Tips and Warnings. Related Articles. Article Summary. Author Info Last Updated: September 5, Part 1 of Selecting New Speakers. Look at the stereo system you are installing your new speakers on. Some systems are simple stereo audio systems that have limited wattage and two or four channels, so watt speakers, or adding 8 or more just won't make sense.
Trying to push too many speakers can, in fact, cause the quality of the audio to be diminished, or even damage the stereo. Check the dimensions of the existing speakers so minimum modifications will be needed to fit the new ones in. Speakers come in different shapes and sizes, so a planning to mount a replacement speaker, knowing if the original was a 6X9 inch oval rather than a 4 inch Consider quality. Speakers with composite or fabric cones are usually noticeably better than those with paper, and ceramic permanent magnet speakers will out-perform wound electromagnetic speakers at the same power level.
Select speakers with trim packages you like. You may find many different styles and colors of trim and covers in a similar price range, so it makes sense to pick the ones that look good, not just sound good. Look at the electronic characteristics of your speakers. Some have inline resistors to prevent static and crosstalk, some allow wiring in a series circuit configuration to allow 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 requirements of your new speakers as it will affect the wiring. High wattage speakers may not be able to perform with the factory wiring, and changing these to a larger size may mean considerable work, since factory wiring is concealed in hard to reach places. Gather your tools. As noted in the intro, there are thousands of possibilities available when it comes to after-market speakers.
Because of this, any single list of tools is likely to be insufficient for installing some speakers and redundant for others. The tools you'll need to how to wire speakers in a car your new speaker system will probably include most of the following, but are not necessarily limited to these:  X Research source A variety of what colors do pumpkins come in flathead, phillips head, etc.
Ensure that the speakers you've chosen fit your car. Many after-market speakers will fit into the spaces for the stock speakers, while others will require minor modifications, like the installation of a mounting bracket, the drilling of new screw holes, etc.
Be sure to take this into account when you buy your new speakers - the installation processes for differently-sized or shaped speakers can vary in difficultly. Note that many speaker retailers offer online tools for determining which of their products best "fit" your car. Prevent electrical damage by disconnecting your car's battery. As with nearly all types of electrical work, it's important to protect yourself and the electrical system before beginning.
Disconnecting the battery's negative terminal prevents the risk of injury from electric shock or damage to the car's electronics through short circuiting, so be sure to do so before tampering with any of the car's internal electronics. Defer to any instructions provided with your new speakers. Since there's so many different types of speakers available, it's nearly impossible to write a how-to guide that will perfectly cover all of them.
The instructions below are highly generalized and may not apply to every single set of speakers on the market. Whenever necessary, defer to the instructions included with your speakers, as these will be specifically suited to your unique product.
Part 2 of Take any panels or speaker grilles off. Nearly all speakers in the interior of a car will be covered with some sort of protective paneling or grill. Before the speaker can be modified or replaced, this barrier must be removed.
Pry the grill off with a suitable tool, like a flat head screwdriver, removing any bolts or screws that are holding it in place if necessary. The work you'll have to do to access your car's factory speakers will vary from car to car. In worst case scenarios, for example, you may need to remove seats, crawl into the trunk to access important bolts or wires, or even remove entire door panels to gain access to the speakers.
Remove the factory speaker. Note that the speaker is usually, but not always, attached to a wiring harness, so take care not to rip it out when removing it. If you think you'll need to re-install the how to fix holes in plaster walls speakers in the future for instance, if you sell the cardon't forget to save any screws that you remove!
Connect the new speaker to the car's electrical system. Usually, connecting your new speaker is a fairly simple matter of plugging your speaker's wiring harness into the car's wiring harness. However, if your car doesn't have this simple type of connection, you may need to connect your speaker with a soldered or crimped connection.
Make sure you match the polarity of the car and speaker's connections. 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 later to fix a problem. Re-connect the battery's negative terminal and turn on the car's radio or stereo. Listen for sound coming out of your new speaker or look for visible vibrations at high volumes.
If your speaker won't work, this means that how to wire speakers in a car is a problem with its electrical how to wire speakers in a car. Secure the new speaker. Once you're confident that your speaker works properly, secure it in its seat in the door or dash. If you're lucky, your new speaker will fit in the factory speaker's housing.
Refer to the instructions included with your speaker. Install and test any subwoofers. Subwoofers are responsible for the ultra-low, "booming" bass how to make an business plan that some car owners idolize. If your car came with factory subwoofers, installing new woofers can be as easy as seating them in the existing housing and connecting them to the car's wiring harness.
If your car didn't come with factory subwoofers, however, or you'd like to install additional ones, your task may be much harder. You may need expand your stock woofer's existing mounting holes or make significant modifications to the car to house large woofers.
For instance, many people who want to add multiple woofers to their car custom-install a panel in the trunk to house the woofers. Subwoofers often have fairly large power demands and complicated wiring schemes.
You may want to buy and install a separate amplifier wiring kit to simplify the process of wiring your subwoofers. If not, you may need to connect the woofer directly to the battery and the car's stereo and ground the woofer manually. Install and test any tweeters. As with woofers, tweeters, which produce high-pitch frequencies, can be easy or difficult to install based on the factory components of your car.
If your car came with tweeters, you may only need to install the new ones in the existing housing and connect them to the existing wiring harness.
If, however, there are no spaces to install the tweeters, you may need to make your own or expand existing ones, use a mounting bracket, etc. Luckily, tweeters are much smaller than woofers, so the adjustments you'll need to make will be minor in comparison.
As with woofers, if your car didn't already have any tweeters, you may need connect the tweeter directly to the battery and stereo and ground the tweeter to the car's body. Replace all panels and speaker grilles. When all the components of your new speaker system have been installed, tested, and securely mounted in the car, you may replace any speaker grills or panels that you had to remove to install the speakers.
Make sure you've kept any screws that you had to remove to take the grill or panel off so that you're able to re-secure them properly. Congratulations - your new speaker system is ready to use! Maybe the ground is not properly setup, thus making noise in the form of static sounds.

?·?How-to and tips for wiring car speakers to crossovers. In order to correctly wire speaker crossovers, you’ll want to do the following: Be sure to plan for having enough speaker wire on hand. Many speakers do come with speaker wire, but more often than not (1) it’s fairly short in length or (2) it’s not great quality. Rewiring your car's speakers can be necessary for a variety of reasons. In cars that are more than 10 years old, the insulation on the wiring can wear down, exposing the wires. This deterioration can often cause short circuits, possibly resulting in permanent .
Everyone wants to listen to loud music while driving. Most people like to listen to loud music, and most like to listen to low volume. It depends upon the people who drive their car to longer or shorter routes. People who drive to longer routes do not like to listen to loud music in their car. But when they get any knowledge regarding the sound system of their car, they try to achieve that quality and equipment in their car. You can install more speakers with good sound quality when you need a louder sound.
But there are specific ways for that. So, we are here to tell you how you can wire 6-speakers in a 4-channel audio head. You have to go through the following steps to wire your speakers with the audio head so that you can get better sound quality:. Step1: Take the audio head unit out of the dash. Step2: Locate all the currently installed wires. Step3: Select the location for your speakers Step4: Wire with a proper architecture Step5: Mount the speakers.
Step6: Test the speakers. People feel difficulty in the installation of more speakers when they only have a limited channel audio head. So, if you are here, that means you also want to install more speakers with a less powerful or less supporting channel audio head. People ask too many questions about how to connect more speakers in their car for better sound.
Well, there is always a solution to every problem. Some people might install an amplifier along with an audio head while some might install a more powerful audio head. Some cars come with a 4-channel audio head because these cars come with pre-installed door speakers who are four in number. The audio head is always compatible with the stock speakers that are installed in the car. When people install a more powerful speaker in the car more power is required.
There is a specific way to take out the audio head from the dash because every car has a similar but different type of fitting in the dash. So, you have to see the user manual for opening the dash of the car and taking the head unit out of it. You may have to use tools like a dash-opener and a screwdriver because the dash is always fixed with some adjustments and fittings. After opening the dash of your car, you need to open the screw of the audio head and take the audio head out of the dash.
If you already have speakers installed in your car, which most cars have, then you have to plug out the power wires of the speakers and create a new structure of wiring that we are going to tell you afterward. If you already have speakers installed, then you may have the wiring installed in your car. You must locate all the wires wherever they are and create a new wiring structure according to your requirements. What is your requirement? As you want to install 6-speakers to a 4-channel head unit, you must have a 4-channel audio head in your car.
There will always be a different case for every person to use this method to wire their speakers because some people might have two speakers in their car, and some might have four. So, we will explain the method as you are installing a new set of speakers in your car. To install the wiring in your car you have to take out the dashes on the sides of your car so that it is easy for you to work your way from there.
If you already have wiring for stock speakers, then you have to take them out of their location so that you can easily create a new wiring structure in your car. Before diving into installing the wiring for your speakers, you must see where you will install your speakers in your car. Well, there are not enough places to select if you have a simple car. Whereas, if you have an SUV, then you may have different choices for your selections. Most commonly, people try to install the speakers in the doors or the trunk of their car.
We will suggest you the best location for your speaker so that you do not have to compromise any of the space in your car, especially the trunk of your car. The best way to wire six speakers in your car is to wire them in the doors and above the trunk. You can wire four speakers inside the doors and two speakers behind the backseat of your car. So, you have to find or create a better enclosure for your speakers to mount perfectly.
Now, you must be wondering that how can you wire 6-speakers with a 4-channel audio head unit. You may have heard of the series and parallel connection of the speakers. We will give you a better solution for our problem with a parallel wiring of your speakers.
So, as the head unit is out of the dash of your car, there are 4-channel ports located at the back of the audio head unit. You cannot install 6-wires on it directly. So, you have to follow a specific type of wiring structure to power your 6-speakers properly. Keep in mind that you must not use speakers which require high power to function.
Always use 4-ohm or less than 4-ohm speakers. Connect the two wires to the positive terminal and two wires to the negative terminals of the channel ports behind the audio head unit. Now, the next step is to route these wires to the selected locations for the speakers. Route the 2-channel wires from the left side of your car, and 2-channels from the right side of your car.
As all the four channels are busy to power 4-speakers, here is what you need to do to wire two more speakers in your car. Now, you do not have any port in the head unit to install more 2-channel wires for two more speakers. You will follow the next step to power two speakers which are located at the back of your backseat. Connect the negative wire of the left speaker which you are installing above the trunk with the negative wire of one of the speakers installed in the left doors. Connect the positive wire of the left speaker to the positive wire of the other speaker installed in one of the left doors.
So, one of the extra speakers is powered now. What you have to do next is, you have to connect the negative wire of the right speaker,which you are installing above the trunk with the negative wire of one of the speakers installed in the right doors. Connect the positive wire of the right speaker with the positive wire of the other speaker.
In this way, the wiring of two extra speakers can be done if you have a 4-channel head unit. When the wiring is done, you have to mount all the speakers inside their enclosures. In this way, the wiring will not be exposed and the speakers will be fitted properly.
You must use the required nuts and bolts or screws to mount all the 6-speakers in your car. The speakers that are to be installed above the trunk will have a wooden sheet on which the speakers will be mounted with screws. The speakers that are to be installed in the doors may cause some problems.
If your car does not have a factory fitting for the speakers, then you have to get a custom-built enclosure or fitting for your doors to mount the speakers in them. Door speakers will also require nut-bolts or screws to mount properly in the doors. The last and very important step in wiring your speaker is to test your speakers. You can test the speakers by turning the audio head unit on and playing some music on it.
Play the music loud to check the efficiency of the head unit of your car. The head unit can work fine with the present structure of wiring. Whereas,the proposed structure does not put heavy load on the head unit. It will only draw a little amount of power from the other speakers. So, you will not have to upgrade the head unit of your car. If you have any questions, just post in the comment, I keep adding answers to these questions in my daily blog.
