you just need one, a general rule of thumb is that the wattage on your amp should be double the wattegae on your sub, hence if you have a 1200 watt sub you'll need a 2400 watt amp
To calculate amps, you need to know the voltage of the circuit. The formula to convert watts to amps is Amps = Watts / Volts. If the voltage is 120V, then 1200 watts would be equal to 10 amps (1200 watts / 120 volts = 10 amps).
The amps required for a device depend on its power consumption. You can calculate the amps by dividing the power rating (in watts) by the voltage (in volts) of the device. For example, a 1200 watt device plugged into a 120-volt outlet would require 10 amps (1200 watts / 120 volts = 10 amps).
To calculate the wattage of a device using 10 amps, you would need to know the voltage it operates on. The formula is Watts = Amps x Volts. So, for example, at 120 volts, 10 amps would be equal to 1200 watts.
Need to know the wattage to work out the amperage

Small generators are sized in watts. Watts is the product of amps times volts. To properly answer this question a voltage for your 10 amps must be stated. That said small generator outputs are usually 120/240 volts in North America. So 10 amps at 120 volts equal 1200 watts. 10 amps at 240 volts equal 2400 watts. A 3000 watt generator will be amply for your 10 amp load.
To charge a car battery you need aproximatly 8000 amps To charge a car battery you need aproximatly 8000 amps

1200 miles/(23m/g) = 52.17gallons
You need the formula: Amps * Volts = Watts But you get to do the math.
