I am in the process of finishing my install (www.sounddomain.com/id/boomintaurus
). I had put 8" midbass drivers in my front doors, and I actually went the route of drilling a new hole in the door and frame of the vehicle. There was a company that i found that sells rubber door boots rather cheaply. It worked out perfectly. I'm an installer so i'd say the majority of the tools i used wouldn't be found in a common tool box.
