I replaced the factory wall unit that came with our trailer 5 years ago with an automotive radio. Now, I want to install a headphone jack so I can use some wireless speakers. Would like to listen to the radio while outside the unit.
So, here is the problem. How do you install a headphone jack on something that doesn't have one? I'm thinking that you just can't tap into the speaker wires with the jack. Installing an A/B switch between the speakers and the jack seems to be the way to do this.
I'm open for suggestions, comments, or rude remarks.
