Williston Audio Labs is great if he has done your amp. Even if he hasn't done your exact one, you can probably find from that brand and get an idea.
CAF is THE MAN. I went from a functionally good setup, to what I'm about to finish up thanks to his videos. Here is in my regular cab pickup. All installed, and would not compromise seats going all the way to the back, and where I like them even without it.

No clue if its going to get too hot, hum, or if the black acrylic it's mounted on will hold up. Should be fun to find out... Looks like it's mounted on black mirror / deep tint. (the top of this shows what it looks like). As if the back glass is twice as tall, and the equipment is mounted to the glass.
