Well, I just bought a 200 watt passive PA speaker system. Now before I answer this: Watts are not loudness, they are power.
Okay, so now that's over with. 200 watts is VERY loud in general. I know a guy who owns a 50 watt stereo, and if he turns is up ~50% people will complain. So if you are wanting to do a small band concert, they should be okay (make sure the peak power is over 600 watts), and if you just want to rock out a party until your neighbors call the police, those would be perfect. So in general, 200 watts would be fine for any application.
100 watts is great, 150 watts may be too loud for some, and there is higher watt amplifiers made.
To convert watts to amps, you can use the formula: Amps = Watts / Volts. In this case, to convert 200 watts at 12 volts to amps, it would be: 200 watts / 12 volts = 16.67 amps. So, 200 watts at 12 volts is approximately 16.67 amps.

200 watts
Zero. Watts is the product of Amps x Volts. As you can see an amperage value is needed. Voltage = Watts/Amps. Volts = 200/? 20 volts
It depends on the type of plant.
1000 watts is not twice as loud as 500 watts, that is the first myth to break. But 1000 watts will sound superior because of something called headroom. The best way to think of it is in relation to room size. 1000 watts will not rock Glastonbury but it will do serious damage in a pub or medium to large hall.
Each speaker is rated at 200 watts rms
Ignition 30 watts, fans 30 watts, driving lights 30 watts, headlights 100 watts. Total about 200 watts.
A small coffee grinder 100-200 watts.
How loud or how many watts it has.
A small shredder 100-200 watts.
