Cool running Amp?

[Mike in Boston]

A few years back I owned a Sunfire home amplifier that I loved. The thing I liked best was that it didn't generate any heat and didn't even have any heatsinks. Does anyone make something similar for car audio? This way you could mount the thing in a tight area without the need for air flow. I was just curious. -Mike

I have an arc audio (at least 115x2) after playing max volume, in an enclosed area, for an hour... its so cool to the touch that you wouldnt know it was running. They run about $400-500 at this power.
