: Check that the housing enclosure is constructed from non-metallic materials (such as ABS plastic or acrylic). Ensure no structural metal plates shield the antenna zone.
: If using it with a powerful amp like the PAM8403, ensure the audio output from the PCB is correctly filtered to avoid "hiss" or ground loop noise, as discussed in Instructables' DIY Bluetooth speaker guides .
