Installing a speaker in a car is not easy, and it’s not a cup of tea for everyone. But it’s not so tricky that you can’t do it by yourself.

The speakers are also expensive, and you will manage your budget by installing them yourself. Before planning for installation, you may know everything related to the installation process.

There are two types of speaker installations:

Easy Fit Installation

Easy Fit speakers fit your factory speaker openings and use factory speaker grilles and brackets. An Easy Fit speaker will fit directly into the subsisting manufactory speaker opening. Sometimes, you’ll need to use a unique set of frames or appliances to install Easy-Fit speakers in your vehicle, or you may need to drill new mounting holes.

Modify Fit Installation

Speakers labeled as Modify Fit demand alterations like drilling new screw holes or cutting or filing metal, plastic, or press board. These installations are more complicated and need other tools and time.

Many questions arise in one’s head when planning to install a new speaker in a car stereo system. And it will be good to answer every question before starting a process. Before discussing the preparation and installation process, we answer some popular questions. Let’s check it out.

How much time is required for installation?

Every car has its installation requirement as per its design and model. Installation of speakers required a couple of hours to complete. It takes around one to two hours to building depending on the number of pieces of paneling that need to be removed. If the speaker is already installed in the rear deck, you need to replace it, and it will be easier because you don’t need to make mounting holes. Otherwise, making holes will take a lot of time.

Is there a possibility of installing speakers on any car’s rear deck?

These days, many cars come with pre-installed speakers in their deck. If you wish to install your favorite speakers in the rear deck of your vehicle, you need to replace them with the installed ones. Before buying new speakers, ensure the space available, so speakers must be perfectly set up. 

Also, check mounting holes for speakers; if holes exist, all you need to do is buy speakers matching their size. But if holes are not living, you need to cut holes for speakers as per their size requirement. Making fixes might be time-consuming and increase its installation time. Making holes in the car body may affect its warranty for new vehicles.

When adding speakers to the rear deck, is replacing the front speakers?

If you have already had front speakers installed in your car and, at the same time, you wish to add a speaker in the car’s rear deck, you do it so. Rear deck speakers give you a surround sound effect and make a massive difference in the overall sound quality of your car. Adding speakers in a back deck with front speakers already installed is a good idea to get a better music experience. It is recommended that all the speakers be of the same brand and be added or changed simultaneously.

I hope you get answers to all of your questions. Now, let’s move to the installation process, and preparations are done before starting the process. 

Preparing for Installation

When planning to install new speakers in a car, many questions arise. Some of the popular questions are answered before in this article. It is good to sort all doubts, answer all questions before installation, and prepare the necessary.

Selecting a new speaker :

Speaker selection is one of the main tasks, as the installation will depend on it. So it is necessary to select speakers according to your car model. Before making any decision, check the following points mentioned below, which help make the installation process more manageable.

Look at the stereo system you’re installing your new speakers on. Some systems are simple stereo audio systems with limited wattage and two or four channels, so 100-watt speakers or adding eight or further will not make sense. Trying to push too numerous speakers can get the quality of the audio to be lowered or damage the stereo.

Check the confines of the speakers so minimal variations will be demanded to fit the new bones. There are speakers of different shapes and sizes, so planning to mount a relief speaker, knowing if the original was a 6X9 inch round rather than a 4 inch (10.2 cm) round bone, will help choose the stylish fit.

Consider quality. Speakers with compound or fabric cones are generally noticeably better than those with paper, and ceramic endless attraction speakers will out-perform crack electromagnetic speakers at the same power position.

Select speakers with neat packages you like. You may find numerous different styles and colors of trim and covers in an analogous price range, and it makes sense to pick the bones that look good, not just sound good.

Look at the electronic characteristics of your speakers. Some have inline resistors to help static and crosstalk. At the same time, some allow wiring in a series circuit configuration to grant you to add woofers and tweeters where you need them, and some can only be wired terminally to maintain the correct system impedance.

Consider the power conditions of your new speakers as they will affect the wiring. High wattage speakers may not be suitable to perform with the plant wiring, and altering these to a more significant size may mean considerable work since plant wiring is concealed in hard-to-reach places.

  • Remove the bolts and send them away with the plastic rivets to reuse with the new speakers. 
  • Precisely pull the old speakers over and out of the sundeck, being sure not to pull too hard on the wiring. The speaker cables will be connected to the main wiring via a connector. These connectors will have a small plastic piece that you’ll need to lift as you pull them away. Do this step for both speakers. 
  • Installing the new speakers in the deck will reverse the first four-way ways. The first will be connecting the new speaker harness to auto wiring with the same draw. 
  • Once the wiring is connected precisely, place the speaker down into the sundeck and line up the pre-drilled holes. 
  • Using the being bolts, fasten the new speakers into the hinder sundeck. And also, ensure not to tighten these bolts tightly, as they can crack the plastic lip of the speaker. Do this way for both the left and right speakers. 
  • Place the aft panel over the hinder sundeck and fasten with the plastic rivets, pushing them down until you hear them snap. All the paneling should be flush, especially any corridor around the door frame.
