Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.

Can you measure the resistance and voltage on the speaker wires when the system is running, and let me know the results?

You can also use a multimeter to check for any shorts in the speaker wiring.

Let me know what you find.

O have a millimeter. Not sure which setti g is for checking reaistance.. last night i went out n it was playing.. but will stop eventually...

Use the Ohm setting to check for resistance.

If it is playing intermittently then there may just be a loose wire or a bad earth somewhere.
