Update!
This thing is a low end monster to say the least. I'm quite shocked on how good of a subwoofer it is. Been feeding her 1000 watts RMS for about a week now. She is laughing at it. I'm positive she can take 1500 watts RMS in the right box.
You're running 10,000 watts and asking these noob questions?
Answers:
1. As many high output alternators as possible.
2. As many batteries as possible.
MORE IS BETTER WHEN TALKING ABOUT ELECTRICAL. IT IS THE MOST OVERLOOKED PART OF A SYSTEM.
