You will not be able to constantly play a 3000 watt system at full volume with a 170 amp alt. But if that's the biggest you can get, you're kind of stuck.

BTW what companies have you contacted for alternators? I have a hard time believing that neither Iraggi or Ohio Generator can build you alt bigger than 170.

With 1500 watts the 170 amp alternator would be great.

ok if I get 2 stock alts for my car =ing 180 amps and get another battery will I be able to run 3000rms cuz of the whole A x V = W think there you take 3000rms and divide from 13.5 volts to get 185.13 amps, so would that work, with the big 3 or not

477.95 is crazy for a 170 amp alt. Please do not pay that much. Look on ebay for Iraggi alts they have good prices and im sure they make one for your vehicle.

Ok first of all, 3000 / 13.5 = 222 amps. Then you have to multiply that by 1.2 to account for efficiency = 266 amps.


Trying to run dual alts is not even possible on a lot of cars, and will cost you a ton when it can be done.


That price is high for an alternator, but with some cars you have no choice and just have to pay it.

i know this is a noob question but how why do you divide it by 13.5? and then you multiply it by 1.2 because its underrated right?

13.5 volts. Alternator output is 14.4 but there is usually some voltage loss. You * by 1.2 assuming the amplifier is about 80% efficient.

Get a car audio battery, not a regular car battery. Kinetik, Odyssey, Stinger are the good ones.

Northstar makes some batteries that are super powerful, but you don't want one under your hood. They are not designed for automotive applications and don't hold up well to that environment. They are great for mounting inside a vehicle, but expensive.
