Can I Add An Amp to My Factory Stereo

When the stereo system of your car doesn’t provide you with a clear and crisp sound, most of you might want to add an amp to it. 

Because an amplifier enhances the voice quality.

This is the reason many people have the question:

Can I add an amp to my factory stereo?

Yes, you can add an amplifier to your factory stereo system. Although it won’t have preamp outputs to pass audio signals to the amplifier, Many amplifiers offer speaker-level inputs, which let you connect to the car’s speaker wires and pick up the signal. Additionally, most amplifiers include a DSP (digital signal processor) to enhance sound quality.

What’s An Amplifier?

Hearing aids are equipped with tiny parts called amplifiers that allow voices to be heard louder. Also, you can plug large black boxes into electric guitars to raise the roof and use audio equipment to drive your loudspeakers and augment distant sounds. 

An amplifier can also be added to the car stereo system to enhance the sound quality of the speakers.

This is the reason many people ask whether or not they can add it to their car’s factory stereo system.

Can I Add An Amp to My Factory Stereo

Can you hook up the amp to the factory stereo? 

Yes, you can add it to your stereo system with ease and without having any sort of issue. If you decide to do it yourself or hire an expert, make sure the amp is connected to your stereo system.

You’ll learn how to add it later in this article. But, first, let’s look at some other aspects of amplifying and how it can be used in conjunction with your car’s factory stereo system.

When Should You Add an AMP to Your Stereo System?

There isn’t a specific time to do so. So, whenever you feel like adding it to the system, just add it. 

It might also be a good idea to consider adding a subwoofer amplifier as well as a great subwoofer to your system if you wish to increase the bass presence to the level you desire.

When You Shouldn’t Add AMP to the system?

It would be best not to add the amp in some situations. Let’s look at these situations.

  • There is no need to add an amp to the stereo system if any of the speakers in your car are broken. Because, even after adding it, you won’t be able to fix the poor sound quality. So, you’d better get your speakers fixed than install an amp in your car’s sound system.
  • Premium amplifiers are factory-installed on your system. (Before installing a new amp, the present amp must be bypassed.) So, firstly, you’ll have to bypass the current amplifier before adding the new one.
  • Your car must have been manufactured before the year 2000. There might be too many old wires in the system if you try to add an amp to it. (The speakers and/or wiring may be old and brittle.) This may make adding an amp impossible.
  • You shouldn’t add an amplifier to your car’s system if the radio is broken or doesn’t work. Even after adding the amp, the radio will still produce poor sound quality because it is faulty itself.

So, these are the situations where adding an amp to your car’s factory stereo system is unnecessary.

What Are The Steps To Add An Amp To Your Factory Stereo?

Let’s add an amplifier to the factory stereo system now. But, before I take you to the steps, let’s see what tools you’ll need for the process!

Things You’ll Need!

  • Amp installation kit
  • Universal back straps
  • Wire cutter/stripper
  • Electrical tape
  • A plastic bowl (to hold screws)
  • Bojo trim panel tools
  • A clean cloth
  • Torx driver
  • Flashlight

Steps To Add An AMP To Factory Stereo System!

  • The importance of your safety cannot be overstated. It is therefore necessary to unplug the negative connection of the automobile battery before doing anything else.
  • Put the amplifier in the car’s trunk, which is the safest place to add it.
  • An amp installation kit (red) should include the power cable and all the other wires necessary for this job. Let’s begin by bringing this wire through your car’s cabin and attaching it to the positive terminal of your battery. Afterward, extend it to where you’ll install the amplifier.
  • Connect this wire to the chassis near the amp using a bolt or nut. Using a screwdriver, Bojo trim panel tools, or a paint scraper, remove any debris that would prevent this wire from being securely fastened to the chassis.
  • Now, you have to determine the rear speaker’s wires carefully. Using a stripper or wire cutter, separate the positive and negative wires. A speaker line should be connected to each striped wire and taped shut. It is now necessary to connect these wires to your amplifier’s speaker-level terminals; each wire must be connected properly.
  • Connect the speaker wires to the amplifier’s speaker outputs and the subwoofer or speakers; again, these wires need to be correctly connected.
  • Then, connect the ground wire and the power wire to your amplifier. Currently, all that needs to be done is to connect the ground and power wires to the amplifier inputs. It is important to secure each connection properly.
  • The last step is to reconnect your battery terminal and ensure that it is securely connected. Taking out the battery will allow you to inspect the wiring if your amplifier is not functioning normally.

That’s it.

Final Words!
