In most cases, the rear speakers for a 2007 Honda Accord are 6.5 inches in diameter (about 165 millimeters). This is the standard size that fits the rear doors of most trims from that year.
Understanding the size matters because the rear speakers are a common upgrade target for improving midrange clarity and overall sound balance. The exact fit can vary by body style (sedan vs. coupe), trim level, and whether you’re replacing in the rear doors or in the rear deck. The guide below outlines the typical size and practical considerations to help you pick the right speaker for your car.
Standard rear speaker size for a 2007 Accord
Here is the typical size you should expect when shopping for replacement rear speakers for a 2007 Accord.
- 6.5-inch (165 mm) rear door speakers, commonly 2-way coaxial design, with a 4-ohm impedance.
Note: Some very early or unusual factory setups could differ slightly, but 6.5" rear door speakers are the standard across most 2007 Accords, whether sedan or coupe.
What to check before buying replacements
Before you purchase new speakers, verify a few measurements and compatibility factors to ensure a clean, hassle-free install.
- Diameter and mounting: 6.5 inches (165 mm) is the standard size for the 2007 Accord’s rear doors; confirm your model’s exact measurement if you’re unsure.
- Mounting depth: Expect roughly 2.0–3.0 inches of mounting depth; deeper speakers may require spacers or trimming to clear window regulators or door panels.
- Impedance: Most aftermarket replacements are 4 ohms; keep 4-ohm speakers to match the factory head unit or consider a suitable amplifier if you’re upgrading sound power.
- Connectors and wiring: Honda typically uses a specific harness; you may need a harness adapter or plug-and-play connector to maintain a clean install.
- Rear deck options: If your car has any installed rear deck speakers or a nonstandard layout, measure those as well; some market-specific trims differ.
Concluding guidance: When in doubt, bring a tape measure and check the factory speaker dimensions printed on the existing speaker or consult the service manual for your exact 2007 Accord trim. This ensures you buy the right size and avoid fitment issues.
Summary
The standard back-speaker size for a 2007 Honda Accord is 6.5 inches (165 mm) in the rear doors. Before buying replacements, confirm diameter, mounting depth, impedance (4-ohms is typical), and connector compatibility to ensure a smooth upgrade. With proper checks, a 6.5" aftermarket speaker can deliver improved midrange and overall sound quality without major fabrication.
