Pardon. What did you say. Speak Up When I see these big subs pumping around it always reminds me of the vibration lab at work, although that uses forced air cooling to keep the motors cool. A random video of a similar lab Needless to say ear defenders are compulsory in our vibration lab. Back to the guy above I would be most concerned about his giant lithium battery. You wouldn't want to short that out.
I guess there are some drops of awareness left in his mind , at 11:15 after another successful destruction he screams in panick " turn off the amp , turn off the amp".
