I have a 1999 GMC Suburban SLE with the AM-FM Cassette with a seperate cd player in dash below. It has 6 speakers, 2 in the front doors,2 in the passenger doors and two in the far back by the tailgate. I'm installing a Alpine cda-9826.The harness adapter that 2 stereo shops have sold me is missing the two passenger door speakers. Everything works fine but those two rear doors. Any help would be greatly appreciated. Maybe a wiring diagram for the GM radio or why those two doors are left out. Thanks
Well Jay...the problem is that you got the premium system (with oem Amp)!And those rear doors speakers drive by Amp. If you can read the wiring diagram then it's not a problem to reconnect in right way!Go to my web and take the schema.The Zip include both radio systems,premium and base.You need Premium but take a look at Base system too,just to compare: Click here!
