How do you know if you need an amp capacitor?

Answer:

Without knowing your sytem power requirements, how many amplifiers and how big they are, etc, it is hard to give a definitive answer.

However, if your headlights dim on large bass hits, or worse yet are "dimming with the beat" then it's pretty safe to say that you do need a cap.
