The first step will be to remove the rear panel that covers the rear deck.

On many cars, you can hunt around the edge of hard plastic, which is handy if you buy a trim removal tool. This will remove the plastic rivets that take place in the panel. Make sure to save them.

Once the back panel is removed, find the bolts that hold the current speaker to find what size plug you will need to remove them.

As with almost all types of electrical work, it is important to protect yourself and the electrical system before beginning. Disconnecting the negative battery terminal prevents injury or damage to the car’s electronics, so be sure to do so before handling any of the car’s internal electronics.

Filling the back like a filler

For systems designed to focus on the front soundstage, rear speakers often operate at a much lower relative level than the front one. Some people call this technique “backfill”. The intention is to provide a sense of spaciousness in the listening environment. The use of the rear speaker allows for division between systems with or without the rear speaker. The relative level of these speakers is important. Too much can start pushing back the soundstage.

Nothing is right or wrong depending on your soundstage location preference. What you like is the right choice. Your local mobile electronics dealer can work with you to design the system.

Speaker installation

Installing new speakers is the most cost-effective upgrade you can make to your vehicle’s audio/video system. Aftermarket speakers are not only relatively inexpensive, but also not difficult to install due to the free brackets, wiring harness, and detailed instructions that the company will send you when purchasing their speakers. Of course, every car is different, but let’s take a look at some of the most common speaker mounting locations and what you can expect when installing a speaker there.


The bass is not in eq. All aftermarket car stereos have the option to accommodate bass and treble. The first EQ slider controls the bass; this is usually a low number, such as 50 or 60 Hz. Keep doing what you want to do and stop until you hear the bass distort. Sometimes there is very little bass in the bass, so your 6×9 car speakers do not reproduce strong bass.

Test loudspeaker

Now that you’ve connected your speaker, it’s important to test the connection so you don’t have to waste time troubleshooting a problem later.

If your speaker is not working, it means there is a problem with your electrical connection.

After positioning the speaker correctly, hook it onto the connectors. If you removed the first subwoofer to cut a piece of metal, put it back in place and reconnect it to the amplifier. Finally, you need to test the speakers to see if they are working properly.

Installing a rear speaker isn’t particularly easy, but doing it on your own is definitely cost-effective. Workshops charge very little for any type of installation and you may not always be satisfied with their work.
