When Do Amps Begin To Take Power Away?

[Clocksta]

How big of an amp begins to actually start taking some decent power off the Alt? i'm going to be installing a kenwood KAC-6404 with my stock electrical, would this effect anything? or should everything be ok with such a small amp?

[AI James]

depends on car and lots of other things, real hard to tell you a specific answer

Do you have any vehicle info by chance? How many amps does your alt put out and what is the CCA of your stock battery?

If you arent pulling more than like 500watts max, then you would probably be all right.

With that Kenwood amp you will be fine...

i got an 03 Alero, i think stock alt is maybe like...100 amps? i think...= /

i think a 100 - 600 watt amp wouldnt take any power of your alt..just your battery thoug....but if your going over 1000 watts then that would neccesary need a bigger alt or extra's battery(s)

WRONG, some cars hella dim with a measly 400 watts

My brother caddy dimmed with only 400wrms

and it had a 140amp alt.....just goes to show you don't know until you find out what your cars idle pull with everything on(AC, headlight, etc.) before stereo.

Just happens that his model of caddy had a high idle load.
