You can get a car amplifier and a subwoofer at low price rates. So we know you’ll want to learn how to install them quickly and easily.

So let’s dive into this easy way to install the car amplifier and subwoofer in your car.

Installing The Amplifier:

If you’ve ever tried to install a car amplifier or a subwoofer in your car, you know that it’s not as simple as it sounds. It is a difficult job that requires lots of patience and time.

Let us first talk about installing the amplifier and then we’ll talk about the subwoofer.

For installing the amplifier, we’re going to need a

  • Drill
  • An oscillating tool
  • An amplifier wire
  • A power adapter
  • A 12V DC connector, and a few tools

Let us now take a look at how to install the amplifier.

Step 1: Install a Power Amplifier

The first step is to install a power amplifier. The power amplifier will be used for playing back music from CDs, MP3s, or any other audio device.

Step 2: Select a Speaker

It is very important to choose the correct type of speaker that will fit into your car. You need to select the type of speaker that will allow you to use the amplifier and subwoofer that you purchase.

There are different types of speakers that have different characteristics, and they have different requirements for the installation. If you have a car with an air vent, there is a difference between speakers.

The speaker that comes with your vehicle is usually placed in the trunk area. If you want a better sound, you can install a speaker in the headliner or dashboard.

Step 3: Set up an Audio System

The main thing you need to do is to figure out what kind of audio system you have in your car.

This is a pretty simple process and it requires only a few steps. First of all, find a schematic diagram of your car and note down the type of audio system you have.

Next, find the radio and the CD player and check which wires are connected to these components.

If the components are not wired correctly, you can connect the wires by hand or use a simple wire splicing kit. However, if the audio components are already wired, you can skip this step.

If your car has a stereo with speakers on the dashboard, you can also set up the speaker system. If it does not have a separate speaker system, check your vehicle’s owner manual.

You need to get your car’s stereo speaker system up and running with the right settings.

Step 4: Make Adjustments to the Speaker’s Alignment

Once you have aligned the speaker with the center of the speaker port, check if it’s working fine or not. If the sound is coming from the speakers or not, then, it’s an issue with the speaker. So make a note of it. If the sound is coming from the speakers but it is very loud then, it may be a problem with your speaker.

To figure out whether it is a problem with the speaker or not, try to play your favorite music. If the music is really loud and full volume, then it’s an issue with the speaker. If it’s not loud, then it is a problem with your audio system.

The more you listen to the music, the louder the music will be, so you will be able to understand whether the sound is coming from the speakers or the audio system. If the sound is coming from the speakers, then it is a problem with the speaker. If the sound is coming from the audio system, then it is a problem with the car.

Step 5: Connect the Amplifier

Connect the amplifier to your stereo system by using the following steps.

  1. Plugin the amplifier first.
  2. Open the back cover of the car amplifier.
  3. Put it on the back panel of your car.
  4. Now connect the wires from the amplifier to the back panel of the car.
  5. Connect the wires from the subwoofer to the back panel of the car. You mustn’t disconnect the wires while connecting them. Otherwise, you will not be able to adjust the volume properly.

Step 6: Test the Car Amplifier

The next step after you’ve installed the car amplifier in your car is to test it. You should test it before and after you install it on your car. This is because there is a possibility of some issues with the connection between the amplifier and the car.

If the amplifier is not connected properly or if the wires are connected wrongly, then there is a chance that it might not work at all. In such cases, the best thing to do is to check and fix the problem by yourself. You can also contact a professional for fixing the issue.

Installing the Subwoofer: 

It doesn’t take much effort to install a subwoofer, so you can have it installed quickly without having to spend hours reading a manual.

Most of the subwoofer’s parts are small and easy to place on the dashboard. Following are the easy steps that you should review to easily install the subwoofer.

Step 1: Install the Sub and Connect the Speaker Wire

You need a subwoofer that has an “RCA” connector. It should have a power connection, volume control, and a ground connection. You need to install a power cord from your house to the sub. Many types of power cords will fit the subwoofer.

Once you have a subwoofer installed, you need to connect the speaker wires to the sub. In most cases, there will be a set of speaker wires for each speaker. To get the best sound quality, you need to connect the speaker wires of each speaker to the sub.

Step 2: Measure the Position of your Car Seat or Floorboards

The first step is to measure where your car seat is located. To do so, go to your car seat. If you have an OEM car, then it will look like it is bolted to the floor or something. Otherwise, if you have a car seat, it will have a bracket or something else to hold it on.

In the second step, measure the position of the car’s floorboard, such as where the carpet meets the actual flooring. You can find out by looking at the floorboard where there are holes for bolts, and you can take that measurement too.

If you are looking for a cheap way to install your car amplifier and subwoofer, then you don’t need to worry about this step.

Step 3: Wire in Place

To wire in place, you just need to take the wires from the amplifier that come with the box and place them at the bottom of the trunk. Just make sure not to touch anything on the floor.

Once you’ve done that, you should put it inside the trunk so that the air is pushed towards the speaker. After you’ve done that, just plug the wires into the subwoofer.

Step 4: Run a Few Tests 

This step is important before you do any major work. If you’re not careful, you can damage your car speaker system by running the wrong wire from one place to another.

You need to run the wires from the subwoofer to the amplifier. Don’t try to connect it directly. It might damage the amplifier.

To test if your wire connections are right, turn on the car amplifier and listen to the car speakers. If you hear the music too loudly, you’ve got it wrong. You need to move the wires so that they won’t be near the headrest. If you still can’t hear the music clearly, get a professional to do it for you.

The Bottom Line:

When you want to enjoy the music you like in your car, whether you’re listening to your favorite bands or playing your favorite songs, you need to have your sound system setup correctly.

It’s a bit hard to understand because it involves electronics. However, the most important thing to remember is that all of these parts are connected.

If one of them doesn’t work right, then all of the other ones won’t work. So, you must install them all correctly to experience great audio output from your car.
