What to do if Planet Audio P9630B Car Receiver has no sound output with amplifiers?
- PparrishdanielleSep 13, 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 may be shorted to ground, or excessive current is required by the amplifiers or power antenna. Here's what to do: 1. Turn off the unit. 2. Remove all wires attached to the power antenna lead, and check each wire for a possible short 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).
