Trunk Mounting - We have measured trunk temperatures as
high as 150 degrees Farenheit in the summertime. Since the
thermal shutoff point for the Power 360 is 195 degrees F, it is
easy to see that the amp must be mounted for maximum
cooling capability. Mounting the unit on the floor or top of the
trunk will not allow convection air flow across the fins. Even
better is to mount the unit vertically on a vertical surface, so
upward-flowing
fins. The Power 360 is too tall for this to usually be practical,
however.

mounted in the passenger compartment, mounting require-
ments are considerably relaxed, since the driver will not often
allow temperatures to stay anywhere near 150 degrees F.
Floor mounting is usually satisfactory in the cab, and under
the seat will work as long as there is at least 1 inch above the
amplifier
instance, the back of pickup cabs) is still the best.
Any situation which allows moving air to be directed over the
cooling fins will improve cooling dramatically. A simple fan
playing on the amplifier will improve cooling by a factor of 3.
There are situations where it is feasible to direct some of the
car's refrigeration air over the amplifier. In any case it is critical
that the amp not be enclosed in a box or covered so that air can't
flow.
