Was wondering what the best material to put on top of an amp to dissipate heat...

I have no choice but to put my small factory harman kardon amp on top of my Phoenix gold amp b/c of the short factory wire harness. (the amp is tied to the rest of my speakers... and I've tried to move it/my new amp, but can't).

Is there a material that would alleviate some heat on top of the amp if the other amp is on top. Right now, i have plexiglass on top, but I don't know for certain whether that will melt or not.

If the Phoenix won't go anywhere else, you can lengthen the wires on the Harmon Kardon to put it where you can.

My ex once told me I have a perfect face for radio.

Heat is transferred by one of three methods: conduction, convection, or radiation. Radiation only applies at very, very high temperatures - nothing an amp will ever see. Therefore, if you can increase convection then you can increase heat transfer from your amp (which cools it off). You can increase convection by installing a fan.

The other method you can work with is conduction. Heat conduction takes place by heat traveling through a conductive surface like metal. For example, take an aluminum rod that is 12 inches long and hold one end in a fire. The other end will eventually get hot because the heat conducts up the rod in the direction of "from hot to cold".

The best bang for the buck is to increase convection (add a fan). Your amp was designed to work in hotter than average environments anyway so heat may not be as big of a problem as you think.
