Secondly, should I buy a refurbished alternator? Rebuilt alternators can be up to 25 percent cheaper than buying a new alternator.

As a result, it might be more cost-effective to simply purchase a new alternator.

How big of an alternator do I need for 3000 watts?

3000 watts / 12V = 250A. You'd need a 250A alternator to keep up with it.

Battery could would depend upon how often & how long you want to run this amp without the engine running.

Do I need a high output alternator?


Amperage is basically the amount of electrical current your alternator can supply. That is, your alternator will only supply the amount of amperage a particular component demands—and no more. So high-output alternators will not harm your components or charging system, no matter how high you go with the amps.

Is a higher amp alternator better?

Not every vehicle requires a high amp, or high output alternator. A general high output alternator will provide more amperage, and in other words more power, but it will also increase the engine speed, proving itself capable of generating more power, but not being very useful in the long run.
