If you have ever been looking for how to install 4 channel amplifier, there is a solution. Here we provide a step-by-step guide and installation guide that you can use.

Here we share how to install 4 channel amplifier without using any kind of professional tools.

In this guide, we will be covering how to install a 4 channel amplifier. We will be using a very simple method to show you how to do it.

Whether you need to amplify an existing 3.5 mm audio jack or want to use this amplifier for a speaker, we have the right guide for you. So let’s begin the discussion.

Steps To Install 4 Channel Amplifier:

Following are the simple steps that you should follow to install 4 channel amplifier in a short time. 

STEP 1. Get Your Components Ready:

To start, you’ll need a couple of different items. Here we will mention all the equipment that you need during the installation process. We will start with the amplifier. So let’s review these items.


I recommend the Pioneer DLA-X4002. It’s inexpensive, it has 4 channels, it has built-in subwoofers (optional), and it’s an amp with no limitations.


Next, we need our subwoofer. This will have to be a separate purchase because we’re going to need to make some modifications to it to make it work with our amp. You can use any subwoofer, but I found this one to be best because it has built-in subwoofers that come with the speaker. They will help save space in your room and they’ll fit with my design better.

Amplifier Power Cord:

Next, you’ll need your amplifier power cord. You can use whatever length you want, but I recommend you get at least an 8ft cord. This gives you flexibility if you need to reroute the cord around your room. You might even want to get a longer power cord.


Finally, you’ll need a switch or something that will turn on your amplifier so you don’t have to touch anything when playing music. The only component that comes standard is the input button, but that doesn’t matter much to our setup.

STEP 2. Place Your Speaker on the Ground:

Now that all of our components are assembled, it’s time to set them up. This is how we’ll place our speaker on the ground. We’ll place the speaker horizontally in the center of the room. It doesn’t matter which speaker we place first as long as they’re facing the same direction.

Place your amplifier in front of your speaker. Place the subwoofer behind the speaker so that the subwoofer is parallel to the ground. The speaker should be flush with the subwoofer.

STEP 3. Connect The Power Cord:

Now that the speaker and subwoofer are set up, it’s time to connect the power cord. The power cord can be plugged directly into your amp or subwoofer. If you plug it into your amp, you’ll get better sound quality because the subwoofer will power both the speaker and the amplifier. If you plug it into the subwoofer, you’ll get more bass because the subwoofer will power the speaker.

STEP 4. Turn On Your Amp:

Now that everything is ready, it’s time to turn on the amp. If you are using a switch to turn on your amp, turn it on. You may have to move the switch to make sure it’s in the correct position.

Next, connect your amplifier power cord to the input button on your amplifier. This will turn the amplifier on.

STEP 5. Connect Your Speaker To Your Amplifier:

Once the amp is turned on, we can connect our speaker. For best results, we want to get the best possible audio from our speaker. We do this by connecting them. First, place one end of the speaker’s cable into the amplifier’s speaker. This connects the speaker to the amplifier. Next, place the other end of the speaker’s cable into the speaker itself. This connects the speaker to the subwoofer.

STEP 6. Test The System:

Now that we’ve connected everything, it’s time to test it out.

If your amp has a separate volume control, set it to 100%. Otherwise, you may find the volume too loud. If so, you can either adjust the input gain or use a separate volume control for the subwoofer. I recommend the latter.

If your amplifier doesn’t have separate volume controls for each channel, make sure the volume is set to 100% on all four channels.

Next, adjust your speaker and subwoofer’s volume to match the volume of the amplifier. You’ll get the best results if the volume is roughly the same on both items.

This concludes the installation of our amp.

Wrapping It All Up:

An amplifier is an electronic device that can boost the volume of sound. It is a common feature on modern cars and it’s a simple way to improve the volume of a speaker without adding clutter.

This is an incredibly handy device to have because it lets you hear music louder without wearing earphones.

As long as you can reach the power and audio connections inside the car, you’ll be good to go.
