Anyone know wats the max wattage for amps i can take from a Cinq Battery, Dont think its a normal battery anyway as it looks a lot larger, more of a performance one, but a std cinq battery will do, and ill know this will have enough.

Basically i got an Amp running at 1000w running two 1000w 10" Subs, and Now i want another amp to run a 15", Im thinking just a little one like 600w, i dont really want another battery to charge up, and a cap wouldnt help in this arrangment would it? Would i get away wit a more powerfull performance battery designed for ice if the one i have now wont hold its charge?

Anyhelp appreciated thanks.
