I was just wondering if 4 of these batteries will be good for a car audio system. 2,000 watts RMS? This is the only best battery that I can fine in my own town. I can't get XS Power or anything like that. They do sell Kinetik at this one place but they are marked up 50% higher then SonicElectronix & I don't want to mail order any car batteries. There Shuriken batteries at another store too. there marked up high like the Kinetik. I like to buy them in store, If anything gose wrong with them. I can just drive to the store & return it. These Nautilus AGM Deep Cycle batteries are in stock ready to buy.

They do have nice specs but you do not need 4 of them for only 2,000wrms, hehe.

These specs are slightly better than Deka 9A31s which is pretty good for an alternative battery.

I'd say 1-2 at the most.
