How To Connect 2 Subwoofers To One Amp? Pro Guide

You may consider connecting two subwoofers to one amplifier if you want to add some extra low-end oomph to your sound system. This can be a great way to get even more bass response from your system, but there are a few things you need to know before you start hooking everything up. Here, we’ll show you how to connect 2 subwoofers to one amp safely and properly and give you some tips on getting the most out of your dual-sub setup. Let’s get started!

Ways to Connect 2 Subwoofers to One Amp:

There are six ways to connect two subwoofers to one amplifier. The first three methods are the most common, while the last three methods are less common but can provide better performance in some cases.

In-Series Connection:

In a series connection, the positive terminal of one subwoofer is connected to the negative terminal of the other subwoofer, and both subs share the same amplifier. This connection’s total impedance (resistance) is equal to the sum of the individual impedances of each sub. This method is easy to set up and can be used with any type of amplifier, but it will decrease power output for both subs.

In-Parallel Connection:

In a parallel connection, the positive terminal of one subwoofer is connected to the positive terminal of the other subwoofer, and the negative terminals are connected together. This connection’s total impedance is equal to the individual impedances of each subdivided by two. This method is easy to set up and can be used with any type of amplifier, but it will decrease power output for both subs.

Dual Voice Coil Connection:

A dual voice coil subwoofer has two positive and two negative terminals. This allows for two different wiring configurations: in-series or in parallel. In a series connection, the two positive terminals are connected. This connection’s total impedance is equal to the sum of the individual impedances of each sub. The two positive terminals are connected in a parallel connection, and the two negative terminals are connected. This connection’s total impedance is equal to the individual impedances of each divided by two.

Bi-Wiring Connection:

Bi-wiring involves connecting the positive terminal of one subwoofer to the positive terminal of the other subwoofer and connecting the negative terminal of one subwoofer to the negative terminal of the other subwoofer. This effectively creates two parallel circuits, each with its own amplifier. The power output will be greater than a single amplifier, but the total impedance will be lower than a single amplifier.

Active Crossover Connection:

An active crossover is a device that splits the signal into high and low frequencies before it reaches the amplifier. The high-frequency signal is sent to one subwoofer, and the low-frequency signal is sent to the other subwoofer.

Passive Crossover Connection:

A passive crossover is a device that splits the signal into high and low frequencies after it reaches the amplifier. The high-frequency signal is sent to one subwoofer, and the low-frequency signal is sent to the other subwoofer.

Why Is It Important to Connect 2 Subwoofers to One Amp?

There are six reasons why you might want to connect 2 subwoofers to one amplifier.

More power:

A stereo amplifier can put out more power when connected to two subwoofers than when connected to one subwoofer. This is because the amplifier shares the load between the two subs instead of having all the load applied to just one sub.

More control:

A stereo amplifier can provide more control over two subs than over one sub. This is because it can send more equalized power to each sub and better match their response characteristics.

The Increased Output Below 40 Hz:

When a single subwoofer is used, its output below 40 Hz is usually not very loud because most of its output energy is above that frequency range. But by using two subs, their outputs below 40 Hz can be added together to produce a louder, fuller bass response.

Greater Headroom:

When two subs are connected to an amplifier, they can each handle half of the power output from the amp. This means that each sub has more “headroom” to handle transients and other peaks in the music without distortion.

Better Mixing and Matching:

They may not sound the same if you have two subs of different brands or models. But by connecting them to the same amplifier, you can “mix and match” them to get a better overall bass response.

More Flexibility in Placement:

If you have two subs, you can place them in different locations in the room to get the best bass response. This is because each subwoofer’s output can be directed to a different location.

How to Choose an Amp to Connect 2 Subwoofers?

There are a few things to consider when choosing an amp to connect 2 subwoofers.

  • The most important factor is the wattage of the amp. You’ll need an amp that can provide enough power to drive both subs.
  • You’ll also want to make sure that the amp has a low-pass filter so that you can set the cutoff frequency for the subs. This will help ensure that they play together seamlessly and don’t produce any unwanted harmonics.
  • Finally, you’ll need to ensure that the amp is compatible with your speaker wiring configuration. Most amps have either a 2- or 4-channel input, so you’ll need to ensure your subs are wired in parallel or series accordingly.

Conclusion:

In conclusion, connecting two subwoofers to one amp is a great way to get more bass. Everything you need to know about connecting two subwoofers to one amplifier. By following the simple steps outlined in this article, you can easily create a powerful and immersive home audio experience for yourself. Just be sure to experiment with placement and settings until you find what works best for your listening environment. And most importantly, have fun!
