some1 told me that to figure out how many watts your amp will push with over 14.4 volts just times the fuse size with how many volts the car is putting out. well i did that with my kicker kx 200.2 and according to this idea my amp is pushing out about 450 watts which is impossible so what did i times wrong or what?????????? the amp has 1, 30amp fuse

Usually when you use the fuse, it only gives you a rough estimate, and also, that figure would be with the amp running at 100% efficiency-nearly impossible, take off 40% and then the figure might be a bit more realistic.

30 x13.5=405 405 divide by 50%= 202.5 watts
30 is the amp fuse size, 13.5 is close to what your car will be running in volts, 405 is the max watts, 50 % is how efficient the amp is, 202.5 watts is around the rms for that amp. If that amp is more than 50% efficient and you get 14.4 volts, then you will get around 250 watts.
