An 8-ohm speaker comes with wire color codes that one needs to know before connecting them. Some of the color codes include; red, blue, and black. In the 8-ohm speaker, the red wire is the +ve conductor; blue is a –ve wire and black is also a –ve conductor.
Understanding the colors make it easier for you to connect your speaker successfully. Connecting the wires allows you to get the best sound system functioning correctly. Also, it is essential to test the polarity of the cables using the multimeter to get wires that are working correctly.
Fortunately, the article below shows the steps to follow to wire speaker 8-ohm blue, black and red to red and black. Please read the article below to gather more additional information that is of great help. Let’s start.
Steps on how to wire speaker 8-ohm blue, black and red to be red and black
The wires work to transmit electrical signals from the receiver to the speaker, such as the 8ohm speaker. The cables come in different colors, such as; red, blue, and black. The colors are either negative or positive.

- 8ohm speaker.
- Wires that are red, blue and black.
- Receiver or amplifier.
The positive wire is usually red, whereas the ground or negative is black. On the other hand, colors are not possible with 8ohm speaker wires. The good news is that when it comes to speakers, it doesn’t matter which one you choose as your positive and which one you choose as your negative as long as you’re consistent. The wire that connects to the red terminal on your amplifier should eventually connect to the red terminal on your 8ohm speaker. Follow the steps below;
I. Check the condition of the wires to see if they are functioning correctly.
II. Look for the wire in the pair with the lettering or other marks that are on it (a line, for example) to prevent the occurrence of reverse polarization.
III. Choose that wire as the negative wire and cap both ends with black caps.
IV. Cap the other wire with red caps.
V. Then plug it in, and the two red terminals will join. You can use a crimping tool.
VI. Join the blue terminal of the receiver to the black terminal of the speaker and avoid connecting a negative terminal to a positive one as it may harm the device.
Even if that fails and you accidentally cross them, you’re unlikely to notice the difference in the worst-case situation. It has to do with the “phase” of the 8ohm speakers; it doesn’t harm them, but it can occasionally muck up the 8ohm sound experience and make it difficult to find a “sweet place” to listen from.

What is the best way to tell if a speaker wire is positive or negative?
i. Here’s a rundown of the most frequent ways to figure it out:
ii. There is a printed line or series of dashes/lines on the positive side.
iii. A red wire or a wire of a different color than the negative wire is applicable on one side (most often, red and black are necessary)
iv. One wire is copper-colored, while the other is silver-colored.
v. Slight positive (“+”) symbols and size information may be printed on the positive wire.
vi. The positive side’s insulation is imprinted or molded with a molded stripe.
vii. Imprints are the most difficult of the five types to spot, so you’ll need to look intently under good lighting at times. Additionally, at times, positive wires with a “+” print can be challenging to discern.
Frequently asked questions
- How can I test an 8-ohm speaker?
- 8-ohm speaker.
- A capacitor.
- Digital multimeter.
- Source of current such as a generator.
There are three methods you can use to test your 8-ohm speaker, and they include;
I. Using a digital multimeter
To begin, make sure you have the digital multimeter in place. Configure the digital multimeter according to the required settings. For instructions on properly setting up the device, consult the product’s guide. The parameters can be under the resistance settings.
Check the 8-ohm speakers and cables’ consistency by connecting a single wire to both the +ve and –ve terminals. Solder the positive and negative terminals of the wires to the digital multimeter. If there is an emission of a constant sound, the multimeter will not record any readings.
After finishing with the speaker, move on to the capacitor. The procedure necessitates the use of a digital multimeter and a capacitor test configuration. First, connect the two connections, a positive electrode to another positive electrode, and conversely. There are some measurements if the capacitor is correct, but if not, the capacitor is incorrect.

II. Attach the volt battery to the speaker.
Make sure you connect a source of electricity and that to your speaker. Attach leads of the speaker to your 8-ohm voltage battery. Ascertain that the positive charge corresponds to the positive lead and vice versa.
After joining, there is an immediate response in pulse production. If the speaker has a pulse, it is in good working order and is performing as expected. If not, look into the problems with the 8-ohm speaker. Try to fix them based on the source of the issue.
Understanding the colors of the 8ohm speaker is very effective in that it helps you perform the wiring process successfully. Luckily, the article provides some guidelines on connecting the wires without causing any harm.
Finally, pay more attention to the tools you are using. First, ensure the wires are in good condition before connecting them to the 8ohm speaker. Also, seek help if you cannot carry out the process on your own.
