The quick answer is no. The TVs only use the built in speakers, unless you have added a sound bar.
That's the same speaker setup as in my Vegas 25.2. My speakers in the living room are connected to the radio. Can adjust the balance with the equalizer settings. The speakers in the bedroom are connected to the rear radio. It has an A/B switch to control either them or the outside speakers, or both.
Suggest you call Thor and ask for all the schematics for your rig. It will tell you how things were connected.
Bad decisions make great stories!
In our Freedom Elite, the dash radio plays over the dash speakers and the two under the forward cabinets. The radio in the bedroom plays over the bedroom speakers and on the outdoor speakers. The TV uses its own speakers.

We added a Bluetooth transmitter to the bedroom TV (via the headphone jack) and paired it with the rear radio. Works nicely; we even have sort of a surround sound stereo effect. Since your front speakers are also under a cabinet, that should work there, too.
