Hello all I am new to the board and this may be a stupid question but I just bought a 1990 Buick LeSabre and the wiring diagram that I found on the site doesn't say anything about the wiring for the two speakers by the windshield. I was wondering if anyone could give me any info on the matter. Any help would be greatly appreciated. Thanks

Just out of curiosity, why do you need the wiring info? maybe we can help you out with whatever you're doing?

I am going to attempt to install a stereo today, and I really don't have alot of experience doing so. Any help that you could give me would be great. I was curious because I'm pretty sure that the car has 3 sets of speakers by the windshield, doors, and the rear but the diagram that I found only has the doors and the rear speakers listed.

I'd have to say that's probably not true, or it has components (seems pretty unlikely to me)... Either way, a stereo is not going to have outputs for 2 pairs of front speakers. You'd have to use a crossover or just put them in parallel or series ------------- 2009 Pontiac G8 in planning stage

If all you're installing is a head unit, just use the right wiring harness and you won't need to worry about the speaker wiring. Usually they are wired up in series in the factory wiring but they originate from one speaker output as dragonrage pointed out. You'll still get sound out of all the speakers with an aftermarket head unit.

Well I installed the stereo and you were right I just went to Best Buy and told them what harness I needed and sure enough it was alot easier than I thought it was going to be. esmith69 you were also correct the front speakers were all on the same wire, so thanks for the input everyone.
