If you wire batteries in series the power adds up right?So if I take three 6 volt batteries and wire them in series it makes it an 18 volt load.Will a 12 volt charging system be able to charge this load and if so would amplifiers be able to take it?It seems if they could you would get significantly more power and gain some db's but I did read something in Car Audio a few years back about too much voltage will kill your amp but how much voltage is too much?
------------------ Thanks Hurricane for all your help

voltage for the amps first depends on regulated or unregulated power supplies. some amps do not need higher voltage to produce or exceed there rated power outputs. 18 vdc to most amps is really to much. it is my experience that in the neihborhood of 14vdc to 16vdc is best for most amps. you are correct about the wiring of the 3-6vdc bats to make 18vdc, but you will have to provide some other means of charging the system other than a stock 12vdc charging system....i.e a after market alternator(leece-neville) with an externally variable voltage regulator. hope that this is of help to you

to charge that setup, you would need a 6 volt charger or a 18 volt charger. since neither are readily available for a car, i wouldnt suggest trying it simply because it would be very very expencive. now, you could run your system off of batteries and recharge them every night when you got home if you wanted to, but when the batts run down, no more music until you recharge, because the stock alt. couldnt handle it, unless you used a relay to change it from the batteries to the car electrical system, but in that case, they would be getting 12-14 volts, not 18.
