Speaker turning on and off:
- Moving the wires, is this on the keypad or the actual speaker?
- What model is the speaker that is turning on and off?
- Has the customer switched the speaker with a different location / keypad? The phoenix connections are close together, touching the + and – together even a small amount of braid will give a reaction of shutting off (placing the amp in thermal overload by shorting the terminals).
Let us know if we can be of further assistance.
