The speaker systems that come with many new cars are often of poor quality. Fortunately, aftermarket amps are not only a relatively inexpensive way to enhance your car’s audio capabilities, but they’re also generally easy to install (some amps are more difficult to use than others because of the large number of amps available).  see step 1 below for information on how to install a new speaker set in your car trunk.

Car Door Speakers

Part 1

  1. Look at the stereo with the new speakers installed. Some systems are simple low-power stereos with 2 or 4 channels, so adding more than 100 watts or 8 speakers doesn’t make sense. Attempting to overheat the speakers may affect sound quality or damage the stereo.
  1. If you are tuning a new amp, check the dimensions of your old amp. Speakers come in a variety of shapes and sizes. So, if you’re planning on setting up a different Twitter, knowing that the original Ellipse version is "6" and not "4" can give you more options. appropriate.
  1. Think of a high-quality synthetic or cross-diaphragm amplifier as generally much better than a paper amplifier. Ceramic permanent magnet amplifiers are superior to spiral electromagnetic speakers of the same output.
  1. Choose a custom speaker. You can find veneers and veneers in a variety of styles and colors at the same price point, so it’s a good idea to choose a veneer that looks good and looks good.
  1. Pay attention to the electronic characteristics of the amplifier. Some have internal resistors to prevent interference and interference, while others connect cables in a sequential circuit configuration, allowing you to add amplifiers or amplifiers as needed. Others connect the terminals to maintain the correct system impedance.
  1. 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.

Preparing to Install New Speakers


  1. Collect yours. As mentioned at the outset, there are thousands of speaker options on the market. Therefore, the list of devices may not be sufficient to configure some amplifiers and may be redundant for others. Tools needed to set up a new speaker system include, but are not necessarily limited to:
  • A variety of screwdrivers (flathead, phillips head, etc.)
  • Wire cutters/strippers
  • Crimping tool
  • Allen wrenches
  • Socket wrenches
  • Hobby knife
  • Soldering iron (and solder)
  • Electric drill
  • File
  • Torx driver
  • “Panel popper” tool
  • Electrical tape
  1. Make sure the speaker you choose is suitable for your vehicle. Many aftermarket amplifiers are built into the amplifier housing, but others require fine adjustments such as mounting brackets and drilling new screw holes. Keep this in mind when buying new speakers. Different speaker sizes and shapes may have different configurations. Many retail speaker dealerships that are difficult to replace have online tools to help you decide which one is best for your vehicle.
  1. Remove the car battery to avoid power outage. As with almost any electrical work, it is important to protect yourself and your electrical system before starting work. There is no risk of electric shock by removing the battery negative pole, and there is no damage to the vehicle electronics due to a short circuit. Do this before touching the vehicle’s internal electronics.
  1. Follow the instructions that came with your new speaker. With so many different types of headphones, it’s almost impossible to write them all by hand. The following steps are very general and may not apply to all amp kits on the market. If necessary, follow the instructions provided with the amplifier. Amplifiers are unique to the product.

Part 2


  1. Remove the speaker trim or grille. Almost all car speakers are covered with some sort of protective glass or windshield. This pick must be removed before replacing or replacing the speaker. Remove the grill using a suitable tool such as a flat-blade screwdriver and remove the set screw. What you need to do to access your car factory speakers depends on your car. In the worst-case scenario, you have to remove the seat and return to the trunk to access critical screws and cables, or remove the door panel completely to access the speaker.
  1. Remove the factory amp. Amplifiers are usually, but not always, connected to a wire harness. Therefore, be careful not to tear it when removing it. You may need to loosen one or more small screws or sticky foam or glue holding the speaker in place. If you think you will need to reinstall the factory speakers later (eg. if you are selling a car), don’t forget to unscrew them!
  1. Connect the new speaker to the car’s electrical system. Installing a new speaker is usually very simple once you run the cables from the amplifier to the car wiring. However, if your car’s connections aren’t that simple, you may need to solder or connect an amplifier using a wave connection. Make sure the polarity of the car and amplifier connectors match. The positive pole of the amplifier is the larger of the two, usually indicated by or a small dot. Electrical tape can be a dangerous alternative to electrical connections, especially in dashboards, where temperature changes can weaken the tape and cause problems later.
  1. Try using headphones. Now that you’ve connected the amplifier, it’s important to try it out so you don’t waste time troubleshooting later. Reconnect the negative pole to the battery and turn on the car radio or stereo. If you hear sound from the new speaker or if there is a loud noise, check for vibration. If the amplifier does not work, there is a problem with the electrical connection.
  1. Install new speakers. After verifying that the amplifier is working properly, install it in place or on the dashboard. If you’re lucky, the new amp will fit in its original case. However, the amplifier may require the use of mounting brackets (usually with the speaker), new screw holes, and/or glue to hold the speakers in place. see the description of the amplifier.
  1. Install and test the subwoofer. Subwoofers are responsible for the very low bass that some car owners prefer. If your vehicle is equipped with a factory amplifier, installing a new amplifier is as easy as installing it in an existing box and connecting it to the vehicle wiring. If your car doesn’t have a subwoofer from the factory, or if you want to install an additional subwoofer, the task can be even more difficult. The vehicle may need to be significantly modified to expand the mounting holes on existing subwoofers or to accommodate larger subwoofers. For example, many people looking to add more speakers to their car install custom trims in their car trunks to accommodate the speakers. Subwoofers often require a lot of power and complex wiring systems. To simplify the amplifier wiring process, we recommend that you purchase and install the amplifier wiring separately. If not, you may need to connect the amplifier directly to the car battery and stereo and manually ground the amplifier.
  1. Install and test each speaker. High-frequency subwoofers can be easy or difficult to install, depending on the car parts. If your car has an amplifier, you will need to add a new amplifier to the existing box and connect it to the existing wiring. However, if you don’t have the space to install the speakers, you will have to build your own enclosure (e.g. if the existing enclosure isn’t enough, build an existing one and use the mounting brackets). Fortunately, woofers are much smaller than woofers, so the adjustments required are less than this. If your car doesn’t already have speakers, you’ll need to connect the amp directly to the battery and stereo, and connect the amp to the console.
  1. Replace all speaker panels and grills. Once all components of your new car speaker system are safely installed, tested, and installed, replace any windows or speaker trims that need to be removed to install the speakers. Place the screws that must be removed to properly reinstall the oven or stove. Congratulations. Your new speaker system is ready for use!



Can you install car speakers yourself? 

Ans: You can easily solve this problem by installing a new amplifier in your home. It takes time and some tools, but the entire car speaker replacement process is far from the most complex solution you can get.


How do I make my door speakers sound better? 

Ans: Here are 5 things you can do to improve the performance of your upgraded speakers.

  • Deactivation of the exterior door panel
  • Sealing of the interior door panel
  • Close the sound
  • absorbing laminate of the foam interior trim Mobile foam
  • each headphone washer


How do I get more bass out of my speakers? 

Ans: The larger the speaker housing relative to the speaker diameter, the deeper the bass reproduction. In other words, the smaller the speaker, the better the bass response. So, it is better to buy a bigger box.
