VON 2.1 Channel woofer works a few minutes then stops

 A customer called me concerning a woofer that she wanted checked by a technician. She told me that the woofer was dead. I was in a hurry, so I did not have time to confirm the customer's complaint, which is very important.

 I picked up the woofer on my way to my shop. upon reaching my shop, I applied the power, and the woofer was up and running. So I just kept it aside to do other things.

A few days ago I got a knock at my gate very early in the morning and I wondered what could have necessitated the visit and I almost came out armed.

Upon opening the gate I found one of my neighbor standing there holding a woofer and after excusing himself he told me that he wanted it checked urgently and he suspect it burnt after the power surge though I can’t remember experiencing any in my house.
