Question: Do you need an amp for a subwoofer?

Subwoofers are designed to increase the bass frequencies, resulting in a deep, thumping sound. In most cases, they are paired with an amplifier to boost the sound. If you do not have the funds for both components, you can still hook up a subwoofer without an amplifier; it simply involves a little more know-how.

Do you need an amplifier for speakers?

Powered speakers do not need an amplifier. They have an amplifier already installed in them which is why they are called powered speakers to begin with. Depending on the speakers input options, you can hook them up to different audio sources without the need for a separate amplifier.

Is an amp the same as a subwoofer?

An amplifier will put out different amounts of power (watts RMS) based on the impedance load it sees. A subwoofer has impedance (measured in ohms) which represents the load an amplifier will sense on its output. An amplifier will put out different amounts of power (watts RMS) based on the impedance load it sees.

What is pre out for subwoofer?

A subwoofer pre-out is used for connecting powered or active speakers and subwoofers through an external source. High-end receivers usually have three pre-outs — one for the speaker and two for subwoofers. This allows the connection of both the speaker and the subwoofer simultaneously.
