple subwoofers should have an impedance of 2 or 1 ohm.

Wiring Diagram for 4 Dual 2 Ohm Subwoofers

The wiring diagram for 4 dual 2 ohm subwoofers allows for a variety of wiring options to achieve the desired impedance. In this diagram, we will be wiring the subwoofers in parallel to achieve a total impedance of 1 ohm.

Subwoofer 1 Subwoofer 2 Subwoofer 3 Subwoofer 4

Positive Terminal 1

Positive Terminal 2

Positive Terminal 3

Positive Terminal 4

Negative Terminal 1

Negative Terminal 2

Negative Terminal 3

Negative Terminal 4

To wire the subwoofers in parallel, connect the positive terminals of all four subwoofers together, and connect the negative terminals of all four subwoofers together. This will result in a total impedance of 1 ohm.

How to Calculate the Total Impedance of the Wiring Diagram

To calculate the total impedance of the wiring diagram for 4 dual 2 ohm subwoofers, you need to use the following formula:

Total Impedance = (Subwoofer Impedance) / (Number of Subwoofers Connected in Parallel)

For this wiring diagram, we have four subwoofers with an impedance of 2 ohms each. When wired in parallel, the total impedance will be:

Total Impedance = 2 ohms / 4 = 0.5 ohms

FAQ

What Happens If I Wire My Subwoofers in Series Instead of Parallel?

If you wire your subwoofers in series instead of parallel, the total impedance of the system will increase. For example, if you wired the same four subwoofers in series, the total impedance would be 8 ohms. This would result in less power being delivered to the subwoofers and a weaker overall sound.

Can I Wire My Subwoofers to Have a Total Impedance of 2 Ohms?

Yes, you can wire your subwoofers to have a total impedance of 2 ohms. To achieve this, you would need to wire each pair of subwoofers in series, and then wire the two pairs together in parallel. This would result in a total impedance of 2 ohms.

What Is the Maximum Power That My Amplifier Can Deliver?

The maximum power that your amplifier can deliver depends on the RMS power rating of the amplifier and the impedance of the subwoofers. To determine the maximum power, use the following formula:

Maximum Power = (RMS Power) x (Impedance)

For example, if you have an amplifier with an RMS power rating of 1000 watts and you are using 4 dual 2 ohm subwoofers wired in parallel to achieve a total impedance of 1 ohm, the maximum power that the amplifier can deliver is:

Maximum Power = 1000 watts x 1 ohm = 1000 watts

What Is the Best Way to Mount My Subwoofers?

The best way to mount your subwoofers depends on your car and your personal preferences. Some popular mounting options include mounting the subwoofers in an enclosure in the trunk, mounting them in a custom box in the backseat, or mounting them in the doors or kick panels. It is important to make sure that the subwoofers are securely mounted to prevent damage to them or the car.
