17 volts? Who are they kidding?! 14.4 volts is normal at idle and 12.8 volts is normal during a bass peak. I'm not sure that 17 volts is possible without a MAJOR overload of your vehicle's electrical system. Even with 8 batteries and 3 high output/high voltage alternators I'm not sure that you could achieve 17 volts. However it does sound like you have a stable electrical system which I would be happy with. If you want to reduce the voltage drop then try a capacitor. I'm not very familiar with dry cell batteries so that may already be taking the place of the cap, I guess I don't know for sure. MA audio is a bit overrated (assuming that your MA audio is a Mobile Authority amp and not a Massive Audio amp)and try to look bigger and badder than they really are.
