Caps are BAD NEWS altogether!! Go to www.innovativerides.com and check out the KINETIC batteries. they arwe the size of a lawn and garden battery(1/3rd the size of a normal battery) and are available 650amp to 2400 amp. Capacitors (also found in your amplifier near the power supply) dont provide what the amp is actually asking for...AMPERAGE. these batteries are awesome. Optimas are what lots of people use, but the AMP/hour these put out is like 390a-475a. So for everyone out there....NO MORE FARAD CAPS!
