I heard it 3x different demos in the back seat, didnt get to sit up front, it was pretty cool, had my girlfriend sitting in the middle and her hair flew everywhere.
Thats normal, more power you run, the more heat your gonna have. As long as the subwoofer isnt smelling you should be fine. Remember, play it until it smells expensive
How would this affect factory computers and such running at 16v? I thought you would need a step down module for them? (i drive my off road jeep everyday)
