Battery confusion

[Tyde]

Hey I’m gonna run a 1920 watt rms system in my truck but I’m stuck on figuring on my batteries. I’ve been looking everywhere but can’t figure out if I can run my flooded oem battery as the starter battery and an agm deep cycle battery for the system. Like can I connect them by an isolator and have the alternator take care of them both with no issue? I am planning to pick up an alternator from singer to but I’m just stuck on figuring out my battery issue.

You can run them both together. No isolator.

Oh ok awesome. After properly charging the agm deep cycle the alternator should be ok charging both?

This should be adequate for 2000W or less. I'd consider upgrading to AGM under the hood whenever the original fails and you will want to keep en eye on the health of both batteries. One dead/dying one will hurt a healthy one.
