Ill be getting the following Amps.

PG Xenon 1200.1
PG Xenon 100.4
Pioneer DEHP8MP (60x4)
and a 12disk changer.

do i need a new alternator to handle the draw of this?

 

No just get a good Cap!

 

a batcap 400 or supercap 100 will work best.....I'm looking into them as well....he'll if we get enough people we may be able to save some in a GD
Read into them-

I would also get a yellow top optima just to be on the safe side. Also don't run that setup with the car off.

 

Thats a good advise! Youll Drain your Bat

 

So im Ok if i run it always with car on?, I just got a brand new costco battery with 640 CCamps. Is that cool if i got a Capacitor with it?. I thought that caps were a catch 22 since they pull power from your alternator/battery anyway and then after they empty they start pulling again.

 

caps are worthless, they do nothing but stabilize voltage drops, not maintain ideal voltage itself- and they can contribute to ruining your alternator

A Xstatic Batcap is a hybrid between a cap and a battery, it shares the discharge characteristics of a cap with the reserve and cycling properties of a battery in a package that is very small- less expensive than the "for show" only 3-5 farad caps, and packs enough juice that you can start your car off of it if ever need- Read into them and see why competitors use them, they have several models-wether for burps only or for full cap applications

If you are running 1000+ rms on a stock alternator, its very much worth the investment to have less strain on your electrical system

 

i don't have a cap

i been meaning to buy one but i never get around to it

 

well dont waste your $$$.....how does one push 200-240amps of current from a 105/130amp peak alternator and expect 1-5farads to actually help- not to mention your alty has to run other accessories.....
