I've just set up my RCA RT2350. First night, when a loud sound came out the whole thing would turn off and when i turned it back on would be pretty low volume. This happened twice. Next day, had the volume pretty low, and it shut off and would not turn back on. When it did, none of the speakers worked at all. It was also pretty hot to the touch. Is this permenate damage? I just upgraded the wire to monster cable. Is that too much? any help? Thanks.
