How to Wire Speakers

Speakers are devices used to transmit sound. You can often connect several speakers to one CD or DVD player. In home theater systems, a mixture of large and small speakers are used and placed strategically to provide users with optimum sound.

Speakers are wired together so they can all transmit the same sound. This will also allow the user to control them from one CD or DVD player. You can choose which parts of a room or house the speakers will be placed.

Determine the upper limit of the output of your amplifier and speakers. It is measured in ohms and written on the back of your amplifier and speakers. Make sure that your speakers’ output is not greater than the amplifier’s output. Turn off the amplifier and remove its plug.

There are three ways to wire speakers together.

1. The series mode requires the most speakers’ resistance. In this mode, the load is transversely divided among speakers depending on resistance. The power sent to each of the speakers is less than when using the other modes. The speakers with lower resistance will get more power. Make sure these can handle the electricity.

a. Attach the positive connection (red) of your amplifier into the positive input of one of the speakers.

b. Join the negative connection (not red) of one speaker with the other speaker’s positive connection.

c. Repeat until all of the speakers are joined.

d. Attach the negative connection on your last speaker to the negative on your amplifier.

2. The parallel mode will require the least speakers’ resistance. In this mode, the power sent to each speaker is equal. Only speakers with the same resistance can be used for this system.

a. Attach the positive connection of your amplifier to the positive connection of all the speakers.

b. Split cables will be needed to attach multiple speakers in this mode.

c. The connected wires will be attached to the negative connection of all of the speakers.

d. Attach one end of your cable into the amplifier’s negative jack.

3. A combination of series and parallel modes will allow you to attach more speakers with fewer ohms. This combination can maintain a constant load.

a. Attach the positive connection of the amplifier to the positive input of one of the speakers.

b. Connect the second speaker using a split cable.

c. Attach the two speakers using the series mode.

d. Hook up all of the speaker sets together.

e. Attach one end of your cable into the amplifier’s negative jack.
