For most 2003 Honda Accord models, the rear speakers are typically 5.25 inches in the rear doors, while the rear deck (parcel shelf) speakers are usually 6x9 inches. Exact sizes can vary by trim and body style, so it’s best to verify on your specific vehicle.
Where the back speakers are and their typical sizes
The Accord stores its back speakers in two common locations: the rear doors and the rear deck (parcel shelf). Below are the sizes you’ll most often encounter.
- Rear door speakers: commonly 5.25 inches (133 mm) in many 2003 Accord sedans and coupes.
- Rear deck (parcel shelf) speakers: commonly 6x9 inches (152 mm x 229 mm) on most sedans.
Note that some trims or aftermarket configurations may differ, and the coupe or sedan variant can influence exact mounting and size. If you’re replacing speakers, check the label on the current speakers or measure the openings to be sure.
How to confirm the exact size on your car
To confirm the precise sizes for your specific vehicle, use these steps.
- Inspect the current speakers: look for size markings on the speaker frame or magnet, or remove a speaker to read the size stamped on the frame.
- Measure the openings: use a tape measure to determine the diameter of the circle for the door speakers (approximately 5.25" or 6.5") and the dimensions of any rear deck speaker cutouts (often 6x9" for the deck).
- Consult reliable resources: check the owner's manual, a factory service manual, or retailer guides (such as Crutchfield) for the exact specs by year/model and body style.
Knowing the exact size helps ensure a proper fit, especially if you’re upgrading to aftermarket speakers or adding an amplifier.
Upgrade considerations
If you’re planning to upgrade the back speakers, keep the following in mind.
- Choose size-appropriate sets: 5.25" for rear doors, 6x9" for rear deck are common starting points, but verify for your model.
- Check enclosure and depth: some replacements require more mounting depth or spacers/brackets to fit behind panels or on the shelf.
- Match impedance and power: most aftermarket car speakers are 4 ohms; ensure your head unit or amplifier can supply compatible power without distortion.
With careful selection and proper mounting, you can improve rear-channel clarity and overall sound balance in your 2003 Accord.
Summary
In the 2003 Honda Accord, back speakers are typically 5.25 inches in the rear doors and 6x9 inches on the rear deck, though sizes can vary by trim and body style. Always verify the exact measurements on your car before purchasing replacements or upgrades, and consider enclosure depth and impedance to ensure a proper fit and sound performance.
