First off, you can't just hook the speakers up directly to the TV as it doesn't have an amp to power them unless it is a special TV.
Is the am/fm/cd stereo a car stereo or home style? Does it have a DVD player build it?
Easiest way is to get an all in one home style stereo/amp/DVD player and hook the speakers to that. Then you can program the remotes to work on both TV and stereo/DVD player.
Have fun.
