Jerry's dual speaker bracket pics.
I did the same thing. I bought my brackets from a FABO member. I was replacing my dash pad and it was the perfect time to install the speakers. I went Infinity Kappa all around. The car rocks. I have an extra sub and amp laying in my garage, so that goes in this winter. You will like it. You did a fine job. I didn't insulate my top, but I think I will do that this winter as well after looking at yours.
I have a Dart Sport and my package tray has no strength to hold speakers, so I bought some nice 6X9 boxes and an Alpine amp to run them. They work slick pointing up.
