Once upon a time I had a problem like that. The thing I noticed was that when I
keyed up, it would peg a nearby CB FSM. Taking that as a clue, I made up a
sniffer coil and wired it to the antenna input of the FSM.
What I discovered was bad solder on a PL-259 connector on the back of my amp.
It had tested OK with an ohm-meter, but apparently the shield was not making
good contact with the shell of the connector.
For RF to get into a speaker you must have exceeded the FCC radiation exposure
limits, eh?
Good luck!
