well my 97 gt does not have bose , but it does have the 4 inch speakers beside the 6x9 in the rear 5 1/4 up front . but if you are putting subs in the trunk ...TAKE THE 4 in SPEAKERS OUT !!! it help the subs breathe better and louder , 3 db gain just by doing that and it helps the rear speakers from distorting so bad cause the pressure crated in the trunk will push the cones on the 4's and 6x9 up hence why bass offs and db drag measure in spl (sound pressure level ) its a good move to make ... look and see if you have 4 inch speakers beside the 6x9 and get back to me
