Frequently Asked Questions

Do I need professional skills to install this amplifier board?

Not at all. The illustration of each interface is clearly printed directly on the protective plate, making it highly intuitive to wire, install, and use even without complex instructions.

Why is there no sound when I plug in the AUX cable?

When using the AUX input mode, you must first confirm that the Bluetooth connection to this module has been disconnected. The board prioritizes Bluetooth, so disconnecting it will free up the audio channel for your wired AUX source.

Does the board overheat when running at full 200W capacity?

The module is specifically designed with comprehensive over-heat protection, premium copper DC connectors, and an integrated heat dissipation setup to safely handle high currents without dangerous temperature spikes during long-term use.
