What size are the rear door speakers?

The size of the rear door speakers in a vehicle can vary, but a common size is 6.5 inches or 6x9 inches. These dimensions provide a balance between sound quality, speaker performance, and available space within the door panel.


Understanding Rear Door Speaker Sizes


The size of the rear door speakers is an important consideration when designing or upgrading a vehicle's audio system. Rear door speakers are typically larger than front door speakers, as they have more available space within the door panel. Common rear door speaker sizes include:



  • 6.5 inches: A popular and widely-used size that offers good sound quality and bass response in a compact package.

  • 6x9 inches: A larger oval-shaped speaker that can provide more powerful sound and deeper bass, though it may require more installation space.

  • 5.25 inches: A smaller option that can work in tighter spaces, but may sacrifice some sound quality and volume compared to larger sizes.


The optimal size for your rear door speakers will depend on factors such as the available space in your vehicle, your audio system requirements, and personal preferences. It's important to measure the existing openings in your door panels to ensure a proper fit when upgrading or replacing speakers.


Factors to Consider


When selecting rear door speakers, there are several factors to consider beyond just the physical size:



  • Power handling: Ensure the speakers can handle the power output of your vehicle's audio system to avoid damage or distortion.

  • Frequency response: Look for speakers with a wide frequency range to reproduce the full spectrum of sound.

  • Sensitivity: Higher sensitivity speakers will require less power to achieve the desired volume, which can be beneficial for older or less powerful audio systems.

  • Mounting depth: Measure the available depth in your door panels to ensure the speakers will fit properly.


By considering these factors, you can select the best rear door speakers for your vehicle and enjoy an enhanced audio experience.
