For a safety net, you decide on a 300A alternator.
Do You Really Need a High Amp Alternator?
Every electrical component in your car needs to draw some amount of amperage to function.
That can manifest as flickering or dim headlights, or your engine may even die.
In some circumstances, overloading an already anemic factory alternator can even lead to early failure.
How Much Alternator Amperage Do You Need?
Mostbasic audio componentsdon’t draw too much amperage.
For instance, a standard head unit with a built-in amp might draw less than 10A.
If you just need a little extra juice, a car audio capacitor may be a better choice.
