How Do You Install Car Speakers?

Installing car speakers is not as easy as “plug-in and play”. For starters, you must be sure your current audio setup is able to work with the speakers and some have limited channels from the stereo or the amplifier is not able to cope. Once you are sure that is not the case, you can go ahead and begin the installation, which is as followed:

  1. Check the dimensions of the speaker – The majority will be a standard size such as 6.5 coaxial speakers.
  2. Disconnect the battery – Before wiring anything in, there must be no current flowing through.
  3. Remove the grill or door card – You will need access in order to wire in the speaker.
  4. Disconnect the old speaker from the harness – There may also be foam you need to remove.
  5. Install the new harness and connect the speaker – One connected, ensure there is no movement.
  6. Test the speakers – Test all the speakers and ensure the whole audio setup is still all working
  7. Put everything back together – Once complete, test again.

This installation is a very basic setup and will follow closely to a straight OEM swap. However, many car audio enthusiasts may choose a custom setup for more bass and extra sound quality as per below.

How To Tell If Your Car Speaker Is Blown

Blowing your speakers can be a real problem, but at the right volume, any type of sound can cause damage. Here are some steps to check if the speakers in your system have been blown and need repair.

  • Turn on your car and insert a sound disk or mp3 that you listen to often. Play a song that you are familiar with so that you can accurately review the sound quality. Make sure that the song or sound is being played at the correct volume.
  • Listen for the distortion and try to recognize it. If you hear crackling, or the sound is muffled, then one of the speakers might be damaged. While the song is playing, try to discover differences. Look for a lack of range in the song or sound that is being played.
  • After the distortion has been confirmed, then look for the speaker that is damaged. If you have a pan system or a way of isolating sounds in the car, then use these controls to locate the damaged speaker.
  • Once the speaker is located, the next step will be to disconnect the speaker wires. After the wires from the speaker have been detached, connect them to a nine-volt battery and observe the speaker. If the speaker still works, then the speaker is fine, which means that there is a problem with the wiring.
  • Use a multimeter tester for a more accurate reading when checking the wiring. Check the OHMS, and if the reading is 1.0, then the speaker is not blown and it is something else that is the problem. If the reading is infinite, then the speaker is blown and needs to be changed.
  • Inspect the amplifier and see if it affects the sound. If distortion is heard, then that can mean there is a bad fuse or capacitor, and that your speaker is not damaged.
  • Check out the fuse box and see if all of the fuses are operating at their full capacity. Use a multimeter that is set to the “conductivity test” to check for this problem.

What Size Car Speaker Fits?

When you are deciding to install new speakers into your car, you need to make sure that they can fit. All the work will be for nothing if the speakers are not the correct size and you will have to cut into your door card in order to make them work.

So that you are not left disappointed, below are some tips so that you are not left frustrated:

  • Check the measurement markers for the inbuilt speaker brackets. This can make it easy to fit the new speakers into the old speaker’s slot. Not all speakers have these markers, it is best to check to see if they do.
  • Check the manual that came with the car for any information that can be useful for setting up the size of the speaker. Use the data in the charts provided as a guideline when trying to install the new speakers into the car.

The majority of car speakers are a standard size unless you go for something very custom. Below are some of the standard sizes for most car speakers:

  • Speakers that are six by nine inches give good sound quality, but without being loud in your ear. The size is reasonable and can fit with a plethora of vehicle designs and styles. They may be smaller than woofers and subwoofers, but they can still take up a large amount of space.
  • Speakers that have a range that is five by seven offers a wide range of sound and clarity. This size is also good with fitting into a large variety of car models. The only bad thing about using these types of speakers is that they have specific ports and they will not work with the wrong adaptation when installing into an audio system.
  • Six-point five-inch speakers are your basic models that you place inside of a car audio system. This is the norm that is found in most vehicles and such is the standard for speakers in a car. They offer a wide variation in sound output and will adapt to most car systems because they are standard.
  • Woofers and subwoofers have a range from eight to fifteen inches and can display a variety of sounds and increase bass power with the size.
  • Tweeters are speakers with a size that ranges from 1 inch to 2 inches. They give good support to the other speakers when adapted to a sound system. Tweeters allow the sound system to balance itself.

Size and style play a large part when it comes to quality and sound in a car. The right sound system needs the right speakers in order to attain the best potential for listening pleasure. A sound system should run at its optimal efficiency by following these steps and making sure to know the correct information before installing.

Car Door Speaker Buying Guide

Knowing the right information can be a value when it comes to installing car door speakers. Knowing tips and tricks that can make the work easy is always beneficial and can reduce time and cost.

Frequency Range

The range of the frequency determines the sound quality and how it is directed. By adjusting the frequency of the speakers, you will be able to increase the effect of the sound. Tweeters function as a means of creating high directional high-frequency sounds and if they are aimed at the correct angle, they can produce a most dramatic effect.

Using crossovers allows for an even distribution of the frequencies between the woofer and the tweeter. Power isn’t wasted between the speakers because frequencies aren’t reproduced by units in the system that aren’t meant to handle those sounds.

The result is a cleaner audio system with high efficiency and quality sound. These crossovers also include bi-amping which allows for the system to have separate sound amplification for both woofer and tweeter. This type of design is used for high-performance systems when they are installed.

Power Handling

When we discuss variables such as, Power Handling, we are discussing the amount of power that a speaker can handle. Low powered systems don’t need speakers that will handle large amounts of electrical output.

On the other hand, systems with high amounts of power need speakers that can handle large amounts of power. The secret to Power Handling is the power handling for the maximum RMS and not the peak power. Real measurements look at the extended amounts of time that a speaker can handle power, not short intervals.

Type of Speaker – Full Range (Coaxial) or Component

When trying to decide what type of speaker will fit best into a car system, one will have to consider the possibilities of Full-range and Component speakers. Full-range speakers provide all of the elements of a speaker in one.

They have a woofer for the low-end ranged sounds and tweeters for the high-end ranged sounds giving the unit a full range of sound frequencies. Some designs also include additional sound add-ons such as midrange and super-tweeter.

Use Full-range speakers to replace the factory ones without having too much trouble or issues. Full-range speakers carry a wide variety of designs and types to accommodate all models of car audio systems. There is a wide variety of prices and power ranges to choose, allowing for greater versatility and they can fit into any budget.

Another type of speaker, called the Component speaker, is designed to give you superior sound. A component system uses separate woofers, tweeters, and external crossovers to create a dynamic audio system that offers better sound quality.

The units can be placed in many different types of locations to acquire a better sound experience. By using Component speakers, a person can find the most adequate potential for “imaging” the sound system in the car. These types of speakers are made out of better materials and can offer exceptional sound quality and detail.

When trying to decide what type of speaker is best for a system, it is best to consider the effects of impedance. Impedance means the amount of resistance electricity will have when sending it to the speaker.

Less resistance means more electrical signal will get through to the speaker. It is best to check the impedance range of a speaker when connecting it to an amplifier. Not all amplifiers are set to work with the same impedance when it comes to speakers. Review the material about the impedance on a specific speaker to see if it will match your system.

Speaker Sensitivity

The measurement of speaker sensitivity concentrates on the amount of sound a speaker can yield when power is applied to the unit. Low power systems are ranked at a level that is 15 watts RMS per channel or lower. These include many types of factory installed speakers that are in cars.

These types of speakers do well with high sensitivity rankings that range in 90 dB. If your system is high powered, such as 16 watts RMS or higher, then you are going to need speakers with a low sensitivity ranking. With the correct powered system, the sound quality will be quite excellent.

Speaker Material

The material that the speaker is made from also plays an important part in the quality of the sound. It will also determine the durability of that speaker as well. Woofer materials are stiff yet lightweight in nature and are made from a synthetic material like polypropylene. Speakers with woven fabrics or metal coated synthetics are also used and can do well with a wide variation in temperature and moisture.

Tweeter materials are soft like poly, silk, or textile blends which makes the sound more refined sending out a mellow sound. Surround materials on woofers allows for free movement of the cone giving a much deeper bass sound. The material that is used is rubber based and provides excellent longevity, quality, and performance. Less expensive Surround Materials include Foam and Cloth.

Connection and Cabling

Having the correct speakers, woofers, tweeters, and any other component won’t matter if the devices aren’t wired correctly. The flow of electricity throughout the unit must be even and balanced in order to avoid problems with the audio system.

Amplifiers function as a means to provide electrical pressure to a circuit. OHMS are used when measuring resistance against the electrical pressure of the audio system. Watts are used to check the range of how much power will be released. Voice coils are used to create the electrical resistance and perform the duties of the system.

Problems can happen when the amplifier provides more power to the system than needed because of incorrect impedance adjustments. This causes the amplifier to shut down because of overheating before burning out. Consider the range and output of the amplifier when attaching it to the system.

Also, consider the outcome of wiring options that will change the level of impedance because of the cross connection of multiple sub systems and voice coils. Use dual voice coils to increase wiring options when setting up an audio system. Use RMS ratings to determine the power output needed for the amplifier to attain adequate sound quality for the system.


The price of many of these speakers can have a varied range depending on what type of system you have installed or would like to install. The cost can be anywhere from hundred dollars to more than one thousand depending on the system. In the car speaker world, the saying “pay peanuts, get monkeys” is very much applicable.


Hopefully the detailed buying guide and car speaker recommendations will aid your buying decision in the correct way. Before you go straight into purchasing your new car speakers, you may want to be sure your double din head unit or single din head unit is able to support the speakers. Outputs at the back of many stereo systems are different and won’t allow for certain car speaker setups.

On top of this, your battery in your car may have an extra electrical draw from these speakers and you will want to ensure it is at its best.
