A four channel amplifier has proved to be an integral part of most stereo systems nowadays, but you need to have a good understanding of what a four channel amplifier is so you can make good use of it. You should know how to wire a 4 channel amp to 4 speakers and a sub if what you want to get from your car stereo is good sounds.
It is also crucial that you figure out if you want to work with a four channel or a two channel amplifier, but what we want you to know is that wiring a four channel amplifier to four speakers and a subwoofer isn’t difficult as so many people have described it to be. Knowing the right steps to take is what is the most important in this case.
Knowing what a four channel amplifier is will help when it comes to wiring it a four speakers, but amplifiers are generally designed with the purpose of enhancing sounds coming from your speakers. The fact that a four channel amplifier comes with two additional channels is one of the features that makes it unique.
These two extra channels makes sure sounds gets amplified or enhanced, but there is something you need to watch for closely when you are out shopping for an amplifier. This is figuring out what an amplifier’s minimum impedance rating is all about. Identifying the minimum impedance rating of an amplifier as it can be seen right on the amplifier.
How To Wire A 4 Channel Amp To 4 Speakers And A Sub
The minimum impedance rating of an amplifier gives you an insight of the speaker load that can work with the amplifier, and you might face some electrical problems if you connect a speaker with a heavy load that an amplifier cannot work with. This simply means the amplifier doesn’t have the capacity to withstand the power of the speaker.
This ends up causing overheating in the amplifier, and might eventually cause it to blow up. In most cars today, you are going to find not too integrated and heavy duty speakers or sound systems. Most stereo devices installed in cars are designed to handle about two ohms per channel, but bridging the electrical wiring aids in taking up 4 ohms.
In addition, you are going to find two different channel types in speakers. Below are some of the facts you should know about the channels;
Series Connection – This is the type of connection where amplifying power supplied gets divided between two speakers, while the speaker impedance adds up.
Parallel Connection – Parallel connection on the other hand is the type of connection where same amount of power supplied by an amplifier is present in the speaker, while the two speakers get to share the speaker impedance.
When it comes to wiring a four channel amplifier to four speakers and a subwoofer, you need to make the series and parallel connection. There are people that still find bridging confusing, and they do not know if bridging is important when doing this or not. This is what we will be talking about next in this detailed article.
Bridging And Its Importance
Bridging can also be described as mono mode, and it will interest you to know that this feature is present in several amplifiers today. Connecting two channels will ensure that you enjoy high amounts of power, but this power cannot be truly enjoyed of what you are making use of is a single channel speaker.
An amplifier has a push pull scenario inside of it when it comes to bridging, and it will also interest you to note that bridging can be done mechanically. The result is a signal that has two channels opposite each other, and the speakers you are going to find in this setup are the left and right speakers. Below is the benefit of bridging.
If you are a lover of high metallic sounds then this feature called bridging is the best for you. The main purpose of bridging is to ensure that you wire high powered speakers and subwoofers with ease, and when it comes to wiring a 4 channel amp to 4 speakers and a sub, bridging is the first necessary step to take.
Here are the steps involved when you want to wire a 4 channel amplifier to 4 speakers and a subwoofer.

The wiring or connecting of channels from each front speaker terminal to the speaker is the first step you must take, and this makes it possible to tie both speakers with a parallel connection. You will obtain impedance of 2 ohms on every channel, and wiring the subwoofer to the rear channel is the next step for you to take.
You can do this via connecting the left terminal with the positive end, and the right terminal with the negative end.
This steps is similar to the first step taken, and this connection is made possible when you make use of a parallel connection in connecting the speakers. You will be open to other options when you are working with a subwoofer, and you can opt to join either a single 4 ohm or a dual 4 ohm sub.
The parallel connection is also involved in this step, and this makes it possible for you to obtain 4 ohms on every channel. Connecting speakers with resistors is the only different approach you will take in this step, and this is necessary in providing protection against unforeseen electrical hazards.
The role resistors have to play in this step is to ensure that circuits do not heat up and eventually blow up.
The Benefits Of Using An Amplifier
Having an amplifier as part of your sound system is a very huge blessing as we all know, and this is because they have the ability to enhance your listening experience by turning it into something pleasant. You will enjoy crisp and crystal clear sounds when you pair an amplifier with your sound system.
Amplifying compressed and weak signals is the role an amplifier is designed to play, and all of this will make sure you get the best of sounds no matter what you are listening to.
