How To Wire Speakers With 4 Terminals: Setting It Up

Speakers make it possible for many people to enjoy music. Each speaker sold in the market comes with different features, but most of them are wired and connected in the same way. However, the cables can be quite overwhelming, especially if it involves multiple terminals. That's why many people want to know how to wire speakers with 4 or more terminals.

If you just recently bought a new speaker with multiple terminals, perhaps you want to check out this guide. Here, you will know how to connect or wire if a speaker has 4 terminals. This is to help you do the process correctly. 

Steps on How to Wire Speakers with 4 Terminals

Speakers commonly have two sets of terminals because it’s the usual set-up for bi-wiring. These approaches can potentially give your speakers a better sound and enhance the quality. However, if you see multiple terminals, it only means that the speaker is allowed to be “bi-amped.” 

If you bought speakers with 4 terminals, then here is how to wire speakers with 4 terminals or bi-amp it:

Step 1: Make sure that the entire system of your speaker is powered OFF. 
Step 2: Carefully remove the bi-wire bridges from the speaker. This is where the LPF & HPF crossovers and disconnect the crossover network's high and low frequency.
Step 3: Each amplifier channel should be connected to the respective speaker section. This will configure the receiver to the bi-amp setting. 
Step 4: Find the terminals at the back of the receiver that is intended for bi-amping. 
Step 5: Set the level of controls on the amplifier, so the signal given to your speaker will have the same level of volume. 
Step 6: If the amplifiers are identical, then it’s enough that you set the same all the amplifier’s level control. 
Step 7: Connect the receiver's front (main) speaker output to the left speaker's set of connections. 
Step 8: Do the same procedure on the other side. And that ends the wiring.

What is Bi-Amping? 

Knowing how to wire speakers with 4 terminals is the same as Bi-Amping. This approach separates the frequency signals by giving the high-frequency and low-frequency speakers to their amplification channels. Instead of 2 terminals, bi-amplifying comes with 4 terminals to provide greater control and yield better sound. That’s why many people proved that bi-amping is ideal for the home theater because it always makes a difference to the sound that your speaker produces. 

Once the speaker was bi-amped, it improved the sound's quality, especially during music and movie demands. You have to know that if the sound is being demanding, the power sent to each speaker can produce less constrained and better sound. Also, knowing how to wire speakers with 4 terminals always gives you the option of buying many amplifiers to power up the speakers.

As to the process of bi-amplifying, it's just the same as bi-wiring, but the only difference is that you have to power amp both sets of terminals. It has 4 sets of terminals, unlike the bi-wiring, which only has two sets of terminals in the speaker. By bi-amplifying, you always have to set terminals you wire into, thus producing better and quality sound.

Conclusion

Knowing how to wire speakers with 4 terminals is just an easy thing to do. Whether you decide to bi-wire or bi-amplify, it’s always important to know how the wiring works and know the right cable for the set-up. Since bi-amplifying aims to produce quality and better sounds, you need to do the procedures correctly and properly. With that, I hope the guidelines and procedures on how to wire speakers with 4 terminals helped you in doing it on your own.
