Understanding Your 2017 Honda Accord Speaker Size: The Basics

Before you even think about buying new speakers, you need to know what you’re working with. Getting the correct 2017 Honda Accord speaker size is crucial for a smooth installation and optimal sound performance. Honda typically uses standard sizes, which makes finding aftermarket replacements relatively easy.

Front Door Speakers

The front doors are usually where you’ll find the primary mid-range and bass drivers for your front soundstage. For most 2017 Honda Accord models, including the sedan and coupe, the front door speakers are:

6-3/4 inches (or 6.75 inches): This is the most common size you’ll encounter.
Many aftermarket 6.5-inch speakers will fit, often with a simple adapter bracket.

It’s important to check the mounting depth and cutout diameter for any specific speaker you’re considering. Some premium aftermarket speakers might be deeper than stock, requiring spacers or minor modifications.

Rear Door Speakers (Sedan Models)

If you have a 2017 Accord sedan, you’ll also have speakers in the rear doors. These typically match the front door size:

6-3/4 inches (or 6.75 inches): Again, 6.5-inch aftermarket speakers are generally a good fit with adapters.

Coupe models generally do not have rear door speakers, opting instead for speakers in the rear deck or side panels.

Rear Deck Speakers (Sedan Models)

For 2017 Accord sedans, the rear deck speakers play a significant role in filling out the sound for rear passengers and providing additional bass. These are usually:

6×9 inches: This oval shape is common for larger bass drivers or full-range speakers in the rear.

Replacing these can dramatically improve your bass response, especially if you’re not planning on adding a dedicated subwoofer right away.

Dash Tweeters

Located in the corners of your dashboard, near the windshield, are the tweeters. These tiny speakers handle the high frequencies, responsible for crisp vocals and bright instruments. They are typically:

1-inch to 1.5-inch: These are small, component-style tweeters.

Upgrading these often involves component speaker sets, where the tweeter comes with a matching mid-range speaker and a crossover network. This is a fantastic way to improve sound clarity and imaging.

Why Upgrade Your 2017 Accord Speakers? Benefits Beyond Better Bass

So, you know the sizes. But why bother with the hassle of an upgrade? The benefits of 2017 Honda Accord speaker size upgrades extend far beyond just turning up the volume. It’s about a complete transformation of your driving experience.

Here’s what you stand to gain:

Superior Sound Quality: Stock speakers are often made with inexpensive materials like paper cones. Aftermarket speakers use advanced materials (polypropylene, silk, titanium) that reproduce sound with far greater accuracy, clarity, and detail.
Enhanced Bass Response: While you might not get subwoofer-level bass, quality aftermarket speakers, especially those in the 6×9-inch range, offer much deeper and tighter bass than factory units.
Crisper Highs and Mids: Say goodbye to muddy vocals and piercing highs. New tweeters and mid-range drivers will bring out the subtleties in your music, from shimmering cymbals to clear guitar riffs.
Improved Power Handling: If you plan to add an aftermarket amplifier, better speakers are a must. They can handle more power without distorting, allowing you to play your music louder and cleaner.
Long-Term Durability: Many factory speakers degrade over time, especially in harsh car environments. Quality aftermarket options are built to last, offering a more sustainable 2017 Honda Accord speaker size solution that won’t need replacing again soon.
Personalized Soundstage: With component sets and careful tuning, you can create a more immersive and lifelike soundstage that feels like the artists are performing right in front of you.

Think of it as upgrading from a small, tinny radio to a full-fledged concert hall experience right inside your Accord.

Choosing the Right Speakers: A 2017 Honda Accord Speaker Size Guide for Every Budget

Navigating the world of aftermarket speakers can be overwhelming. This 2017 Honda Accord speaker size guide will help you make informed decisions, ensuring you get the best bang for your buck and a sound that truly satisfies.

Types of Speakers

Full-Range (Coaxial) Speakers: These are the simplest and most common. They combine all the speaker elements (woofer, tweeter, and sometimes a mid-range) into one unit. They are easy to install and a great upgrade from factory speakers.
Component Speakers: These sets separate the woofer, tweeter, and often a mid-range driver, connecting them via an external crossover network. They offer superior sound quality and imaging because you can position the tweeters independently for optimal sound direction. They are more complex to install but highly recommended for audiophiles.

Key Speaker Specifications to Consider

RMS Power Handling: This is the continuous power a speaker can handle. Match this closely with the RMS output of your head unit or amplifier. Don’t confuse it with “Peak Power,” which is a maximum burst it can handle.
Sensitivity: Measured in decibels (dB), sensitivity indicates how efficiently a speaker converts power into sound. Higher sensitivity (e.g., 90dB+) means the speaker will play louder with less power, which is great if you’re sticking with your factory head unit.
Impedance: Most car speakers are 4 ohms. Ensure your new speakers match your head unit or amplifier’s impedance for optimal performance and to prevent damage.
Frequency Response: This tells you the range of frequencies the speaker can reproduce. A wider range (e.g., 20 Hz – 20,000 Hz) means it can play both deep bass and high treble notes.
Cone Material: Look for durable, lightweight materials like polypropylene, woven fiberglass, or carbon fiber for woofers, and silk, textile, or aluminum for tweeters. These materials contribute to better sound reproduction and speaker longevity.

Matching Speakers to Your System

Consider your current setup. Are you keeping the factory head unit? If so, look for high-sensitivity speakers. If you’re adding an aftermarket amplifier, you can choose speakers with lower sensitivity and higher RMS power handling. For eco-friendly 2017 Honda Accord speaker size choices, consider brands known for using recycled materials or energy-efficient designs.

Step-by-Step Installation: Your DIY Guide to Replacing 2017 Honda Accord Speakers

Now for the fun part! This step-by-step guide will walk you through replacing your 2017 Honda Accord speakers, ensuring you follow 2017 Honda Accord speaker size best practices for a clean and professional-looking install.

Note: This guide focuses on door speaker replacement, as it’s the most common. Rear deck replacement follows similar principles for panel removal.

1. Disconnect the Battery

Open your hood and use a 10mm wrench to loosen the nut on the negative (-) terminal of your car battery.
Remove the cable and tuck it away from the battery post to prevent accidental contact.

2. Remove Door Panels

Locate Screws: Typically, there are screws behind the door handle, in the armrest cubby, and sometimes along the bottom edge of the door. Gently pry open plastic covers to expose them.
Remove Trim Pieces: Use your plastic pry tools to carefully remove any trim pieces (e.g., around the door handle, window switch panel). Disconnect any electrical connectors attached to these panels (e.g., window switches).
Pop Clips: Once screws are removed, use your pry tool to gently work around the perimeter of the door panel, popping out the plastic clips that hold it to the door frame.
Lift and Detach: Lift the door panel straight up and off the door. Be careful of any remaining wiring harnesses (e.g., for door lock actuators, courtesy lights). Disconnect these and set the door panel aside in a safe place.

3. Remove Old Speakers

You’ll see the factory speaker mounted to the door frame, usually held by 3-4 screws.
Unscrew the old speaker.
Disconnect the factory wiring harness from the back of the speaker.
Carefully remove the speaker from the door.

4. Prepare for New Speaker Installation

Clean Area: Clean any dust or debris from the speaker opening.
Install Sound Deadening (Optional): If using, cut and apply sound deadening material to the metal of the inner door skin around the speaker opening and inside the outer door skin. This dramatically reduces rattles and improves bass.
Mount Adapter Bracket: If your new speakers require adapter brackets, mount them to the door frame using the factory screw holes.
Attach Wiring Harness: Connect your new speaker wiring harness adapter to the factory wiring connector. Then, connect the other end of the harness to your new speaker terminals (positive to positive, negative to negative).

5. Install New Speakers

Carefully place the new speaker (or speaker/bracket assembly) into the opening.
Line up the screw holes.
Secure the speaker with screws. Do not overtighten, as you can strip the plastic bracket or damage the speaker frame.
Apply butyl rope or a foam speaker gasket around the speaker’s edge to seal it to the door panel, preventing air leaks and improving bass response.

6. Test the Speakers

Before reassembling the door panel, temporarily reconnect the battery.
Turn on your car’s stereo and test the new speakers. Check for sound, clarity, and ensure both left and right sides are working.
If everything sounds good, disconnect the battery again.

7. Reassemble Door Panels

Reconnect any electrical harnesses to the door panel itself.
Carefully align the door panel’s clips with the holes in the door frame.
Press firmly around the perimeter of the door panel until all clips snap back into place.
Reinstall all screws and trim pieces you removed in step 2.

8. Final Battery Reconnection

Reconnect the negative terminal of your car battery.
Test your stereo again, and enjoy your new sound!

Troubleshooting & Common Problems with 2017 Honda Accord Speaker Upgrades

Even with the best preparation, sometimes things don’t go perfectly. Here are some common problems with 2017 Honda Accord speaker upgrades and how to troubleshoot them.

No Sound from New Speakers:
- Check Connections: Ensure all wiring harness adapters are securely plugged in, and speaker wires are firmly attached to the speaker terminals (positive to positive, negative to negative).
- Fuses: Check your car’s audio fuse (refer to your owner’s manual for location).
- Head Unit Settings: Ensure the balance and fader settings on your head unit are centered.
- Speaker Polarity: If one speaker sounds “off” or weak, you might have reversed the polarity (+/-). Double-check the wiring.
Distortion or Buzzing:
- Loose Connections: Recheck all wiring connections for tightness.
- Overpowering Speakers: If you have an aftermarket amplifier, ensure its gain settings aren’t too high for your speakers’ RMS rating.
- Rattles: This is a common issue. Check if the speaker is securely mounted. Apply more sound deadening or butyl rope around the speaker frame and any loose wires inside the door. Ensure the door panel clips are all fully seated.
- Ground Loop Noise: A persistent hum or whine that changes with engine RPM often indicates a ground loop. Ensure all components are properly grounded to a clean, bare metal surface. This is a situation where calling a professional might be best.
Poor Bass Response:
- Air Leaks: Ensure the speaker is properly sealed to the door opening. Any air leaks will significantly reduce bass. Use butyl rope or foam gaskets.
- Speaker Polarity: Incorrect polarity can cause bass cancellation.
- Head Unit Settings: Check bass boost or equalizer settings on your stereo.
- Speaker Quality: Some speakers simply aren’t designed for heavy bass. Consider adding a small powered subwoofer if you crave more thump.
Factory Radio Not Working After Battery Disconnect:
- Some Honda Accord models require a radio security code to be re-entered after the battery has been disconnected. Check your owner’s manual or glove compartment for a sticker with this code. If you don’t have it, a Honda dealer can often provide it with your VIN.

If you’ve tried these steps and are still facing issues, don’t hesitate to consult a local car audio specialist. Sometimes, a professional eye can quickly diagnose a tricky problem.

Maintaining Your New Sound System: 2017 Honda Accord Speaker Care Guide

You’ve invested time and effort into upgrading your 2017 Accord’s audio. Now, let’s make sure it lasts! Following a few simple 2017 Honda Accord speaker size care guide tips will keep your system sounding great for years to come.
