Why would you need an amplifier to power your subwoofer’s output?

There are two types of subwoofers: passive and active subwoofers.

Active subwoofers get their power from power outlets. Plugging them into your wall will cause them to roar.

Passive subwoofers, on the other hand, don’t plug in to power outlets. They draw power from amplifiers. If your subwoofer is passive, you will need an amplifier to power it.

You might also consider using an active subwoofer with an amp. This is because some amps can add bulk to the sound. Some amps have controls that are necessary, such as the crossover or bass boost knobs.
