Depends on the year. From 1990 to 1993 there is one amp under the passengers floorboard that is for the door subs and in the 1480 (only 1990)the internal amp runs the 4 in in the door and the dash tweeter. In the 1432 91 to 93 the amp in the tuner module in the trunk runs the 4 in and dash tweeter. In 1994 on the stock 5 ch amp is on top of the subwoofer enclosure behind the drivers seat. What is your year and problem?
