Hey guys. I have a fair amount of experience with installs in my car, but it was only me driving it. I am getting ready to put a system in my Explorer, but space is more of an issue than it has been before. Questions I have: 1. Without sacrificing any storage space, where is a good place for the amp(s) and a subwoofer? What is the best way to approach this? 2. How do I find out what size speakers I can put in the doors? The depth of the speakers as well.
