Radio​ has power but no sound

ronaldorutola, You did not give us much to go on here. So my guess is there may be a separate amp from the radio and it may have a bad fuse or is faulty or built in amp faulty, speaker wire harness plug may have come loose. More info. like year,make,model,factory radio/aftermarket and its make,model# and any other info. that may help diagnose the issue could help in tracing the problem. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
