I need some help

[cg2694]

I have a 03 jeep grand Cherokee limited v8

i just order an fi sp4 fully loaded and i was thinking about getting a crescendo 2000 or a 3500 haven't decided yet

What should i do about my electrical?

Should i get a new alt? Add an extra battery in the back?

I'm kind of new to this stuff so any advice would be greatly appreciated

well both would be prefered. some would say start wil an upgraded alt some will say start with a battery. personally i say start by upgrading your battery see how much that helps your voltage drop. next upgrade your alternator. if you are still facing serious voltage drop you may need additional batteries.

*edit also doing the BIG 3 should be first priority

What coils did you buy for the sp4? Do you have a budget for the remainder of your amp and electrical costs?

first of all i'd upgrade all the wiring in your jeep.

do the big three

and upgrade the charging path for your alt.

my friend on here runs a bc2000 full tilt on a fi Q and he only has the big three done. i don't think he has a big voltage drop at all.
