Toyota Vellfire / Alphard Back Door Speaker – Second Hand Overview
This page provides general information about the second-hand back door speaker used in the Toyota Vellfire and Alphard (30 series). These speakers are mounted in the rear door and are an integral part of the vehicle’s factory audio system. If you are looking for a used replacement or upgrade, understanding the specifications and condition is essential.
Compatible Models
The 30-series Vellfire and Alphard (model code AH30) are the primary vehicles for this speaker. It is designed for the rear door position and may vary slightly depending on the audio package (standard or premium). Always verify the speaker size, impedance, and connector type before purchasing a used unit.

- Size: 6×9 inches or 6.5 inches (depending on trim)
- Impedance: 4 ohms

What to Check When Buying Second Hand
When purchasing a used back door speaker, inspect the following:
- Cone condition: Look for tears, punctures, or deformation.
- Surround: The foam or rubber edge should be intact without dry rot.
- Coil resistance: Use a multimeter to ensure the voice coil is not open or shorted (typical reading 3–4 ohms).
- Connector: Ensure the terminals are clean and not corroded.
- Mounting holes: Check for cracks or damage to the plastic frame.
A visual inspection alone may not reveal all issues; testing the speaker with a low-voltage audio source is recommended if possible.
Installation Notes
Replacing the rear door speaker on a Vellfire/Alphard typically requires removing the door panel. The speaker is secured with screws or rivets. If the used speaker does not come with a mounting adapter, you may need to reuse the original bracket. Ensure the speaker is wired with correct polarity to maintain sound phase.
