Yeah. But, I would much rather take a larger amp than a smaller one. Purely because I live in Florida, so my trunk gets hot, and I like having my amps have more surface area for heat to dissipate from. If a small foot-print amp can boast the same amount of cooling, somehow, I'd take it up.
That's the whole point. The HD amps are said to run cooler to begin with - so they have effectivly done what you ask //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
"HD amplifiers start out with a big advantage in that their advanced Single Cycle Control™ Class D technology generates very little heat to begin with. To make sure that the heat does not build up to levels that compromise performance, the HD's utilize dual cast-aluminum heat sinks with vertically-oriented fins that effectively dissipate heat, even when the amplifiers are stacked together with our optional stacking kits.
And, in the rare event that an HD amplifier reaches an unsafe operating temperateure, our unique "never quit" Advanced Rollback Protection circuit will adjust power until the amplifier cools down, without ever shutting your music down. "
