Technical Application: How it works with Speakers
The BTS766 acts as a High-Side Switch.
Placement: It sits between the car's battery (12V) and the speaker amplifier/output.
Function: When the radio turns on, it sends a small signal to the BTS766's input pin. The BTS766 then opens the "gate," allowing high current to flow to the speakers.
Issue: Audio is Distorted or Crackling
Source Check: Ensure the volume on your phone is at 80-90%, not 100%. If the source volume is maxed out, digital clipping occurs before it hits the speaker.
Debris: If used outdoors, check the passive radiators (the vibrating plates on the sides) for dirt or magnetic debris.
