130amp alt, 800CCA Battery, Stock Everything else. Enough?

[kicker06 10+ year member]

Ok, I have recently found out that I have a 130amp alternator (stock, nice huh?) in my 2002 Dodge Intrepid. I am about to replace my stock battery with a Duralast Gold from Autozone. It is $70 and puts out ~800CCA @ 32F, which I know is better than my stock 500CCA @ 32F Battery.

I had moderate dimming with 400wrms of speaker power and 800wrms of sub power (now going to be ~1200wrms).

Will my 130amp alt and 800CCA battery with maybe a big 3 be suffcient for ~1600wrms of power?

-The sub amp will put out ~1200wrms with 3 40amp fuses on the amp.

-The speaker amp will put out 400wrms with 1 40amp fuse on the amp.

(How do you calculate how much current they will pull combined?)

cca are good for burps day in and out playing you need capacity measured in aH. will your set up work as is? probably. perform at its best probably not.

You should be fine, I run this 1500 watt hifonics daily as hard as i can with low dimming on a 105 amp alt. remember when playing music u will never see your actual top power output for long enough time for it to matter.

Yea, I know you never go full tilt with music.

Isn't there a calculation to find aH?

depends on alot of things. that set up will work but being how a deep cycle works vs a standard battery you could be shortening the life span of the battery its dependant on enough varibles however one cant just say it will work great for a long time or not.

 

[kicker06 10+ year member]

The battery has a 3 year free replaceable warrenty, and an extended 8 year warrenty after that =)

A lot longer than I'll have the car probably.

I think I shouldn't be dimming since my Alt puts out my amps than I am drawing.

that is rpm dependant and you should read the warranty like when everybody says "get a red top for audio" red tops arent covered for car audio at all.

 

[kicker06 10+ year member]

Yea the guy at autozone said they are covered for almost everything electrical.

Is it true Hifonics needs seperate battery to get full power? (Alternator 130)

 

[kicker06 10+ year member]

Seperate as in a second one? It depends which Hifonics Amp.

As second one 1606D or 1605D............

to be noticeable volume wise doubtful. having a good battery designed for the task of an audio system is just a a better option imo. http://www.kinetikaudio.com/manuals/khccells.pdf read it and look at the specs. the model # of the battery shows the watts it is ment to power. hc2000 is for a 2000 watt system......

How much for the HC1800, could it be used to run entire truck (single cab=no space)? If there will be no sound difference why bother? Im just going by what Hifonics said "With my alternator being 130 only thing I have to do is change battery, if I dont max power will be 40% less than stated"...........

40% more power doesnt mean 40% louder there is tops a 3 db difference between 500 watts and 1000 watts. price of the 1800 is dealer dependant.

40% of 1600 is 640, are you saying there is no real difference with this? Is it even true about the 40% thing or is it just something to do with the warranty??
