Why Replace Your Speakers?

Before we jump into the nitty-gritty of the replacement process, let's talk about why you might want to upgrade your speakers in the first place. The stock speakers that come with your 2019 Nissan Sentra, like many vehicles, are often designed to meet a price point rather than deliver premium sound quality. This means they might lack the clarity, depth, and overall performance that you crave. Replacing them is one of the most cost-effective ways to improve your car's audio system. Here are some compelling reasons to consider a speaker replacement:

Improved Sound Quality: New speakers will offer crisper highs, deeper bass, and a more balanced soundstage. You'll hear details in your music that you never noticed before.
Enhanced Clarity: You'll experience less distortion and greater clarity at higher volumes, making your music more enjoyable, whether you're listening to podcasts or your favorite rock anthems.
Increased Volume: Aftermarket speakers often handle more power than the factory ones, allowing you to crank up the volume without sacrificing sound quality.
Better Bass Response: If you're a bass enthusiast, upgrading your speakers, or adding a subwoofer, can provide a more powerful and satisfying low-end response. It can make all the difference in the world when you like a little extra thump in your music.
Durability: Factory speakers can degrade over time due to wear and tear. Replacing them with higher-quality speakers can improve the longevity of your audio system.

Ultimately, upgrading your speakers is about enhancing your overall listening experience. It's about enjoying your music the way it was meant to be heard. So, if you're ready to take your car audio to the next level, it's time to consider a speaker replacement! In the following sections, we will discuss how to choose the right speakers, what tools you need, and the step-by-step instructions for installation. This investment will surely pay off with every drive.

Choosing the Right Speakers

Choosing the right speakers for your 2019 Nissan Sentra is a crucial step in the replacement process. You'll want to take a few factors into consideration to ensure you get the best possible sound and fit. Here's a breakdown of what to look for:

Speaker Types

Coaxial Speakers: These are the most common and often the easiest to install. They have the tweeter and woofer mounted on the same axis, making them a good choice for a simple upgrade. They're generally a more budget-friendly option.
Component Speakers: These systems separate the tweeter and woofer, allowing for better sound imaging and a more refined sound. They usually come with external crossovers that help direct the correct frequencies to each speaker. They typically offer superior sound quality but require more complex installation.

Speaker Size and Fit

It's important to find speakers that fit directly into your 2019 Nissan Sentra's existing speaker locations. Check your vehicle's specifications or consult a car audio guide to determine the correct size for the front and rear speakers. You'll generally find that the front and rear speakers have different sizes. You can find this information by searching online for your vehicle's make, model, and year. You can also measure the speakers to be sure.

Front Speakers: Typically, the front speakers are 6.5 inches or may require adapters.
Rear Speakers: The rear speakers are usually 6.5 inches.

Power Handling

Make sure the speakers you choose can handle the power output of your car's head unit or any aftermarket amplifier you plan to use. If you have an amplifier, select speakers with a higher power-handling capacity. If you don't, you can select speakers with a lower power-handling capacity. If the speakers can't handle the power, they will blow. And if they have too much, you may not be maximizing the speakers' full potential.

Impedance

Most car speakers have an impedance of 4 ohms, which is compatible with most factory and aftermarket head units. Verify the impedance of your head unit before purchasing speakers.

Material

Consider the materials used in the speakers. The materials can impact the sound quality and durability.

Woofer Cones: Materials like polypropylene or treated paper offer a good balance of sound quality and durability.
Tweeters: Silk or other soft dome tweeters produce smooth highs, while hard dome tweeters (like metal) can offer more clarity.

Brand and Reviews

Research different speaker brands and read reviews to get an idea of the sound quality and reliability. Popular brands in the car audio world include Alpine, JBL, Kicker, and Rockford Fosgate, but many other great brands are out there too. Make sure the speaker matches your budget and your sound preference.

By taking these factors into account, you can select speakers that will significantly improve the sound quality in your 2019 Nissan Sentra.

Tools and Materials You'll Need

Before you start the speaker replacement process, gather the necessary tools and materials. Having everything ready beforehand will make the installation smoother and more efficient. Here's a list of what you'll need:

New Speakers: The stars of the show! Choose the speakers that fit your vehicle's specifications and sound preferences. Make sure you have the correct size for the front and rear locations.
Screwdrivers: You'll need a variety of screwdrivers, including Phillips head and flathead, to remove the door panels and old speakers. It's usually a good idea to have a set with different sizes and shapes to deal with all kinds of screws.
Panel Removal Tools: These plastic tools are designed to safely remove door panels without damaging them. Using these tools will prevent scratches or breaks.
Socket Wrench Set: You might need a socket wrench to remove any bolts securing the speakers or door panels.
Speaker Wire: You might need new speaker wire if the new speakers' terminals aren't compatible with your existing wiring. Choose the right gauge of wire (usually 16-18 gauge) for your speakers.
Wire Strippers/Crimpers: These tools are necessary to cut and strip the speaker wire and crimp connectors.
Wire Connectors: You can use crimp-on connectors, such as spade connectors or butt connectors, to connect the speaker wire to the speakers and your car's wiring harness.
Electrical Tape: To insulate wire connections and secure any loose wires.
Drill (Optional): If you need to make any adjustments or modifications during the installation, a drill might be helpful.
Work Light: A good work light will help you see what you're doing, especially in the darker areas of your car.
Owner's Manual: It's a good idea to consult your car's owner's manual for any specific instructions or diagrams related to speaker removal and installation.
Gloves (Optional): To keep your hands clean and protect them.
Safety Glasses: These are especially important if you are drilling, to keep any debris from getting in your eyes.

Having the right tools is the first step in a successful speaker replacement. Make sure everything is prepared, so you don't have to stop midway through the process to find something. It's also smart to have all your supplies together, so you don't lose anything.

Step-by-Step Installation Guide

Now, let's get into the nitty-gritty of the installation process. Follow these steps to replace your speakers in your 2019 Nissan Sentra:

Step 1: Prepare Your Vehicle

Park and Power Down: Park your car on a level surface and turn off the engine. Remove the key from the ignition.
Disconnect the Negative Battery Terminal: This is a crucial safety step to prevent electrical shocks or shorts during the installation. Use a wrench to loosen the nut on the negative battery terminal and disconnect the cable. Ensure the cable does not touch the terminal during the work.

Step 2: Remove the Door Panel

Locate and Remove Screws: Carefully inspect the door panel for screws. They are usually hidden behind plastic covers, in the door handle, or around the edges of the panel. Use a screwdriver to remove these screws. The panel removal tool will be helpful here.
Remove the Door Panel: Once you've removed all the screws, use your panel removal tool to gently pry the door panel away from the door. Start at one corner and work your way around the panel, releasing the clips that hold it in place. There can be a lot of them, so be patient and go slow. Be careful not to break the clips.
Disconnect Wiring: Once the panel is loose, you'll need to disconnect any wiring connected to the door panel, such as the power window and door lock switches. Unplug the connectors carefully.
Remove the Door Panel Completely: Once the wiring is disconnected, you can completely remove the door panel and set it aside in a safe place.

Step 3: Remove the Old Speakers

Locate the Speakers: The speakers are usually held in place by screws or rivets. Locate the screws or rivets that secure the speaker to the door.
Remove the Speakers: Unscrew or drill out the rivets to remove the old speakers. Be careful not to damage the surrounding door panel.
Disconnect the Wiring: Disconnect the wiring from the old speaker. You might need to cut the wires or use a connector.

Step 4: Install the New Speakers

Connect the Wiring: If your new speakers have different connectors, you may need to cut and strip the wires and use wire connectors to connect them to the car's wiring harness.
Mount the New Speakers: Align the new speaker with the mounting holes. Secure it using the screws or rivets provided with your new speakers or the ones you removed from the old speakers.
Test the Speakers: Before putting the door panel back on, connect the negative battery terminal and test the new speakers to make sure they're working correctly. Turn on your car's stereo and test the sound.

Step 5: Reassemble the Door Panel

Reconnect Wiring: Reconnect any wiring that you disconnected from the door panel, such as power window switches and door lock switches.
Reattach the Door Panel: Carefully align the door panel with the door and snap the clips back into place. Ensure the clips are properly aligned.
Secure the Panel: Screw the panel back into place, using the screws you removed earlier.
Reconnect the Negative Battery Terminal: Reconnect the negative battery terminal, and you're done!

Repeat these steps for the remaining speakers you plan to replace.

Pro Tips and Troubleshooting

Here are some pro tips and troubleshooting tips to make your speaker replacement go smoothly:

Take Photos: Before removing any components, take photos of the existing wiring and panel arrangement. These photos will serve as a visual guide during reassembly.
Label Wires: Labeling the wires before disconnecting them will help you remember which wire goes where, preventing confusion during reinstallation. The photos will help with this too!
Work in a Clean Area: Try to work in a clean, well-lit area to make the job easier and reduce the risk of losing small parts.
Be Patient: Don't rush the process. Take your time, and double-check your work to avoid mistakes.
Check Polarity: Make sure the positive and negative terminals of the speakers are connected correctly. Incorrect polarity can negatively affect sound quality.
If you get stuck: If you get stuck at any point, don't hesitate to consult online forums, YouTube videos, or car audio experts for assistance.
