Optimas Or Powermaster

[HUMBOLDT_knock]

I have two optima yellow tops for my audio system with a 5 farad cap and 140 amp alt. I am still getting voltage drop to the point my lights dim hard and I'm only running 2500w. Someone told me that my 140 amp alt. is not enough to properly charge my optimas. I think I'm gonna step it up to an irragi 300 amp alt. but I also want to add 2 more batts. Should I keep my optimas and get two more or should I go with four new Powermaster batteries?
