i tried to install my JBL GTO627 couple days ago, but the mounting bracket that came with it did not line up with the factory holes in the rear. Has anyone have these speakers installed? or i just need to return them and order other brand to fit my car? I looked up crutchfield and found that Blaupunkt GTx652 will fit. If anyone have these installed right now, i would like to know if i need to drill any holes or not, since i don't want to do any drilling into my car yet. ahha.

 

Someone correct em if i am wrong but i believe that you will need to drill holes for almost all aftermarket speakers since, if i remember correctly, the stock have only three holes and most aftermarket have four holes for mounting.
