Bose amp relay location

Does anybody know where the Bose amp relay is located on a 1990 corvette convertible? I believe its draining my battery. Thanks.

Inboard side of the steering column. Remove the carpeted hush panel. Remove the aluminum reinforcement. There are relays on each side of the column. The amp relay is on the inboard side.
