I recently bought a new RV. You can see it here.
Bought a New Class A RV today
I was surprised when I found that the 32" TV isn't connected to the four house speakers in the roof of the unit that are feeding from the dashboard radio/CD player.
Coachmen suggests I go to an Audio store to have them run wire from the RCA audio outputs on the back of the TV to the radio/CD player in the front dash. Or do it my self, but I don't like the idea of drilling holes and running wires in my brand new RV.
I thought of plugging an RCA stereo to 3.5 mm plug into the back of the TV for the external speakers , and a stereo wireless transmitter and matched wireless receiver into the auxiliary input of the radio. Like this
Amazon.com: Audiomate 3.5mm Wireless Audio Transmitter - 2.4GHz Digital Stereo sound Sender and Receiver with Built-in Li-ion rechargeable battery - Compatible with any earphones and active speakers: Electronics
With it running through the radio auxiliary input. I can control volume, bass, treble, fader, balance, etc. It says the unit will transmit 20 to 20K frequency and the reviews say 20 feet or so doesn't lose sound quality. I can do this for around $55. Any down side?
