C&D UPS12-170FR Battery Question

[BigSix 10+ year member]

Question for all battery experts, I went down to houston to pick up some stuff for a friend and picked up this C&D 170fr- for a good deal while I was down there. Im currently working a setup in my car with a 3000-4000 watt system and was wondering how many of these should be supplied for that kind of amp? Plan on getting an audioque3500 or a sundown 3000, already have big three and 1/0 guage wire. How many watts will each battery be good for?? should I get bigger C&D batteries or add some more of the same one?
