Greetings, I'm looking to purchase some good Mid's and High's for my 97 Burban. Nothing too crazy (pricing), I need to upgrade my stocks since the install of two kicker 12's. I think it calls for 6 1/2 in the 4 doors, and 4x8's ??? above the rear doors. I'm gonna want to add an additional amp. Suggestions ,experiences, or likes please and thank you.
