Need Electrical Upgrade Help

[21Bravo]

I'm about to throw a new system in my truck, but I know I'm gonna need to upgrade my electrical in order to run it. The system will be 2 Fi BL12's in a 5 cubic ft. ported box being pushed by a Kicker KX2500.1.

The only upgrade to the electrical I've done is upgraded my main battery to an Everstart Maxx with 700 cold cranking amps. My stock alternator is either a 110 amp or 130 amp. I will be doing the big 3 in 1/0 before the system is in. After buying everything for my system I don't have a whole lot of money left over so I'm wondering if I should go with an Iraggi 220 amp HO alternator (130 amp idle) for $250 or if I should just put a 2nd battery in my backseat?

well...the alternator will keep your battery from being heavily strained...however thats not much of a battery...then again....the alternator will be doing alot of the work in your setup. 2nd battery wouldn't be that great, cause you don't have the charging system to support it properly. HO Alt, then spend the 130 on a yellow top optima.

yea, that battery seems pretty weak. I have a stock(orignal, 3/93 Manf. Date, amazingly) battery with 760cca. It is pretty big tho, it's like a big rig battery...

Considering that quote for a HO alt is less than a good quality battery (Kinetik, Powermaster) get the HO first. It's the best thing you can do to help your electrical system.
