Panasonic home theater SA-HT730 Only speaker producing a muffled sound is the woofer! Have input set on radio. Older unit, only has RCA connectors. Bad amp? Power lights are lite. Display works. Not connected to hdtv or cable box. Can I test amp? Paid for Panasonic tech, no help! Thank-you!
 
The woofer is only supposed to reproduce bass. If none of the other speakers are working then it's most likely that the main unit is bad. Not likely all the speaker wires are bad. Since you are getting bass the radio is picking up a signal so that can't be the issue.
Here's a link to the manual so you can check you connections.

If you have another amp trying the speakers on it to see if they work would confirm that they do. You can use an old RCA cable and cut off the RCA at one end to connect the speakers to the amp.
