Exclamation How Many Watts Off A 90A Alternator?

I drive a Mazda 3 with a 90 amp factory alternator. What is the most number of watts from an amplifier(s) that can be used without crapping out my alternator? 1800 watts?

I will be using an Optima red top (would switch to yellow top if necessary) to replace the factory one and 4 farad caps at a minimum, as well as the "big 3" upgrade.

90 amps x 14.4 volts equals.....watts, throw in a 4 pack of energy holders and on a clear day, you might get what you're looking for.
