[QUOTE="kreapin, post: 8362927, member: 614592"] They don't like to be run daily at half there recomemdend impedance but .75 on the 1 ohm versions daily with proper electrical is fine. .5 for burps is fine with proper electrical. That is from my experience with mmats amps. I ran a .5 ohm version daily at .35 and blew it within 20 minutes but mmats repaired under warranty and the bench tech apologized, after I explained my setup he returned my amp to working order. Never had an issue again, .35 all day and was lovin it. No heat. Just remember it has a floating ground. Don't bolt it down to metal or a sub box, they don't like that kinda stuff. Simple rules I have come to understand with mmats amps. Don't be cheap with electrical, although the 4000 is not as power hungry as the 3500 and yet turns out quite a bit more juice. The 4000 does not have the protection circuitry as the rest of the line up. [/QUOTE]
