The speaker system that comes standard in most new cars is often bad. Fortunately, in addition to the loudspeakers available on the market being a reasonably cheap way to improve your car's sound, are also, in most cases, easy to install (although the large number of speakers available on the market mean that some will be easier to install than others). See the first step below to start learning

How to Install a New Set of Speakers

See the stereo you will be installing your new speakers on. Some devices are simple audio systems that have a limited wattage and only 2 or 4 channels. So using 100 watt speakers or using 8 speakers or more will not make sense. Trying to use too many speakers can cause your sound quality to decrease or even damage the appliances.

Check speaker dimensions from the factory to minimize necessary modifications to install the new ones. Speakers are sold in different shapes and sizes.
So when planning a speaker replacement, knowing if the original was oval in measurements 6x9" instead of a 4" diameter round will help when purchasing.

Take Quality of the Speakers Into Account

Speakers with composite or fabric cones are noticeably better than those made of paper. The ones with ceramic magnets permanent magnets will perform better than those with electromagnetic magnets with the same strength level.

Choose the speakers with the fairings you like. You will find many styles and different colors of fairings in the same price range, so it makes sense to choose the ones that you like more.

See the electronic characteristics of your speakers. Some have resistors in series to prevent static and interference. Some allow you to make a call on a series circuit configuration to allow you to connect woofers and tweeters wherever you need. There are models that can only be connected to the terminals to maintain the impedance correct in the system.

Take into account the strength requirements, because this will have an effect on the wiring. High wattage speakers may not work with the car's original wiring. Replacing this wiring with a larger gauge takes work, since the original wiring of the car is well hidden and in places difficult to access.

Make Sure the Speakers You Choose Fit Your Car.

The majority of speakers will fit into the factory speaker spaces, while some will need minor modifications, such as installing a bracket or drilling a new hole for screw, etc. Take this into account when buying new speakers: the difficulty installation processes for speakers of different sizes or shapes can vary.

Keep in mind that most speaker manufacturers offer online tools to establish which of your products will best fit your car.

Disconnect your car battery to prevent electrical damage. Like almost all types of electrical work, you need to protect yourself and the electrical system before starting.

Disconnecting the negative battery terminal will prevent the risk of injury caused by electrical shock or damage to electronic equipment in the car caused by short circuit, so please be sure to disconnect the negative battery terminal before tampering with the car electronic circuit.

Remove the Speaker Panels or Grilles.

Almost every speaker inside a car will be covered with some kind of protective panel or grid. Before the high-speaker can be modified or replaced, that barrier must be removed.

Remove the grid with a suitable tool, such as a screwdriver, removing any screws that were holding the grid. Remove the factory speaker, note that the loudspeaker is normally connected to a harness/wiring. Be careful not to break it when removing the speaker. you may have to unscrewing more than a small screw or removing any adhesive foam or glue that are holding the speaker.

Connect the new speaker to the car's electrical system. Generally, connecting your new speaker is simple, just connect your speaker wiring to the car wiring.

However, if your car does not have this type of simple connection, you will have to connect your speaker using a solder wire connector or a crimped connector

Test the speaker. Now that you've connected your speaker, it's important to test the connection, so that you don't have to waste time in the future to fix a problem.
Reconnect the battery negative terminal and turn on the car stereo. Listen to the sound coming from your new speakers or watch for visible vibrations at high volumes. If your speaker does not work, there is a problem with the electrical connection.

Attach the new speaker. When you're sure your speaker works correctly, secure it in the appropriate location on the door or panel.

Reassemble all speaker panels and grilles, when all components of your new speakers are installed, tested and secured to the car, you can reassemble any speaker grilles or panels that you had to remove to install the new speakers. Save all the screws you had to remove to get the grille off or panel to be able to secure them correctly.
