Thanks but as I said I would like more specific info.
I read there is a 9 speaker option (premium), is that just a 4 speaker system with 6x8 2way drivers and the sub?
Also Crutchfield shows 3 and 4 ohm drivers will work in the Edge, they show this option for almost every vehicle, that does not tell me if the factory drivers are 2,3,4 or xxx ohm.
Also because someone else stuck some subwoofer in their vehicle that doesnt mean that they used the proper driver for the system, I can drop a dual 1ohm sub in the location but that doesnt mean thats optimum.
I will just break out my DMM and tape measure myself, seems like the only way to get the answers I need.
