[QUOTE="pyro225, post: 6387778, member: 615550"] Back in the D. A. , most systems did NOT have fronts! Only those pimpin' 45 degree surface mount 6X9's! In my Ultra, though, believe it or not, there are 5 front speakers with the stock "Concert III" sound system (and 4 in the rear)! The front doors each have a 5 1/2" mid at the bottom of the door, a 1 1/2" tweeter atop near the window switches, and a single 3" (?) in the center of the dash facing straight up into the windshield. I've read in the factory manuals that the door speakers are set up as stock head unit amplified component speakers with a crossover between the mid and tweet. Can't find much on the center speaker, but probably for just fill. The rear speakers have their own amplifier in the trunk with a built in crossover. The 6X9's on the rear deck are low pass and the 3 1/2's in the rear doors are high pass. I'm pretty impressed with the sound of the system with stock speakers and amp. No real "sub" bass but plenty of clean volume and pretty well dispersed through the car (staged?). I'm not going to do front speakers until I've completed the above mentioned KQ9/Amp(s)/Subs/6X9 component set design. They'll be fine as they are as long as I don't blow them.... OOPS - that was a jinx! I think I missed the notorious GM "Monsoon" system by a year or two. I guess they sound even better than mine stock, but are a ***** to upgrade or remove and replace with aftermarket. Seems like GM got this one right, and it doesn't have the BOSE name on it!
