Toyota Avensis T270 Yaris P9 Rear Door Speaker Left Right N/O/S 861600D180

Toyota Avensis T270 Yaris P9 Rear Door Speaker Left Right is an original component from the Electronic control modules and controllers group, designed for operation in the vehicle's rear doors. It ensures stable audio signal reproduction within the factory sound system, maintaining the correct electrical and acoustic parameters specified by the manufacturer. This is a practical solution for users who want to restore proper sound system operation without interfering with the installation.

Purpose and vehicle placement

The presented speaker is intended for installation in the rear part of the bodywork, on the left or right side. This placement allows for maintaining an even sound distribution in the cabin, in accordance with the factory design of the Toyota audio system. The component works with the original wiring harness and factory door mounts, which facilitates installation and reduces the risk of incorrect connection.

Technical and functional characteristics

The speaker operates as a component of the vehicle's electrical system, controlled by systems from the Electronic control modules and controllers group. It has been designed to work with the factory radio or multimedia unit, ensuring it maintains the correct impedance, volume level, and sound consistency with the other transducers in the car. The properly selected basket and diaphragm construction promotes stable operation in conditions typical for doors – under varying temperatures, humidity, and vibrations. In practice, this means that after installation, there is no need for additional system configuration – the speaker works in plug-and-play mode with the factory installation. This is a beneficial solution for workshops and individual users who expect a predictable result without experimenting with replacements.

Benefits of using an original speaker

Using an original Toyota component allows for maintaining the consistency of the electrical and acoustic parameters of the entire sound system. Compared to random replacements, this reduces the risk of:

• distortion or excessively low volume levels in the rear doors,
• incorrect loading of the audio control unit's output path,
• the need for modifications to the installation or door mounts. For the user, this means predictable installation and maintaining a sound character close to the factory original. For the service center – shorter working time and lower risk of complaints related to incompatibility.

Condition, verification, and practical application

The item is offered as a used original component, which allows for combining reasonable cost with maintaining proper fitment for the Toyota installation. Before installation, it is recommended to perform a standard check of electrical connections and the correctness of the mounting in the door to avoid unwanted resonances and acoustic interference. This type of speaker will prove useful both when replacing a damaged transducer and when restoring full functionality of the audio system after body and paint repairs of the rear doors. If you are planning a comprehensive repair or modernization of the electronic installation area in your Toyota car and need other elements from the same group, such as controllers, modules, or actuators, check the available parts in the Toyota electronic control modules and controllers category.

More about choosing used electronics

When selecting used electrical installation elements – including speakers working with control modules – it is worth knowing the basic principles of assessing their suitability and safety of use.
