hi, i jsut purchased an rca model number rt2770 home theater system. it is just an am/fm and tv/dvd reciever. i hooked it up to play cds through my dvd player and just bought the sirius radio home docking system. i got everything to work as planned but ONE speaker gives off a lot of crackly static. but it only does this when the sattelite radio is on. otherwise the sound is crystal clear....any takers?
