That's a good idea, I'd like to find any reason to not have to spend the
$$$ (145) to replace it. Thanks!

The temp shouldn't cause it to blow fuses. Consumer rated silicon is good
from -20c to +70c (158F) and most electronics intended for use in a car are
industrial temp rated, -40c to +85c (185F) or automotive rated, -40c to
+125c (257F). I grew up in Chandler, and remember the heat. It was bad, but
shouldn't cause a failure like this all by itself. I make industrial
controllers for heavy equipment, and they have to handle similar conditions
when the control box is in direct sunlight. I've never seen a failure from
ambient temperature alone.

Have you tried unplugging all the outputs on the crossover, so the only
connections are the +batt and gnd? If it still blows fuses with no load
connected, it's time for the repair shop...
