Hi Semilive - I know that if my cell phone (Blackberry model) is in my car in the heat in the afternoon....it conks out) - so far each time it did that it came back after the air conditioning brought the temps down. I have been storing my sound system in the garage for years and in the summer it gets insanely hot in there (120ish?). I know it's not good. But so far I have not noticed any detrimental effects. I've also had my Crate battery amp out in that heat for 4+ years. I did lose my lead acid battery on the Crate a year ago (maybe 3 years use) but I suspect it may have been from overcharging (leaving it on the charger once the battery had a full charge). Air conditioning for my garage is on the top of my list.

Best of luck with your heat challenge! Keep us posted!
