1999 Honda Accord Speaker Size: Ultimate Guide for Perfect Fit
The 1999 Honda Accord is a popular car for many reasons. It’s reliable, easy to maintain, and offers a comfortable ride. But one area where owners often want to upgrade is the audio system. If you’re thinking about changing the speakers in your Accord, knowing the speaker size is essential. This information helps you buy the right speakers, avoid installation problems, and enjoy better sound quality. In this article, you’ll learn exactly what speaker sizes fit your 1999 Honda Accord, how to replace them, and what matters for a good upgrade. You’ll also get practical tips, data, and answers to common questions.
Speaker Sizes In The 1999 Honda Accord
Finding the right speaker size for your car is the first step before buying new speakers. The 1999 Honda Accord comes in sedan and coupe models, and the speaker sizes are almost the same for both.
- Front door speakers: 6.5 inches (round)
- Rear deck speakers: 6×9 inches (oval)
- Tweeters (some models): 1 inch
These sizes are standard for the 1999 Honda Accord, but it’s always a good idea to check your specific car model before buying. Sometimes, trim levels or aftermarket changes can affect the speaker fit.
Why Speaker Size Matters
- Proper fit: If a speaker is too big or small, it won’t fit or may sound bad.
- Sound quality: Right size speakers produce clearer audio.
- Easy installation: Matching the size saves time and effort.
Many beginners overlook the importance of speaker depth. The mounting depth is how thick the speaker is, and it affects whether the door panel will close properly after installation.
Replacing Front Door Speakers
The front doors of the 1999 Honda Accord use 6.5-inch speakers. These are the most common size for car doors, making it easy to find replacements.
Steps For Replacement
- Remove the door panel: Use a screwdriver to take off screws and clips.
- Disconnect the old speaker: Unplug the wiring harness.
- Check the mounting depth: Most 6.5-inch speakers fit, but if the speaker is too deep, it may hit the window track.
- Install the new speaker: Use the original screws or brackets.
- Test sound: Before closing the door panel, play music to check for vibrations.
Practical Example
Suppose you buy a JBL 6.5-inch speaker. Its mounting depth is 2.1 inches, which fits most Accords. But if you buy a speaker with 2.8-inch depth, it may not fit unless you modify the door.

Rear Deck Speakers
The rear deck uses 6×9-inch oval speakers. These speakers handle more bass and power, giving your music a fuller sound.
Replacing Rear Speakers
- Access the rear deck: Usually, you need to remove the rear seat and deck cover.
- Unscrew the old speakers: Use a Phillips screwdriver.
- Check speaker depth: The space under the deck is limited.
- Install new speakers: Align the holes and screw in.
- Connect wires: Match positive and negative terminals.
Data Table: Rear Speaker Specs
Here’s a quick comparison of common 6×9-inch speakers:
| Brand | Size | Mounting Depth | Power Handling |
|---|---|---|---|
| Pioneer | 6×9″ | 2.8″ | 80W RMS |
| Kenwood | 6×9″ | 3.0″ | 100W RMS |
| JBL | 6×9″ | 3.1″ | 90W RMS |
Choose a speaker that fits your deck depth (less than 3. 1 inches is safest).
Tweeters In Some Models
Some 1999 Accords have 1-inch tweeters. Tweeters improve high-frequency sounds (like cymbals and vocals). If your car has them, they are usually mounted on the dashboard or door.
Installing Tweeters
- Surface mount: Use adhesive or screws.
- Flush mount: Cut a hole for the tweeter.
- Wire connection: Tweeters often need a crossover (small filter) to work well.
If you don’t have factory tweeters, you can add them. Just make sure your new speakers include a crossover, or buy one separately.
Speaker Wiring And Connectors
Speaker installation also involves wiring. The 1999 Accord uses simple wiring, but getting the polarity correct is important.
- Positive wire: Usually white or gray.
- Negative wire: Usually black or green.
- Harness adapters: Let you plug new speakers without cutting wires.
Common Mistake
Many beginners connect the wires backward. This causes weak bass or strange sound. Always check wire color and test before finishing the install.
Choosing The Right Replacement Speakers
When choosing new speakers for your Accord, there are several things to consider besides size.
Key Factors
- Power handling: Speakers should match your car’s stereo power.
- Sensitivity: Higher sensitivity means louder sound with less power.
- Material: Look for durable cones (polypropylene, rubber surrounds).
- Brand reputation: Trusted brands offer better warranties and quality.
Comparison Table: Speaker Features
Here’s how different features compare:
| Feature | Basic Speakers | Premium Speakers |
|---|---|---|
| Power Handling | 30-50W | 80-120W |
| Sensitivity | 85-88 dB | 90-94 dB |
| Material | Paper Cone | Polypropylene |
| Warranty | 1 year | 2-5 years |
Installation Tips For Beginners
Installing car speakers is not difficult, but there are some tips that make the process easier and safer.
- Use panel tools: Plastic tools avoid damaging the door.
- Keep screws organized: Place screws in a cup to avoid losing them.
- Check fit before wiring: Put the speaker in the hole to see if it fits.
- Seal gaps: Use foam tape to prevent vibrations.
- Test before finishing: Always play music before closing panels.
Non-obvious Insight
Many beginners skip sound deadening. Adding a thin foam or mat inside the door can reduce vibration and improve sound. This is a cheap upgrade that makes a big difference.
Common Problems And Solutions
Even with the right speaker size, you may face some issues.
- Speaker doesn’t fit: Check depth and diameter, trim plastic if needed.
- No sound: Check wiring and fuses.
- Poor bass: Check speaker polarity and quality.
- Rattling noises: Tighten all screws and add foam tape.
Example
A user installs a 6. 5-inch speaker but hears rattling. After adding foam tape around the speaker, the noise stops and sound improves.
Upgrading The Audio System
If you want even better sound, consider upgrading other parts.
- Head unit: Modern radios improve sound and power.
- Amplifier: Adds more power for stronger bass and clarity.
- Subwoofer: For deeper bass, add a small sub in the trunk.
Always match the speaker size and power to your upgrades. Too much power can damage speakers.
