Then Ill buy a new battery and A new alt, not three new batteries

Iv ran 1k on my stock battery/alt with nothing but a 1 farad cap and never had any problems with lights dimming or anything.
Caps help regulate the power but cause more harm than good without a good alternator it makes your battery drain quicker. Depends on the size of the alternator and efficiency of the amplifier you can't guess what electrical upgrades you will need, sure with a really good alternator you might only need 1 really good battery but that's going to cost the same as 3 batteries and 1 decent alternator if not more.
Also unless you buy an alternator from:
Ohio Gens
Excessive Amperage
DC
Mechman
You're not going to run near amperage @ idle so you're going to need to be driving to play your system or giving it 1800+ rpms while idling.
