98 Tahoe Battery Question

[lekwid8620 10+ year member]

New System will be 2 15hdc3's off of a crunch gp3000d-pro and a kicker 350/4 running pioneer comps up front and coax in the rear. I will be adding a 200amp alternator and 2 batts. My question is what is the biggest sized battery that i can fit in the front stock location?

I will be running powermaster batts, a d3100 in the rear and whatever the biggest that i can fit up front. Can anyone help me?
