Can a sound system damage alternator?
Just being a sound system does not affect an alternator. However, if it used a large amount of current it may place a high load on the alternator. Basically the alternator is trying to make enough electricity to supply the car and the stereo. Today's cars use more electricity than older models.
Can subwoofers cause damage?

What is the benefit of A higher amp alternator?
You're able to reduce the depth of a battery's discharge—also known as cycling. That's because an oversized alternator produces more output at lower speeds, including idle. That increased output prevents the battery from having to help supply the load—and this keeps it at a more ideal state of charge.
Does A bigger alternator increase horsepower?
In addition, says Basner. “On some applications, a high-amp alternator can actually add horsepower to your engine's performance.” Sure, it's nominal, but, when it comes to horsepower, every bit helps. “Most alternators are only about 75 percent efficient.”
How many amps is A good alternator?
