Where is the rear door tweeter installed?

Rear door tweeters can be installed on the upper part of the door panel or on the A-pillar. Function of the horn: The horn is the audio signal device of a car. During driving, the driver can emit necessary audio signals as required and regulated to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used for urging movement and transmitting signals. Working principle of the horn: An automotive electric horn produces sound through the vibration of a metal diaphragm. When the horn button is pressed, current flows through the contacts to the coil, generating a magnetic force that pulls the armature down, forcing the diaphragm to move. The movement of the armature causes the contacts to open, interrupting the current and causing the coil's magnetic force to disappear. The diaphragm, along with the armature, returns to its original position due to its own elasticity and the spring plate, closing the contacts again and restoring the circuit. Current then flows through the contacts to the coil, generating magnetic force and repeating the above process. This cycle repeats continuously, causing the diaphragm to vibrate and produce sound.

Last time when helping a friend upgrade the car audio system, I specifically researched the installation position for rear door tweeters. Generally, they're mounted either at the reserved spot on the top edge of the rear door trim panel or near the triangular window. For my own installation, I deliberately chose adjustable-angle brackets to aim the tweeters directly at passengers' ears. It's crucial to properly install the waterproof sealing gasket - a fellow car enthusiast once burned out his units during rain because this was neglected. Wiring must avoid the window regulator tracks, and it's best to wrap the harness with felt tape to prevent rattling noises. Installation depth requires precise measurement; protruding too much risks head impact, while excessive recessing affects soundstage. Always remember to adjust phase after installation, otherwise the sound will lack focus.

The modification shop technician demonstrated the standard procedure when installing rear door tweeters for me. There are typically three installation methods for rear door tweeters: the most common is flush-mounted installation by cutting a hole in the upper door panel; the second is custom molding in the door handle triangle area; some vehicles allow direct replacement of the factory grille position. Key reminder: installation angle must be tested - the tweeter must be oriented toward passenger head height. During our installation, we used a laser positioning device to find the optimal projection point for coherent sound staging. Internal door panel wiring must avoid collision beams and power window motors, with wire harnesses sleeved to prevent abrasion.
