1989 ez go, if you looked yes it had a subwoofer. I've owned this golf cart for years and have made it my own project. Lots of fun. It had a lift kit, bigger tires. New belts, completely went through the carb. Runs well. Robin 2 stroke 1 cylinder. I added the roof, the radio, two group 31 battery's for the amp and subwoofer with marine battery shut off. Added the light bar and some blue lights for the dash compartments. Selling to upgrade to a newer golf cart. Will trade for 4 WHEELER
