I do believe the radio and TV use the same speaker. I think there is a switch tied in to the TV power switch. Originally, one leg of the radio cord went to the switch and the other to the power supply. Note: The radio is hot chassis, so you will need to rewire the switch so one leg goes to the chassis and the other to the switch (disconnect and discard the wire going from the switch to chassis). I will look up your model and have better info in the next couple of days.
