As with every car I've ever owned, the first mod was the sound system. I've always been an audio enthusiast, and stock stereos make Dave a saaaaaaad Panda. After a fair bit of research, thanks to the gaping speaker hole in the Corvette's doors, I decided I had room to go with an active 4-way setup.
Quick break down of equipment:

SubThump partition subwoofer box

I didn't bother to take pictures of the head unit install. It's easy, been done a million times, and is a matter of following directions provided by Metra and PAC.
After the Head unit was installed, I tackled the doors. First step, cut adapters. I cut the lower piece out of 3/4 MDF and the tweeter mount out of 1/2" MDF.
Next, mount the speaker drivers to the adapters. This is where I had to get creative. The hole is big, but it was still a challenge to mount both a 7" driver and a 2" dome with a 4" flange. I measured exhaustively to make sure everything would fit. I had to cut some of the dome flange using my dremel in order to make it fit.
