How to Run a 4-Ohm Speaker Load on a Deluxe Blues Reissue

Running a 4-ohm speaker load on a deluxe blues reissue is a simple thing to do since most audio systems have the option enabled in them. In this case, the 4-ohm speaker running with the blues deluxe reissue is like wiring two channels to one speaker. The process is simple, but it can cause some problems with your amplifier that you need to be careful with the setup.

You can use various methods to run the 4-ohm speaker load on a blue deluxe reissue, including bridging the amplifier, using a mono switch, and a dual voice coil speaker. Avoid using a parallel method of connection with these methods.

The article below will provide a full description of the methods and how to connect them, and then the other thing will follow, like the conclusion

1. Wiring left and right channels together

Wiring left and right channels together

To connect a 4-ohm speaker load to a blue deluxe reissue, consider wiring the left and right channels together even though the method is not recommended for use. In this method, the right channel is directly connected to the left channel to create a single output connection to connect to the main speaker.

The method is not recommended because the wiring creates a parallel type of connection that can cause damage to the amplifier when the user is not keen on it. The parallel connection also causes the sound quality to be poor since the two connected channels have low impedance and can short each other in the connection. Check the steps below for the connection to occur.

i. Connect one wire on the positive terminal to one of the blue deluxe reissues and the other on the second channel. After connecting the two wires, put the ends together to connect them to the 4-ohm speaker load. Repeat the same procedure with the negative terminals of the channels.

ii. After wiring all the two channels and connecting them to the speaker, take the positive wires from the speaker and the negative wire from the speaker and join them together.

2. Bridging the amplifier

Bridging the amplifier

Bridging the amplifier is another method you can use when connecting a 4-ohm speaker load to a blue deluxe reissue. Bridging an amplifier combines two channels, with the resistance becoming half the normal ohms. When the resistance is lower, the speaker will consume a lot of current to run. The methods help to send a single signal to the speaker.

With the bridging process, you need to check the amplifier with its user manual and specifications. There are a few things to consider when using this method:

  • When bridging the amplifier, the resistance is half the normal resistance.
  • Amplifiers are different, so you need to check if your amplifier is good for bridging.
  • Check on the amplifiers manual on the diagrams showing the terminals to the bridge.
  • Some amplifiers are good for both right and left

Steps of bridging an amplifier

i. Identify the channel terminals by checking the amplifier to locate them.

ii. Pick the wires from the speaker and fix them to the channels where you will connect the negative to negative and the positive to the positive terminal on the speaker.

iii. Repeat the same process, even if you are bridging several channel amplifiers in the same way. The method is good since it allows the speaker to get power from two channels and still produces good quality sound.

3. Use a mono switch

The process works by converting two channel amplifiers to one amplifier. The method is similar to the bridging method since it combines the left and right signal with one speaker amplifier and the speaker. The method can be permanent since all operations are done on the internal parts of the speaker amplifier. It can also remove some effects on your speaker, like the stereophonic effect, and cause the signal to be smooth.

4. Use the double voice coil speaker

Use the double voice coil speaker

When using this type of speaker, you need to have isolated coils since the normal dual voice coil speaker has two voice coils that enable the single speaker to cause the output to stereo channels through one speaker. You can say that you get a stereo signal from a single speaker. Connecting speakers using this method is confusing, such that you need to know how to connect the wires within the coil properly. There are different ways of connecting a dual voice coil speaker, which includes the following:

i. Use a speaker wire to connect both the positive terminals of the speaker together.

ii. Use another speaker wire to connect the negative terminals like the first step.

iii. Connect the negative lead of the amplifier to the negative side of the speaker. Repeat the process with the positive side too.

Frequently asked questions:

  • Why is it important to connect two channels to one speaker?

Wiring two channels to one speaker is another way of increasing the speaker’s power output, and it also helps you understand what the speaker needs and what is good for the amplifier.

  • Is it good to wire a single speaker to two sources?

Yes, it is good to wire one speaker to two sources so long as you consider using a switch, speaker switches that are either manual or automatic.

In the guide above, there are a few methods among several methods that you can employ when running a 4-ohm speaker load on a blue deluxe reissue. Before trying to connect the two, consider identifying the specifications of a blue deluxe reissue for a successful connection. Remember to avoid any connection that uses the parallel method since it is not advisable.

Consider using the modern amplifiers and speakers since the older versions lack some features for the connection. Check on using the bridging method and mono switch since they are among the best methods to use.
