My son and I installed a Color DMD on a LOTR. After installation the sound on the back box speakers started producing a constant hum. There is no hum from the under cab speaker.
The two events would seem to be unrelated and the timing may be coincidental??
In any case, any insight on what may be producing a hum in the back box speakers and not the under cab would be appreciated. Is it possible they have two different amplifier circuits?
