One of the integral part of every stereo system today is a four channel amplifier, and it is very essential that you have a clear understanding of what a four channel amplifier is if you want your car to have a high quality stereo installed inside of your car. You should also have an idea on how to wire a 4 channel amp to 4 speakers and a sub if you are a lover of good sounds, and you should also determine if you want a two channel or four channel amplifier.
The fact is wiring a four channel amplifier to four speakers a subwoofer isn’t as difficult or tedious as it might sound provided you have a good knowledge of what steps to take. The first thing you must know is what a four channel amplifier is before proceeding to carrying out the steps we have for you. An instrument that is designed to enhance or boost weak signals so you can enjoy pristine and high fidelity sounds is an amplifier.
What makes a four channel amplifier unique is the fact that it comes with two extra channels so sounds can get more amplified or enhanced, but there is a certain important factor that should be carefully considered when you want to go out and shop for an amplifier. One factor you must look out for is the Minimum Impedance Rating, and you can find this present on every amplifier.
How To Wire A 4 Channel Amp To 4 Speakers And A Sub
This tells you the load of speaker that will work with your amplifier, and connecting a speaker that has a heavy load to an amplifier is likely to cause some electrical problems in your car’s sound system. What this means is the amplifier will not be able to hold or stand the extra load power the speaker comes with, and this will lead to overheating which in turn might cause the amplifier to blow up.
We make use of heavy duty and not too integrated sound systems in most of our cars today, and each stereo device that is installed in most cars nowadays is designed to tolerate two ohms per channel. If you bridge the electrical wiring then it can take up to four ohms. On the other hand, there are specifically two types of channels you will find in every speaker. Let us tell you a little about these channels below;
Series Connection – This connection involves the amplifier supplying power that is divided between two speakers, and the impedance of both speakers adds up.
Parallel Connection – This is the type of connection where the speakers gets the same amount of voltage delivered by the amplifier, while the speakers impedance is divided between each of the speakers.
Making both parallel and series connection is required if you want to wire a four channel amplifier to four speakers and a subwoofer. Most people do not know what bridging is or if it is important, and that is what we want to talk about next in this post.
What Is Bridging And How Beneficial Is It?
Also described as the mono mode, bridging is one feature that you will find already existing in amplifiers today. The connection of two channels makes it possible for you to enjoy more amount of power, but you cannot enjoy this power if you are making use of just a single channel speaker. There is a push pull scenario present in an amplifier when talking about bridging, and all of its settings are mechanically done.
What you will get is a signal with two channels that are opposite each other, while the left and right speakers are the two channels that you can find in this setup. Now, let us show you how beneficial bridging is;
Benefit Of Bridging
If you are the type of person that is fond of high quality metallic sound that you will enjoy the inbuilt feature called bridging. Wiring subwoofers and high power speakers in your car with ease is the main purpose of bridging.

Steps On Wiring A 4 Channel Amplifier To 4 Speakers And A Sub
The bridging of the amplifier is the first thing you must do if you are considering wiring a four channel amplifier to four speakers and a subwoofer. After doing this, carry out all of the steps we will be mentioning below;
The first step involves connecting or wiring channels at the front of each speaker terminal to the two speakers, and this mean being able to tie both speakers using a parallel connection. Doing this guarantees that you will have a two ohms impedance on every channel. After doing this, proceed to wiring the subwoofer to the rear channel. This is done by connecting the negative end to the right terminal and the positive end to the left terminal.
The wiring involved in step two is the same as the wiring involved in step one, and you can make the connections possible by connecting the speaker using the parallel connection or combination. However, there are several options open to you when working with a subwoofer, and you can also consider joining a dual 4 ohm sub or a single 4 ohm sub.
This step should also involved parallel system of connection for the speakers so you can be able to to obtain the four ohms every channel requires. The only different thing you have to do in this step is to connect the speakers with the resistors so as to ensure the wiring are well protected from unforeseen hazards. The role the resistors play is to make sure that the circuits do not overheat or blow up.

Benefits Of Using An Amplifier
Just like we mentioned earlier, amplifiers are a blessing to every sound system. They are capable of shaping your listening experience, making it easy for you to enjoy crisp and crystal clear sounds. Strengthening weak signals and also amplifying compressed signals is what an amplifier is designed to do, and trust this process to make your listening experience memorable.
What we want to leave you with is wiring a four channel amplifier to four speakers and a subwoofer is very powerful, and the reason why you should not miss out on adding a subwoofer is because it makes bass to sound very crisp and punchy.
