Battery Question

Building my first big system and starting to beef up my electrical system. Can anyone tell me what to look for in a battery?

I have a friend who works for a business that is an interstate dealer. Can get me batteries at cost. It is a place that works on big trucks and diesel engines so they quite literally have some huge batts. This is what I was looking at...opinions on it please. I will be running around 3k RMS with a 220 Amp Irragi Alt a Duralast Gold up front ( it's only 3 weeks old ) and one of these in the trunk if someone says it will be a decent pick.

Interstate srm-4d

12-Volt Dual-Purpose Batteries (Used for both Deep Cycle and Cranking)

CCA 1314

MCA 1645

RC(Min) 390

Hrs. at Ampere Load ( 25amps = 6.5hours )

Also weighs in at 119 pounds heh.....whats 119 pounds when your building a big *** wall though right?

Anyways, any thoughts on this batt? At dealer price I will practically be stealing it.
