HO Alt for 2004 Sentra?

[c_hayhurst 10+ year member]

I am saving up to buy a 2000-2500W subwoofer amp for my 2004 Nissan Sentra.

I currently have a stock electrical system, a 250W amp running my speakers, 4 AWG wire from the battery, and 8 AWG wire to the existing amps.

What do you recommend I do in terms of a battery, alternator, Big 3, etc. when I upgrade to such an amp?

Best as I can tell, the stock alternator puts out 80 Amps. If I need a new alternator, who do you recommend I shop with?
