Quality sound output is only enjoyed by people who excel at wiring and balancing components. Speaker wiring to an amplifier can sometimes be challenging, especially if you have more speakers than the channels supported by the amplifier. This article helps you connect 8 speakers to a 4 channel amplifier. For example, you can connect 8 door speakers to a 4-channel amplifier.
To connect 8 speakers to a 4-channel amplifier, you can connect every 2 speakers to create 4 combinations of 2 speakers each. one. You can then connect this to all 4 channels. However, this will increase the load on each channel, so reduce the gains. This will also be half the impedance. For example, if you’re running two 4-ohm speakers on each channel, you’ll need an amplifier that can drive a 2-ohm load. Alternatively, run each pair in series instead of in parallel.
What is a 4 channel amp channels?
4-channel amplifiers are designed to conveniently power the four standard speakers in a car system. Therefore, they are crucial, especially when you need specific amplifiers for custom installations in your car. Plus, they make it easy to switch or connect the different channels for some connections, especially when you have more than 4 speakers.
If you have a 4-channel amplifier, the output terminals should be configured as shown below:
Channel 1
Channel 1 of the amplifier has two terminals: the positive and negative terminals. The first terminal is positive, while the second is negative.
“A” (positive)
“B” (negative)
Channel 2
East The channel has a configuration similar to channel 1. The terminals are marked as:
“C” (positive)
“D” (negative)
Channel 3
This channel also looks similar to channels 1 and 2 in the setup. Also, the terminals are the same.
“E” (positive)
“F” (negative)
Channel 4
Channel 4 is the latest in 4 channel amp. It has two terminals similar to the other channels. Similarly, the positive and negative terminals are placed in the same way as the previous three channels.
“G” (positive)
“H” (negative)
This channel and terminal description will help you correctly connect all 8 speakers to the amplifier.
Can a 4-channel amplifier drive 8 speakers?
A 4-channel amplifier can drive up to 8 speakers. If wired correctly, the amplifier will deliver up to twice the power output.
Although you can achieve both series and parallel connections, parallel connection offers the best performance. A 4 channel amp will comfortably work with 8 speakers. However, you must ensure that the wiring process is done without errors to avoid damaging the amplifier.
How to Connect 8 Speakers to a 4-Channel Amplifier
Hooking up 8 speakers to a 4-Channel Amplifier can be a great experience if you know the steps to follow and have the right tools.
You can adopt serial or parallel connection methods as we already mentioned. Whichever method you choose, you will need to connect 2 speakers per channel. Here are the tools you need for the connection:
- High-quality speaker cables
- Electrical tape crimp tool
- RCA adapter cables
- Ohmmeter
- Wire stripper
- 4-channel amplifier
- 8 working speakers
Serial connection
Having a serial connection is easy and safe. In this case, one of the speakers serves as the connection point for all the other speakers. One speaker will connect to the next in a linear pattern.
Step 1: Strip the Wires
Cut both edges of the wires to remove about ½ inch of insulation from the wires with a wire stripper. This should expose sections of the wire for easier connection.
Step 2: Attach the positive wire from speaker 1
Now, move the screw on the terminal 1, of channel 1 counterclockwise. Place the red wire from speaker 1 on terminal one, to the positive option of the first channel.
Step 3: Repair the negative wire from speaker 2
Place the black wire from speaker 2 on terminal two, to the negative of the first channel when you connected speaker 1.
Step 4: Connect speaker one to two
Now connect the negative terminal of speaker one to the positive terminal of speaker two. Tighten the screws and check the connection. Make sure the connection is secure and there are no loose wires.
Step 5: Connect Speakers 3 and 4, 5 and 6 and 7 and 8
Repeat the same procedure to connect the third and fourth speakers to the channel 2, the fifth and sixth to channel 3, and the seventh and eighth speakers to channel 8.
Parallel Connection
If you understand the concept behind of the parallel connection technique, it should be the easiest to execute.
Most car owners prefer to use parallel connections when connecting two or more speakers to an amplifier.
When speakers are connected in parallel, the ohm value of each speaker is divided by the total number of speakers in use to get the total impedance. For example, if all 8 speakers each have an impedance of 4 ohms, the total impedance is 0.5 ohms.
Follow the steps below to connect the speakers in parallel:
Step 1: Strip the wires
Cut both edges of the the wires to remove approximately ½ inch of insulation from the wires with a wire stripper. This should expose sections of the wire for easier connection.
Step 2: Connect the negative wires
Now, move the screw on terminal 1 , of channel 1 counterclockwise. Put the black wire from speaker 1 on terminal two, to the negative option (Terminal B) of the amplifier. Next, connect the negative terminal of speaker 1 to the negative terminal of speaker 2.
Step 3: Connect the positive wires
Move the screw on terminal 2 , of channel 1 counterclockwise. Place the red wire from speaker 1 on terminal 1, to the positive option (Terminal A) of the amplifier. Then, connect the positive terminal of speaker 1 to the positive terminal of speaker 2.
Tighten the screws and check the connection. Make sure the connection is secure and there are no loose wires.
Step 4 – Connect Speakers 3 & 4, 5 & 6, and 7 & 8
Repeat steps 2 and 3 to connect the third and fourth speakers to channel 2, the fifth and sixth to channel 3, and the seventh and eighth speakers to channel 8.
Advantages of parallel connection
- The process is simple
- The sound quality is impressive
Disadvantages Parallel Connection
- The overall impedance is lowered significantly, allowing the speakers to draw excessive power from the amplifier. This can cause overheating, especially when the system is running at very high volumes.
Frequently Asked Questions
What is the difference between a 2 channel amplifier and a 4 channel amplifier?
A 2-channel amplifier allows connection to fewer speakers, while a 4-channel amplifier will connect more speakers.
What happens when you connect more speakers than the capacity of an amplifier?
Connecting more speakers to an amplifier will increase the load. As a result, the temperature of the amplifier will rise, and the amplifier may be damaged in a short or long time if it gets too hot.
How do I test a speaker for the best quality?
The best way to test the best quality is by paying attention to the frequency. If the speaker reproduces the frequency clearly without adding or taking away detail, the speaker can be considered to be of excellent quality.
Can I connect 8 ohm speakers to a 4 ohm amplifier?
Yes, 8 ohm speakers can be used with a 4 ohm amplifier ohms. amplifier. In this case, two speakers are connected in parallel with each other to produce a total impedance of 4 ohms to match the amplifiers.
Conclusion
You now understand how to connect 8 speakers to a 4-channel amplifier. However, choose the method that will give you a quality result and make full use of the materials you have without breaking your budget. Another common wiring is to connect 6 speakers to your 4 channel amplifier. Check out this guide for more information.
