Interested in great sounding bass? Adding a sub, also known as subwoofer, to youramplifier will give you the quality bass you’re looking for. Because amps contain anelectromagnetic component that boostselectrical currents, they are ideal for connecting to subs.

Since subs by themselves emit low bass frequencies that are oftentimes difficult to hear, it makes sense why you’d want to hook them up to an amp. The conventional formula prescribes one sub to one amp. However, for those who want to break with convention and take it to the next level, this article will explore what wiring 2 subs to mono amp entails.

The Clear Advantage Of Using 2 Subs

Clear and faithful sound quality is something music-heads live for. Wiring 2 subs to mono amp does exactly that, filtering away nearly all interference and increasing volume, thereby improving your listening experience.

You may be wondering how two subs accomplish this, and what the science is behind it.

In brief, increasing loudness makes bass sounds more prominent, adding depth to the quality of music. Loudness depends on the pressure amplitude of sound waves. The pressure amplitude is controlled by the volume of air a subwoofer is able to displace or move. With two subs you displace more air and increase pressure, thereby contributing to greater loudness.

Steps for Wiring 2 Subs To Mono Amp

Several steps before attempting a connection:

  • Check if your subs and mono amp are compatible
  • Pick up some speaker wire–the length and number of wires you need will depend on the number of coils your subs use
  • If your two subs have dual voice coils, prepare your additional wire for extra terminals
  • The terminals on your subs are internally connected to their voice coils and you will use them to connect with external devices. Locate the positive and negative terminals
  • Make sure your connecting wires are long enough to reach from the subs to the mono amp
  • Peel off the insulation at both ends of the wire, exposing the metal

At this point, there are two ways to set up your dual subs.

Parallel Wiring

  • Using the wire, connect the positive terminal on your mono amp to the positive terminals on both subs. For this connection, your wire should resemble a “Y”
  • Following thi
