I WAS GIVEN A SUB FROM A BOSE ACOUSTIMASS POWERED SPEAKER SYSTEM, 1989. S/N 224938
D.O.M. A9431... WAS TOLD IT WAS WORKING WHEN IT WAS STORED AWAY. NOW WHEN I PLUG IT INTO A WALL ELECTRICAL OUTLET. THERE IS NOTHING. NO NOISE OR ANYTHING. EVEN WHEN I TURN IT ON. WHAT COULD BE THE PROBLEM???? AND HOW CAN I CHECK TO FIND OUT WHAT THE PROBLEM IS??
THANK YOU
