Conclusion: These ultra capacitors don't give a huge advantage in the lanes as far as spl goes. Maybe a few tenths at the most. What they DO allow is better fuel economy when driving to shows. With these it's more affordable to get to the comps. They give our amps slightly better voltage on the input side. While that doesn't seem to yield a whole lot of spl, we know that it keeps these amps alive longer. So it's just easier and cheaper on the competitor than batteries. It also helps with wear and tear on the vehicle. Subs/amps/enclosure can be quite heavy, but their weight is able to be distributed. A battery bank is a heavy, centralized thing. It's weight cannot be distributed. It just sags the rear end and puts the U joints in a bind and causes a lot of repairs that otherwise wouldn't be necessary.
Super Capacitor demonstration and explanation.
I'd like to also note that I removed over 300lbs from my vehicle going from batteries to caps. It gained me fuel economy. Less wear and tear on my vehicle and MUCH more stable electrical for my stereo the way I use it. Also, this is 12 banks of the maxwell 3000F 2.7v caps. To make banks that would handle the voltage my alternator charges at from the factory (15.3.v) I had to put 6 of these in series. That makes the bank capable of charging up to 16.2v maximum. That does not mean this bank is 16.2v. It means it's capable of being charged up that high and no higher. Caps simply store whatever you charge them to. So since my alt charges at 15.3v, that's what the caps are. I have 12 banks. So each bank is 3000F (value of a single cap) divided by the number of caps (6) = 500F per bank. x12 banks = 6000F. So this is what 6000F of ultra caps will do when charged to 15.3v. My alternator is a DC Power 390xp at 600 engine rpm for the video.
