How to fix no sound from Power Acoustik PDN-721HB with amplifiers?
- MMelissa TranAug 10, 2025
If there's no sound output from your Power Acoustik Touch Panel when using amplifiers or a power antenna, the power antenna lead might be shorted to ground, requiring excessive current, or there might be an issue with the remote on the amplifiers or power antenna. Here’s how to troubleshoot: 1. Turn off the unit. 2. Remove all wires attached to the power antenna lead and check each wire for shorts to ground using an ohm meter. 3. Turn on the unit. 4. Reconnect each amplifier remote wire to the power antenna lead one by one. If the amplifiers turn off before all wires are attached, use an external replay to provide remote-on voltage (excessive current required).
