So like many I removed the factory amplifier, nav, bluetooth, etc and replaced it with a nicer aftermarket system. As part of that I measured and made a custom bracket to allow an amplifier to mount in the factory location so as to be completely stealth once installed. Just test fitted and it was spot on. If anyone is interested I can try to create a PDF template and/or load a solidworks part or drawing file for CNC'ing. I used a simple 24"x12"x0.25" ABS sheet from McMaster which can be bought for around $24. I'm still finishing the install so excuse the ugliness of the pics but I figured I'd share.
