looking at 2 shuriken sk-bt80 and running a full system 1200watt kenwood 5 channel.

anyone have any idea of approx how long i will get before these 2 batteries are drained?

Sure I can if you are wanting batteries for use when the car is not running your going to want batteries specifically designed to be drained way down and then recharged.

Most AGMs but not all are not designed that way they are designed to give big burst of power for a short time.

Deep cycle batteries are more suited to your needs whether they are AGMs or flooded cell batteries.

So if you buy the battery best suited to use with the car not running you will get the best results and save a bunch of money.

You can find a lot of good info on this topic pretty easy with google

Hope this helps
