How to Wire a 4 Channel Amp to 6 Speakers — Easy Car Stereo Instructions in 2021
Home - Audiophile Hacks Many think that installing an amplifier in their vehicle is hopelessly complicated and best left to a professional. Keep in mind wiring a 4 channel amp to 6 speakers is not a good practice. The best strategy is to buy a 6 amp channel or connect 4 speakers with a 4 channel amp. However, it is possible to wire 6 speakers to a 4 channel amp. An increase in amp load puts your device hot, which is not good and may damage your amplifier. You can wire up 6 speakers to 4 channel amp either in series or parallel.
If you have 4-ohm speakers that audio buffs purchase mostly. When you connect 2 speakers on 1 channel, you connect 4 speakers on 2 channels.
The 4 speakers are wired on 2 channels, and you can connect the remaining 2 speakers on the other 2 channels. That means you have connected 6 speakers on 4 channels. Your stereo can become hot on 2 channels because of the double load.
When this is the case, you are listening at a high volume for a long time. Wiring 6 speakers to 4 channels in parallel allows you to get full power and high-quality sound.
However, it would be best if you do not listen at full volume for a long time. It will make your stereo hotter and eventually damaging your equipment. Wiring Series — 4 Channel Amp To 6 Speakers Another tip on how to connect a 4 channel amp to 6 speakers that is safer and reliable compared to parallel is by doing wiring series.
It is safer to wire in series for your stereo, but it may not give you an excellent sound when listening to music. When wiring 2 speakers of 4-ohm in series, it adds a load of 8 ohms on the head unit. This method is much lesser risky than in series You will have 2 speakers in series connecting on 1 channel. Now, 4 speakers are connected on 2 channels, and you can connect the remaining two speakers on the remaining two channels. That means you have connected 6 speakers on a 4 channel amplifier.
How To Wire 6 Speakers As mentioned in the above section, you can connect 4 speakers in 2 channels in either series or parallel. The question left now is which two speakers to wire in a single channel. If you have 6 speakers installed in your car, 2 are on the dashboard, 2 on the rear, and two on the sides. You can connect 2 side speakers with 1 channel and 2 rear speakers with 1 channel. You should connect the remaining 2 speakers to every single channel.
You need to understand a few things to wire four speakers and a sub on a single 4-channel amplifier. Not all car amps can bear speaker capacity down to 2 ohms. You need a few extra parts as well. Your amplifier typically shows an image of a 4 channel minimum speaker load Ohms rating.
Today, most amps come with a standard minimum of 2 ohms per channel in stereo, and when bridged, your unit has 4 ohms. Never wire an amplifier with a lower rating than the speaker load. Your amp will run hot and can damage your sound equipment.
Four-channel amplifiers have a minimum speaker load they can bear. Ohms or speaker impedance rating, also called the speaker load, is the electrical current force that the amplifier connects at the speaker terminals. Get more tips on wiring speakers. However, there are safety precautions that you must consider in both procedures. To get better sound quality, make sure to wire speakers properly so that it will not destroy your equipment and enjoy listening to music.
Keep in mind that wiring speakers in series are the safest method.
How to wire 6 speakers to a 4 channel amp?
Verdict What is A 4 Channel amp? A 4 channel amp is also known as a stereo amplifier. At a minimum, a 4 channel amplifier can power 2 speakers. It can as well power 2 subwoofers simultaneously without any restrictions or limitations in performance.
Why is it needed? In that case, 4 channel amp allows you to achieve this with ease. Another great benefit is that 4 channel amp makes it possible to connect two speakers and a subwoofer at the same time. Can I wire 6 speakers to A 4 Channel Amp? Yes, a 4 channel amp can easily power 6 speakers. However, this is not the best practice because of the excessive demand the number of speakers you intend to connect may put on the amp.
Ideally, it is expected that 4 speakers should be wired to 4 channel amp, and 6 speakers connected to a 6 channel amp for efficient and uncompromised performance. Nevertheless, wiring 6 speakers to a 4 channel can be done, and it is never out of option. How To Wire A 4 channel Amp To 6 Speakers DIY Connecting 6 speakers to a 4 channel amp is always a great experience, provided you know the basic things to do- the steps to take and the tools you need to achieve the intended result.
As discussed in the introduction, there are two techniques or methods that you can adopt while trying to connect your speakers to an amplifier. These are the series and parallel connections. Irrespective of the installation or connection technique you eventually settle with, you will have to connect 4 of the 6 speakers in 2 channels. Series Connection This technique is an easy and safe way of wiring 6 speakers to a 4 channel amp. The whole idea behind this method is that one of the speakers serves as the connection point for other speakers.
You will use wires to connect one speaker to the next one, following a linear pattern or arrangement. A wire is extended from one end of the amplifier, which is then connected to the first speaker, and then connected to the next.
The last speaker is connected to the other end of the amp. So, how is this done? Two speakers are connected or powered in series on a single channel. This means, 4 of the 6 speakers will be connected on 2 of the 4 channels. Then the remaining 2 speakers are then connected to the remaining 2 channels individually.
Speakers can be added and removed easily and safely without additional costs Disadvantages of channel connection The speakers pull lower power from the amplifier power is reduced , which may affect the sound quality Parallel Connection This connection technique is the easiest, provided you understand the concept behind the connection process.
This makes it the most preferred technique by most vehicle owners when it comes to wiring two speakers or more to an amplifier. This method requires using different wires to connect each speaker to the amplifier.
For instance, if you are connecting 4 speakers to the amp in parallel, and each speaker is 8 ohms, this gives us 2-ohm. You can also adopt this process to connect the 3rd and 4th speakers to the 2nd channel. Advantages of parallel connection The sound quality is impressive Disadvantages of parallel connection The overall impendence of the speaker load is reduced. This allows the speaker to draw an excessive amount of power from the amplifier, resulting in overheating, especially when operated at a very high volume.
Tools The following are materials or tools you will need to wire a 4 channel amp to 6 speakers. You need a top-quality speaker wire You need a digital test meter for voltage measurement You need two RCA adapter cables Get zip ties You need an electrical tape Get fuse and fuse holder in place Crimp tool Cost There are several brands of amplifiers on the market, and each of these designs is offered at a different price.
It is important to choose from any top-quality designs out there for the best performance and amazing experience. Some of these brands are positioned as premium. In contrast, some are positioned as mid-price. Time Installing an amplifier on your vehicle can last for about 4 hours, especially if you are conducting the installation yourself.
Suppose you are taking your vehicle to an expert for the amp installation. In that case, the time required to complete this process may be shorter. Why is my stereo hot? Although it is possible to connect or wire 6 speakers to a 4 channel amp, the best practice is to have 4 speakers connected to the 4 channel amp. When you have 4 speakers connected or wired to 2 channels out of the 4 available channels in parallel, this puts a constant load of two 2 ohms on the 2 channels if you operate the speakers at the highest volume for a long period.
If this continues, it is not healthy for your stereo. Your stereo will eventually break. While the parallel connection may not give the safety that the series connection offers to the stereo, the sound quality makes it a superior connection method.
How do I prevent my stereo from getting hot? Once the stereo is not operated at a really high volume, you have nothing to worry about. This is an effective strategy you can adopt to ensure your stereo work at a normal temperature at all times. What happens when you wire more speakers than the capacity of an amp? How do I wire my speakers to my 4 channel amp? Basically, you connect 4 speakers to 2 channels, and the remaining 2 speakers are connected individually to the other 2 free channels.
Suppose you have 2 speakers installed at the front of your vehicle, 2 speakers at the back, and the last 2 speakers on the sides.
In that case, the 2 front speakers can be wired to the first channel and the 2 rear speakers to the second channel. The 2 speakers on the sides of the vehicle can then be wired individually to the remaining two channels- each speaker connected to a single channel.
How do I test for or identify a top-quality speaker? Your speaker must also be solid or of great quality to ensure you get the best outcomes or results from your amplifier. The best way to identify or test for a good speaker is by paying attention to the frequency.
If the frequency is reproduced specifically and clearly without the addition or removal of any detail, such a speaker can be considered an excellent choice. We hope you now have a clearer and better understanding of what this process entails and how it works. So, feel free to explore- choose the best installation method that fits your needs and situation.
In case you are confused about which one to eventually settle for, you can try out the two connection methods and choose the one that gives the best feeling and experience. As much as the information provided encourages you to do the job yourself, we advise you have at least a basic knowledge of electrical work.
In case you have not engaged in any electrical works in the past, it may be a great option to consult an expert. Although this will cost you a few bucks, it is a safer option in this case.

How To Wire a 4 Channel Amp To 6 Speakers
How to Wire a 4 Channel Amp to 6 Speakers?
To install the wiring in your car you have to take out the dashes on the sides of your car so that it is easy for you to work your way from there. If you already have wiring for stock speakers, then you have to take them out of their location so that you can easily create a new wiring structure in your car.
Select the location for your car speakers Before diving into installing the wiring for your speakers, you must see where you will install your speakers in your car.
Well, there are not enough places to select if you have a simple car. Whereas, if you have an SUV, then you may have different choices for your selections. Most commonly, people try to install the speakers in the doors or the trunk of their car. We will suggest you the best location for your speaker so that you do not have to compromise any of the space in your car, especially the trunk of your car. The best way to wire six speakers in your car is to wire them in the doors and above the trunk.
You can wire four speakers inside the doors and two speakers behind the backseat of your car. So, you have to find or create a better enclosure for your speakers to mount perfectly. Wire with a proper architecture Now, you must be wondering that how can you wire 6-speakers with a 4-channel audio head unit. You may have heard of the series and parallel connection of the speakers.
We will give you a better solution for our problem with a parallel wiring of your speakers. So, as the head unit is out of the dash of your car, there are 4-channel ports located at the back of the audio head unit. You cannot install 6-wires on it directly. So, you have to follow a specific type of wiring structure to power your 6-speakers properly. Keep in mind that you must not use speakers which require high power to function.
How To Wire A 4 Channel Amp To 6 Speakers
Always use 4-ohm or less than 4-ohm speakers. Connect the two wires to the positive terminal and two wires to the negative terminals of the channel ports behind the audio head unit.
Now, the next step is to route these wires to the selected locations for the speakers. In connection with the series, a wire runs from one terminal of the AMP channel to one speaker, which is then connected to the other speaker, and the last speaker goes to the other terminal of the channel. The following steps will help you connect 6 speakers to a series of 4 channel amplifiers.
Step 1: You will connect the negative wire from speaker 1 to the negative terminal of channel 1 of the amplifier. Next, you need to connect the positive speaker from speaker 1 to the negative terminal to speaker 2. Finally, connect the positive wire from speaker 2 to the positive terminal of channel 1. Step 2: Connect the negative terminal on speaker 3 to the negative terminal on channel 2 of your amplifier.
To make a series connection, connect the positive terminal on speaker 3 to the negative terminal on speaker 4. You should connect the positive terminal on speaker 4 to the positive terminal on channel 2 of the amplifier.
Step 3: All you need to do is connect one speaker to the third channel of your amplifier. In this regard, you need to connect the negative terminal on speaker 5 to the negative terminal on channel 3. Connect the positive wire in channel 3 to the positive terminal in speaker 5. Step 4: Again, you must connect a speaker to the fourth terminal of your amplifier. To connect from Speaker 6 to Channel 4, just follow the procedure described above. The Benefit of connecting 6 speakers to 4 channel amplifier in Series Parallel connections are opposed here, connecting the speaker to the series does not increase the impedance load on the terminal.
That way, the connection to the series is more secure, especially if you keep playing loud music for extended periods. See also Are telecasters good for funk? The Possible Drawbacks of connecting 6 speakers to 4 channel amplifier in Series With the connecting 6 speakers to 4 channe l amplifier in series, the speakers are not free. If a speaker fails, they will all shut up. Again, the sound quality produced with the series connection is relatively low.
To figure out the total impedance of multiple speakers wired in parallel, you multiply together each individual impedance, then divide the result by the sum of the impedances. In other words, when the speakers have the same impedance, their total impedance, is the impedance value of one of the speakers divided by the number of devices. For example: Four 4-ohm speakers wired in parallel have a total impedance of 1 ohm.
Series Wiring In series wiring we wire the speakers one after the other — a plus of one to a minus of another. When speakers are wired in series, you add their impedances together to figure out their total impedance.
Adding speakers in series increases the overall resistance of the circuit. For example, two 4-ohm speakers wired in series add up to 8 ohms total. Each of which depends on a set of parameters including your overall setup, what amp you have and how many ohms the speakers are, not to mention the way you want to do the wiring …etc.
On a side note, the easiest way to have all these speakers up and running would be to wire the weakest speakers in terms of power handling dash speakers in our case directly to the headunit, and connect the remaining ones to the amplifier. A great way to connect all the speakers to one 4 channel amp is to have the rear deck speakers on two separate channels, and the front four speakers wired up running to the amp where the front left speakers are on the same channel, and the front right ones are on the same channel.
You can also put two pairs of 4 ohm speakers on a 4 channel amp in parallel giving it a 2 ohm load, and leave the remaining speakers as a 4 ohm load. Or the other way around — Pair up rear deck speakers in parallel 4 ohm loadand put the 2 pairs on the front 2 ohm load. Another way to hook up a 4 channel amplifier to 6 channel speakers, is to bridge it into 2 channel mode, and run 3 speakers on the right side in series per channel, and run the other 3 speakers on the left in series per channel.
Furthermore, you can run 2 pairs of speakers in parallel which would be 2 ohms then the other Pair of speakers can just be run normally off of the other channel. As a general rule of thumb, always check the impedance on the speakers and the minimum impedance on the amp. S: It must be noted that if all of your speakers are 2 ohms you would definitely need an additional amp since if run in parallel they would bring it down to 1 ohm, and that would ruin the amplifier.
