Do you have a 6 or 10 disk CD Player.
They could maybe for a sat-lite receiver over driver side.
Do you have a unit like this
If they are behind the TV and you have RCA output jacks on it they would work thru Aux unit to play over the stereo radio spk's.
If you have a Stereo Surround sys than they may work thru stereo receiver for surround sys.
