No overheating yet - and its been 100+ degrees here lately. But that Boss runs pretty cool. Mind you, if I touch it after the car's been sitting in the sun, it is quite hot - makes you almost think you'll get burned (but you dont). But then, its no hotter than the little metal stickshift insert.

The Boss doesn't have any installed fans either . . .

 

Nice! I have some typer Rs too waititng to be installed...I was wondering how you mounted the tweeters? They appear to bigger than the stock ones. Thanks man!
