16v Batt?

[jcm1689]

would i be able to use this battery off a regular alt or would it require a special one that like put out 16v or something? im planning on using it as secondary for an amp and obviously i would need to add and batt isolator to isolate it from the batt in the egine compartment. would i be better just running a kinetik hc 800 under the hood and hc 2000 in back or would this be better??? the only thing runnin of it is going to be a incriminator audio 40.1? the truck its going in is going to have a irraggi 200amp dominator series alt if this helps.

If you want it to stay at 16v then you have to have a way to charge it to 16v.
