Now that the crisis is over you may want to consider picking up on of those WIRELESS BLUETOOTH portable speakers...
These work anywhere out on tables etc around your trailer setup... No Wires and sound great..
I got my first cheap one from WALMART but now notice that AMAZON has a whole line of different sizes and shapes on their pages...
Mine has a transmitter module you plug into the headphone jack of your inside radio setup and that broadcasts out to the Wireless Bluetooth speakers...
Pretty nifty to have and they sound great...
