How long does it take to install a car stereo?(2024)

Last Updated on September 17, 2022 by John Robinson

Installing a car stereo is usually done by car audio professionals who have the proper knowledge and equipment. However, people who are familiar with the inner workings of a car can install a stereo in a vehicle without help from professionals. If a person is not a professional but knows enough about cars to feel comfortable doing it themselves

When installing a car stereo, there are many different things that need to be done. The car battery needs to be disconnected and later reconnected once the stereo is installed. A mounting system needs to be chosen and placed in the proper location so that the stereo sits properly and securely inside of it. Wires for power, speakers, and other items need to be connected to the stereo. The final step is connecting the new power source of the vehicle’s battery back into the car so that it will work properly with all of its electrical systems.

In my experience, most car stereos take about an hour to do the installation, and half that time is spent removing parts from the car’s dashboard.

Installation time depend on stereo type

There are several kinds of car stereos, and the installation time for each one varies. Factory stereos, which are installed in a car when it is manufactured, are usually the simplest to install. Aftermarket stereos, which are installed in vehicles that do not have a factory stereo, can be more difficult to install and usually necessitate some mechanical knowledge.

Car stereos are also divided into two types: single-DIN stereos and double-DIN stereos. A single-DIN stereo is the same size as a standard CD player and will fit in most standard CD player spaces. A double-DIN stereo will not fit in most factory speaker locations, necessitating the use of an aftermarket mounting system.

A double-DIN radio is twice the size of a single-DIN radio. As a result, they will not fit in most factory speaker locations without some modification. This is why aftermarket mounting systems are required for the installation of double din stereos. Double-DIN radios necessitate more work than single-DIN radios. Installation can take some time. Because there are two main pieces connected by cables about an inch or so wide, wiring a double din radio is more difficult.

The most critical aspect of the installation is ensuring that all of the wires are properly connected. This means that the installer must understand how the stereo works and what each wire does. If a wire is not properly connected, it can cause problems with the electrical system of the vehicle. Another factor that can influence installation time is the type of vehicle in which the stereo is installed. Certain vehicles have more complex electrical systems than others, making installation more difficult.

However, most people who are familiar with cars and car stereos should be able to install a car stereo in about an hour, excluding the time it takes to remove the old stereo.

A standard CD player is the same size as a single-DIN stereo. As a result, they will fit in most factory speaker locations without needing to be modified. Single-DIN car stereos are the most straightforward to install. All that is required is the removal of the old stereo and the installation of the new one. Wires are not required to be connected. However, a new mounting system must be purchased and installed in the vehicle’s dashboard.

This takes approximately 30 minutes. The time it takes to install a stereo is mostly determined by how quickly the old one can be removed and replaced.

The different parts of the car stereo and how much time each part contribute to the total installation time:

Overall, installation time is about an hour and a half when the process is done by a professional installer.

  • Removing the factory stereo: The factory stereo is removed by taking out the screws that hold it in place and sliding the stereo out of its location. This process takes about 10 minutes
  • Installing a bracket/adapter mounting system: A bracket or an adapter is installed in the factory location where the stereo was removed from. This part of the process takes about 15 minutes
  • Installing a wiring harness: A wiring harness is connected between the new vehicle-specific mounting system and the car’s battery, making this process quick and easy to do
  • Connecting wires to the car stereo: The wires for power, speakers, and other devices are connected to the back of the car stereo. This process usually takes about 30 minutes
  • Mounting the car stereo in the bracket/adapter: The car stereo is placed in the bracket or adapter and secured in place with screws. This step usually takes 10 minutes.

How to speed up the installation process?

There are a few things that can be done to speed up the installation process:

  • Installing a wiring harness: A wiring harness can make the connection between the car and the stereo quick and easy. This will save time when connecting the wires.
  • Having all of the tools necessary for the installation: This will help avoid having to search for a tool during the installation process.
  • Knowing how to connect the wires properly: If all of the wires are connected properly, it will reduce the chances of electrical problems with the vehicle.
  • Buying a car stereo that is easier to install: There are many car stereos on the market that are designed for easy installation. These stereos usually have fewer wires and no modification is required to install them.

While installing a car stereo can take some time, it is something that most people know how to do. If someone knows the basics about vehicles and electrical systems, they should be able to install a car stereo in about an hour and a half. However, if these factors are not considered, the installation process can take much longer than expected.

First time installation takes more time

The first time you install a stereo in your car, it might take you about two hours or even three hours. However, after that, when you have already soldered wires into the car’s electrical system and know what you are doing, you should be able to install the stereo in about half an hour.

  • Double check your radio bezel to see if it’s compatible with after-market radio installation. This may not seem important now, but you want nothing hampering the view of the screen!
  • Determine if there are any additional wires or features on your dashboard that need to be removed prior to installing the new car stereo.
  • Carefully measure out where you want the head unit to be installed in relation to both right and left side dash vents. You don’t want it blocked by anything else in front of it!
  • Organize all the wiring necessary for radio installation into one manageable bunch, which will make routing and connecting much easier.

Common mistakes people make when installing their own car stereos

Car audio systems are complicated, technical pieces of machinery. Installing one yourself is not always easy. Here are some common mistakes people make when installing their own car stereos:

  • Not having the proper tools: An installer needs to invest in high-quality tools for this job. The cheaper versions of these will not suffice. They will break shortly after purchase and leave you frustrated with your system installation down the drain.
  • Not making sure you have enough power available: Many people do not consider this before even starting to put their stereo in. Make sure you have an ample supply of power running to the spot where you are installing your radio.
  • Installing interior parts incorrectly: Some people install stuff like vents and speakers upside-down. It might look right at first, but it isn’t. The issue is that the parts are made to function in a certain way. It’s critical to install them correctly.


It takes a few hours to install a car stereo. The process is fairly simple and the installation only requires basic tools. In general, most people can complete this project themselves as long as they have some patience and time on their hands. An experienced mechanic might be able to do it more quickly, but those who are less confident should plan for about 3-6 hours of total time spent working on the task from start to finish.
