Author Topic: Upgrading TV digital to analog audio. 2000 Itasca Suncruiser  (Read 1177 times)

Hello all! I'm in the middle of upgrading to an LCD TV in my 2000 Suncruiser. TV installation/refab went great until I realized the old tube tv connected to the audio system via a 3.5mm headphone jack into some sort of amp I assume, only marking is AMP-3. New TV only has digital audio output (tos link), no biggie, so I bought a digital to analog converter, but I get nothing through the radio speakers upon connecting the DAC to the "AMP-3". Anyone have any suggestions? Is this AMP-3 just a small amplifier to boost the old tube tv output?  Wiring diagrams from Winnie are of no help, although they do show this AMP-3 component. I cannot find any other info on it.

Hi Ho:  The amp in question is by the passengers feet.  I found the diagrams to be right on and very complete.  The biggest problem was to make a surround out of wood that followed the curved plastic surround.  Or are you getting rid of the surround?  Anyway, I got rid of all the Itasca audio stuff and simply used a good receiver that gave real surround sound to everything.   Unfortunately we don't have that coach any more so I can't send pictures.
