I've seen the DIY speaker articles that have you leaving the factory speaker shell in. When you do this, is that for mounting a 5.25" or a 6.5"? I'm going to replace all speakers and Crutchfield does not show any 6.5" sets for the front. That could be because they assume the factory shell comes out and you use their mount bracket. That might make the mounting depth too deep.
Anyone with an 03-05 Corolla that mounted 6.5" components in the front? What did you use to mount them?
