Does anyone know if the 1990 Cadillac Eldorado Biarritz had a six- speaker system? This particular car has the factory Symphony Sound system, not a Bose. The question is were there speakers in the dash in addition to the ones in the doors. I am not near the car and friend wants to upgrade system and needs to know how many speakers in the front: 2 (in the doors) or 4 (doors and dash, also). Thank you!
All the information I looked at shows only two front speakers in the doors.
