Wire A 4 Channel Amp To 4 Speakers And A Sub
The amplifier is famous as a tool that helps to tune the sound perfectly. You can boost or magnify weak signals to make the sound quality more realistic and quality.
This section will show you the steps to successfully connect a 4-channel audio amplifier with four speakers and one sub.
Scroll slowly, so you don’t miss any information.
Detailed evaluation of each detail before starting
We will show you how to check speaker impedance and minimum load. They are all essential details for those next steps of connection.
Speaker Impedance rating
In the first step, you should perform a detailed inspection and assessment of each part to see if it is eligible for the following connection steps.
What you are most interested in is the MIR or minimum impedance. It is an indispensable part that appears on the car audio amplifier.
What about the MIR? You can understand it is the minimum load capacity of the speaker and complete the car audio amplifier. Therefore, you need to consider this detail carefully to help create a better and more vivid sound.
On the other hand, connecting a speaker with a heavy load will cause some dangerous electrical problems that you cannot anticipate. When the audio amplifier is overloaded, it will result in an explosion due to overheating.
Therefore, you need to have transparent monitoring and evaluation to avoid encountering the above cases. They seriously affect your life, even your life.
Minimum speaker load
Determine Minimum speaker load
As mentioned above, we need to pay special attention to the minimum speaker load to make secure connections.
So the question arises, how much is the minimum speaker load for a 4-channel, 4-speaker, and one sub-audio amplifier connection?
According to research and feedback from several customers, the minimum speaker load in today’s car manufacturers is 2 ohms per stereo channel. Also, a minimum of 4 ohms will be required to drive the car audio amplifier perfectly.
However, that doesn’t mean you have to stick to the numbers above, and you need to be flexible about everything and consider your amp’s rating.
It is a significant step that determines the success of the connection that needs to be serious and correct.
Furthermore, to successfully make this connection, you must find out which method you should wire. Below, we present two standard wiring methods for this system.
- Parallel wiring: For a parallel connection, each speaker will receive the exact value of the car audio amplifier. However, the impedance part will be split between different speakers.
- Series wiring: This way, the impedances of the rear speakers add up, and the car audio amplifier supplies power to the speakers.
In general, to do the wiring of a 4-channel, 4-speaker, and one sub-audio amplifier, we need to make parallel and serial connections at the same time.

Conduct wiring for each system
Conduct wiring for three systems.
Before you do any wiring, it’s essential to find out how many systems you have to make and the characteristics of each. For this section, we will introduce three effective systems:
- System 1: Make a parallel connection of 2 speakers to get an impedance of 2 ohms x 2 + 1 subwoofer. In this system, you will get back 4 ohms at the terminals of the channels. This design is a sound system and is recommended for use with a 4-channel audio amplifier.
- System 2: Continue parallel connection for two speakers to get 2 ohms x 2 +1 subwoofer for 2 or 4 ohms impedance to the other side channels.
- System 3: Connect two rear speakers in parallel for 4 ohms + 1 wired subwoofer.
System 1, with the characteristics and quality it brings, we encourage you to choose it for your connections.
All you need with this system is to do the wiring in front of the terminal. That means you have to connect two speakers in parallel to get 2 ohms for each channel.
After successfully connecting the two speakers and a subwoofer, you connect them to the subwoofer and the rear channels.
The only way to make this connection is to connect the positive end to the left end of the audio amplifier and the opposing end to the right end of the amplifier.
Please note that each of the above connections should be careful to make the device work more efficiently. We recommend that you check every detail precisely so that the system can bring the desired results after connecting.
In general, the wiring of system 2 is similar to that of system 1. We need to make parallel connections for the two rear speakers and a subwoofer.
However, in system 2, you can choose two ohms or four ohms impedance for your subwoofer connection. Thus, helping you to diversify the impedance choice compared to system 1.
Alternatively, you can also refer to a dual four ohm or 4-ohm sub. Please consider carefully to make it suitable and highly effective for your device. The current connection will bring perfect sound quality for you in the future and now.
This system is less common than system 1, but they are all fine, and you should go for it.
In system 3, we also make parallel connections. The connections in this system help us get 4 ohms for each channel performed.
A rather prominent feature in this system is the connection of the resistor to the speaker wire. Thus, when resistors participate in the design, we will minimize the wire problems or explosions due to overheating.
Because the resistor we mentioned in the system is a particular type of resistor and has high heat resistance, therefore, with this system, you will not have to worry too much about fire problems.
Check to see if you got the results
The most confusing problem for you when reading through our information is probably how to test ohms.
We make straightforward ohms measurements with the help of a multimeter. Testing ohms is extremely simple with three steps:
Test with the multimeter
- Step 1: We need to put the multimeter into ohms mode. If the measuring device is capable of self-adjusting to ohms, that is good news for you.
On the contrary, if it cannot self-regulate, you must adjust. If you are not familiar with this adjustment, you can refer to it online or ask friends and family for help.
- Step 2: Measure ohms with a multimeter. It would help if you made sure the contact between the multimeter and the test device is meaningful. Only then can you get the results you need.
- Step 3: Read the result
If you still can’t figure out how to do the above steps, you should refer to this video tutorial. After just a few viewings, we are sure you will have a solid grasp of measuring ohms with a multimeter.
Besides checking the correct ohms, your next task is to recheck your connections after the wiring is done. You need to make sure they are ok and can test run.

Moreover, connecting them with four speakers and one sub will increase the sound quality, giving you a professional music space right in your car. It is truly remarkable.
In addition, with the audio amplifier, you will be able to establish many connections in many different ways. They can adjust the sound of all those devices to match as much as possible.
You can find more information through our frequently asked questions below. These are factual questions that we have carefully selected, and you can rest assured about them.
How many speakers can connect to a four-channel amplifier?
How many speakers can connect to a four-channel amplifier?
Most external amplifiers can power multiple speakers per channel.
For example, a 4-channel amplifier can power up to 8 speakers. If you wire it up correctly, you should be able to pull twice as much power out of the amp.
However, we think it’s still better to connect an audio amplifier with the correct number of speakers because this will ensure your sound quality. Limit connecting to multiple speakers as you most likely won’t get high-quality sound.
How many RCA cables do I need for a 4 channel amp?
As we mentioned above, you will need two RCA cables for a 4-channel amplifier.
Each RCA cable will have two signal channels, left and right for your front and rear speakers and left and right for your rear speakers. That way, you’ll get the sound quality you want.
Can you run six speakers on a four-channel amp?

Can you wire six speakers to a four-channel amp? Yes, a 4-channel amplifier can easily power six speakers.
However, this is not the best way because the demand is so great that the number of speakers you plan to connect can be on the amp.
You should not exceed the allowed connection level because it will cause several different problems. Even if you don’t know how to do it, it will affect you.
What amp do I need for two subs?
That means you will need a total impedance of 2 ohms for two subs on the audio amplifier. With such total impedance will help your device work better, be convenient for connection and achieve the effect you want.
There are many opinions that it is possible to achieve an impedance of 4 ohms for two subs. We think it’s a no-no, as they don’t fit your device. Not only that, but they also cause some problems during the operation of the device.
