Re: 1969 Camaro SS 396
First, welcome to Team Camaro!
RPO U57 tape deck is listed as having four speakers, and from what I recall off the top of my head, is separate from the optional AM push button radio and in-dash speaker. The info should be in the 69 Assembly Instruction Manual (AIM), so if no one can answer better before I get home and have the AIM in front of me, I will post what the AIM has on the subject.
69 'vert project big block/TKO 600 RR
68 'vert driver RS clone -- gone!
