Do I need a high output alternator?

I have a 2008 ford f150 supercrew. I have an alpine pdx 1.600 powering a jl tw5, a set of 5.25 inch alpine type x reference componets and type r speakers being powered by a pioneer prs-d4200f. Head unit is a pioneer deh-p710bt. All 4 gauge wiring. if not a high output alternator, any other electrical upgrades?
