That depends on the total power, the efficiency of the amplifiers and how you normally use your system.

Oftentimes a cheap overseas alternator that boasts big amperage is not really much of an upgrade once you get past the deceptive specs. To do a quality and sizable alternator upgrade you will spend a lot, will need to change belts and pulleys and perhaps upgrade the power and ground feeds. I would make this my last step after first concentrating on my battery reserves and a robust AC shore charger.
