The rear speakers in a 2008 Honda Fit are 6.5 inches in diameter.
In the U.S. market and many other regions, the 2008 Fit uses 6.5-inch two‑way speakers in the rear doors as part of the standard audio setup. This is the common size you’ll encounter when replacing or upgrading the rear speakers. Impedance is typically 4 ohms, aligning with most aftermarket options, though it’s wise to verify exact specifications if your vehicle has a factory subwoofer or amplified system.
Model scope and rear speaker specs
Understanding where the rear speakers fit into the model range helps ensure you’re selecting the right replacement. For the 2008 Fit, the rear-door speakers are generally the same size across common trims, making a 6.5-inch replacement compatible in most cases.
Common configurations by market
Across many markets, the 2008 Honda Fit offered a standard four‑speaker system with 6.5‑inch rear door speakers. Some higher‑end audio setups could incorporate additional amplification or a subwoofer, but the rear-door diameter remained 6.5 inches in the typical configuration.
How to confirm the size in your car
Before purchasing replacements, verify the exact size and fitment for your vehicle. Here’s how to check without guessing.
- Carefully remove the rear door panel and inspect the speaker opening for diameter and mounting depth.
- Measure the speaker opening with a ruler or tape measure to confirm it’s 6.5 inches (approximately 165 mm).
- Inspect the existing speaker itself for any model numbers or specifications printed on the magnet or cone.
- Consult the vehicle’s service manual or Honda’s parts catalog for the exact OEM size and part number for your VIN.
In practice, if you have a standard 2008 Fit without a factory sub, you’re almost certainly looking at a 6.5-inch rear speaker. Confirming with your VIN and a manual helps avoid buying the wrong size.
Replacement options
When shopping for replacements, the most common and straightforward option is a 6.5-inch aftermarket speaker. Here are typical choices.
- 6.5-inch 2‑way coaxial speakers, which are plug‑and‑play in many setups
- 6.5-inch component sets, for upgraded audio with separate woofer and tweeter (may require more installation work)
- 4‑ohm impedance is standard for most aftermarket 6.5" speakers; verify your factory impedance to ensure compatibility
Some aftermarket kits may require mounting brackets, adapters, or modifications for proper fitment, especially if there is limited depth behind the door panel. Always check wiring harness compatibility and seek guidance if you’re unsure.
Practical installation tips
Impedance, connectors, and depth
Most 6.5-inch rear speakers are 4 ohms and use standard vehicle harness connectors, but adapter kits are sometimes needed to ensure a clean electrical connection and proper mounting. Check the depth of the speaker and compare it to the available cavity behind the door panel to avoid fitment issues.
Professional installation considerations
If you’re upgrading for a meaningful audio improvement, a professional installer can help with impedance matching, wiring upgrades, and appropriate mounting brackets to preserve door operation and sound quality.
Summary
For a 2008 Honda Fit, the rear speakers are typically 6.5 inches in diameter. Use this as the baseline when shopping for replacements, but verify via the door panel, VIN, or service manual to account for any market-specific or optional equipment that could alter the standard setup. With the right 6.5-inch speakers and proper installation, you can achieve a straightforward upgrade without major alterations.
