This is of the system with the cover removed.
Sally --
I don't want to rain on any parades... but have you given any thought to cooling that equipment when the cover is in place?
I don't know how much heat a McIntosh MCC446 amplifier generates (that will be a function of the rated power of the amp and the efficiency of the design and components of the amp) but it looks like that amp and crossover seal up pretty tightly in a small, well-insulated space with no external source of ventilation.
Chances are it will be all right, but you should toss a thermometer in there to keep it company and then after a few hours of use go back and take a quick look at temperatures, both air temperature and the temperature of the amp itself, probably there is a heat sink on the back of the amp for the output transistors. If you are finding any temperatures back there in excess of about 140 degrees F (60 degrees C) then you might want to take measures to lower them.
It is a very nice, clean installation, and I like that you haven't ruined the utility of the car, taking up every bit of room with amplifiers and subwoofers, etc. Does it sound as good as it looks?
