[Help me choose the proper charging setup]

I have a 03 acura tl with the fallowing equipment.

Sundown saz-3000

Sundown 2- x10's

Sundown 125.2

Memphis mclass 6.5's

Sundown 125.4

Memphis mclass 5 1/4's and 6x9's

I have a optima under the hood and a shurikan 60 in the trunk.I want to have a good steady voltage which i'm thinking i need a bigger alternator(mechman?) and maybe a pair of XS 3400's.Before i waste my money experimenting can someone suggest what i really need?
