Time for an update: On the left is the speaker box installed. You can see the CD changer in the middle of the box.
The lid over the CD changer covers a storage bin for the 4 extra CD magazines I'll carry on road trips.
I have a total of 5 counting the 1 in the changer. That means I can carry 60 CD's total.
Depending on the CD's I pick, I'll have from 50 to 65 hours or so of music available.
At 6-8 hours per day, I figure I'm good for a week to 10 days without repeating.

On the right I'm test fitting one of the 2 amps. These amps are HUGE physically. About 19"-20" wide.
So I had a heck of a time figuring how to mount them in the space available.
After they are mounted an open face box will be built to cover the edges of the amps and hide all the wiring.
The Infinity logo and the blue stripe will be visible. The box will be covered in the same material as the speaker box.

By the way. The photo on the right gives a better representation of the actual color of the box.
Not sure why the one on the left looks so washed out. To much flash I suspect.
