Is my alternator powerful enough...

i got a dodge stratus 04 and im putting 2 1500 watt amps into the car to power my 2 subs but does my car have enough to power both? if not can you please explain what i need to get to make it so it does

thanks im a newb to this kind of stuff

What amps and what ohm will you be wiring the subs

how many amp alt? battery? big 3? amps? impedance load? etc.

one would need a lot more information to answer your question.

x2 but if its truly 1500 rms a piece, ya i would say you need to upgrade

Stock..?....no....dual 200 amp alts and 4 extra batts and you should stay at 13-14v

HE DRIVES A DODGE STRATUS!!!!

Can you do 100 push ups in 20 seconds?

But like they said, if you're doing that kinda power, do the big 3 and add a battery in the back and make sure the one up front is up to par too.

For 3k watts he is going to need a High output alt as well

If you think it takes 400A worth of alts and 5 batteries to handle 3k you're retarded.

i was gonna say...highly overkilled

You are right. I highly doubt he's gonna try do that kind of power and not know how.

He will probably need at least a 150+ amp alt though right?

lol true that

should be ok with a HO alt, and an extra battery, big 3

or may be able to get away with 2 kinetic 1800s or 2400s, big 3

stop speculating until we find out if they're truly 1500watt amps. I'm betting around 400RMS each...

At idle he'd get about 200 amps, pumpin a true 3000 watts @ idle will draw about180 amps....

Ad in A/C and vehicle ignition = 30 more amps so now at idle we are up to 210 amps

Get up to 1200 rpm then most likely he would see 300 amps which will keep the batts charged up from any stop and go traffic.....

Now if there are no stop lights and you only drive the freeway then no that much amperage is not needed to keep a steady voltage...

And Notice I said "STEADY VOLTAGE" meaning not dropping to any lower than

13V as in 13-14V like I posted...

Now if dropping to 11 volts is ok than 1 extra battery and a 150 amp alt will work.

I had a 90 amp with the Big3 and 1200 rms and my voltage would drop to 11.5 at idle and down to 12.8 @ 2000 rpm when hitting bass notes

So with my ghetto math 2 1/2 times the power = 2 1/2 times the alt which = 245 and thats to get a voltage drop like I did, which you dont want...

Maybe a little over kill but to keep a true steady voltage and charge everything run everything, it's not unreasonable
