How much power wire needed?

[gearstix 0]

I'm going to be doing a big three. I'm going to have 1-2 batteries in the bed of my truck. I've got to wire up the Orion 2500D, which is also going to be in the bed of my truck.

Theres gunna be a camper shell over my bed, and the rear window taken out of the cab,and the front window out of the camper shell, and the box/amp/batteries is gunna be in the bed.

Should I just buy so much, like 25ft or what?

What gauge or gauges should I use? I can't remember what the amp can accept in regards to power wire size.
