We installed a new HD LCD tv w/ the built in DVD player (and new HD antenna) however the sound on the tv set is dismal. We have an existing newer Sony car stereo in our trailer and our first instinct was to wire the tv into that but fiber optics and 12 v don't play nice with each other apparently

The guy at Fry's recommended we look at a Polk soundbar and I have to say (and I know little about elec) it sounds like a good option -- it's wireless and the subwoofer can go anywhere (figured we'd stuff it in one of the closets and have our AS renovation guy add in a couple of new AC outlets so we could plug everything in. We're thinking of moving the TV to the big wall to the left as you come in the door (we have a 1992
Sovereign 21) and also mounting the soundbar on there if it will fit (not sure there's enough room -- soundbar is 35" -- and trailer isn't home where I can measure it). I thought about mounting it vertically, however not sure you can with this particular one.
The sales guy at Fry's said they sell a lot of soundbars to RV'ers -- anyone had any experience good or bad with them?
