Did the 1990 GTA have the Performance sound option?.. I have those speaker pods that go into the body of the car and one is for the regular 6x9's and the other has a 4x9 and a 6" speaker i think in it.. I have both, but I dont know if my 1990 came with it, or is there anything i should look for to verify it has performance sound?.. the BEZEL around the dash had said performance sound on it, but the car came with like 3 different bezels...hellllp

P.S - by me saying I have both i didnt mean that both were installed into my car.. I just have a big collection of firebird parts for the past few years..
