Definitely! Orrrr well it more less allows air to pass above and below the amp helping some of the heat to get away from the Amp rather than being trapped.

I've seen it done many times and also adding computer fans one on each side of the air vents on the amp to help circulate air over the circuit boards inside the amp. I'm still kicking myself for not doing this, totally slipped my mind....
