There is no way to tell, you don't have enough information.
Watts are what you get by multiplying the amps x the voltage. Simply put, Volts X Amps = Watts.
To answer this question a voltage must be given. Watts = Amps x Volts. <<>> Answer At 115 volts ac, 30 amps equals 3,450 watts.
30X240=7200
Assuming you mean 12 volts, then you cannot run any 78 Amp fans. Unless your fans run at 0.38 volts, there is no way to draw 78 amps from 30 watts.
30 amps at 120 volts is 3600 watts. 30 amps at 240 volts is 7200 watts.
The Audiobahn amp A2601Q model has a maximum power output of 2600 watts.
The Alpine V12 MRV-T501 amp has a maximum power output of 500 watts.
There is no such thing, 30 watts is 30 watts. "Line in" is normally about 1v peak - to - peak. So if your 30 watt amp has a "line out", no problem. An amp can be modified to have a "line out". Similarly, an amp can be modified to accept larger inputs without damage. However, driving an amp straight from the normal output of an amp, although possible, is fraught with danger and expensive consequence and should be avoided at all costs
The maximum wattage that a 30 amp breaker can handle is 30 x 230 = 6900 watts. Other variables come into play and this number will decrease depending on the load, duty time, and difference in voltage fluctuation.
A 15 amp circuit can safely handle up to 1800 watts of power.
120Watts=1Amp
The formula for watts is, Watts = Amps x Volts.
Total power output (Total RMS output): 1000 watts
