1. if an amp puts out 500 watts at 14.4 volts what about 13.6 volts

batteries usually run at 13.2 to 13.8.

With proper electrical, it's possible to maintain above 14V, that's why amps are commonly rated at 14.4 anymore. Either way, it's common sense, if it truly puts out 500 watts at 14.4, it will put out less than 500 at 13.6. There are various factors to determine what it's putting out so the only way to know for sure would be to clamp the amp and see rather than taking guesses.

well i can get you a ballpark estimate.

so @ 13.6 volts pulling about 35 amps you will be pushing approximately 475 watts.(remember this is a ball park estimate)

of course that is if you amp is actually pushing the wattage it stated it can do, so if you have a boss, quantum audio, sony, pioneer, power acoustic, or other cheap amps, your not pushing 500 watts.

and all this is not taking into account for the current being pulled from your alternator, if the amp is putting a strain on your electrical system, and your voltage drops even more, your going to lose watts also.

remember, the battery isn't doing all the work to push the amp, the alternator is.

Without knowing the exact amp you're talking about, it's impossible to say. Some amps are more sensitive to voltage than others.
