It's watts divided by volts equals amps.
Example: 1200 watts at 120 volts is 10 amps.
To get the watts if you know the amps, multiply the amps times the volts. 10 amps at 120 volts is 1200 watts.
An 8000 watt generator at regular house current 110v will supply 72 amps.

1/2 amp.
1 amp
That depends on the voltage.
700 watt is 0.93871 horespower
There is no volt meter or amp meter in a DC watt meter.
1200 Watt wiring is more than enough for an 800 Watt amp. The rating of the sub doesn't make any difference to the cables. If you want to use the sub to its rated power you should get a bigger amp. If the amp can only give out 800 Watts and the sub can take 1100 Watts then you can put a bigger amp on. It is still going to be loud as with an 800 Watt amp. I have a 300 watt amp with a 1200 Watt sub and people hear me coming.
800 watt should be fine
About 1/2 amp.
An 8000 watt generator at regular house current 110v will supply 72 amps.

50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.
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
a watt is power, or 1 joules sec= 1 watt an amp is 6.242 × 1018 electrons passing a given point each second,
