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.
