What to do if there's no sound from Planet Audio Car Receiver with amplifiers attached?
- M
  Matthew RiceSep 6, 2025
  If there's no sound output when operating your Planet Audio Car Receiver with amplifiers or a power antenna attached, the power antenna lead might be shorted to ground, requiring excessive current, or there may be an issue with the remote on the amplifiers or power antenna. To resolve this: Turn off the unit, remove all wires attached to the power antenna lead, and check each wire for a possible short to ground using an ohm meter. Turn the unit back on and 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 relay to provide remote-on voltage (excessive current required).
