Not to hijack but when is it recommended to go with 3 batteries over 2? I have two now but was thinking of adding another and getting a Prosport20 plus charger. Also, when should someone think up upgrading the alternator?

Right now I have two amps and probably by the end of the summer I will have three. Two Syn4s and a syn2 if I add another set of tower speakers in the future it would be another Syn4 for a future total of 4.
