Hi I am new to this forum I am looking for help I have Hook a amp and a sub in my truck but I can not get the radio to turn on the subwoofer on the radio and advise
Did you hook up the amp turn on wire off the deck? Are you getting voltage on the amp turn on wire when the deck powers up? Are you sure you have voltage on the battery cable? Check for good ground.
These are just some basic starting points for troubleshooting. I could give you some more tips if you provide a bit more information about the system and what you've done for troubleshooting so far.
