You may want to take a closer look in the manual to check if they're actually auxillary RCA inputs
or they're outputs
While I'm not familiar with your particular stereo, I'd imagine it's an RCA stereo output
used on a lot of car stereos to run a non impedence 'line out' to an amp that would power other speakers or a bass unit.
I replaced my trailer's stereo(AM/FM/cassette
) as soon as I bought it with a $100 JVC unit from wally world so I could play mp3 cds and have an 'in' jack for other components like a DVD player, TV, ipod, zune, or computer audio. I'd hoped the same for mine when I ran RCAs for the TV sound to the stereo unit but only found one set of RCA jacks in the back, an output.
With my new unit, the only input is an 1/8" stereo jack on the front of the unit.
They do make higher end stereo receiver's with rear RCA inputs, I just sorta doubt they'd have installed them as an OEM radio.
You can replace your stereo with a DVD car stereo player that I know has rear RCA ins. You can check out a few reasonable players at Walmart (they start around $199) I hope I'm wrong and your unit has the 'ins' and a $3 RCA stereo m-m cord does the trick for you!(... if your TV has RCA audio 'outs'
