Actually if you check out
www.greenfilters.com they already use the same principle incorporated with their $300 twister green filter for crossfires.
If you have high - end home theater system, hyper voltage system is the same principle as the Monster Cable Voltage regulator and high - end gold cables. They make the sound much more cleaner and crispier and the colors much better than regular cables. With a 1000 watts subs in my trunk, although I have a separate battery for my audio system, I bet it still takes off some power in my crossfire.
