Introduction

Greetings! Allow me, an experienced audio engineer, to shed light on the intricacies of connecting subwoofers to mono amplifiers.

Can you connect two subs to a mono amp?

Yes, it is feasible to connect two subwoofers to a mono amplifier. However, careful consideration must be given to the impedance of the subwoofers and the amplifier.

Impedance Matching

Impedance, measured in ohms (Ω), represents the resistance encountered by the amplifier's output when driving a load, such as the subwoofers. Matching the impedance of the subwoofers to the amplifier's specified load impedance is crucial for optimal performance and protection of your equipment.

Series and Parallel Wiring

When connecting two subwoofers to a mono amplifier, you can choose between series or parallel wiring configurations.

* Series Wiring: In this configuration, the subwoofers are connected in a single loop, with the positive terminal of one subwoofer connected to the negative terminal of the other. The total impedance is the sum of the individual impedances.

* Parallel Wiring: In this configuration, the subwoofers are connected with their positive terminals to each other's positive terminals and their negative terminals to each other's negative terminals. The total impedance is lower than the individual impedances.

Choosing the Configuration

The choice between series and parallel wiring depends on the impedance of the subwoofers and the amplifier's load impedance.

* Series Wiring: If the subwoofers have a high impedance, such as 8 Ω or 16 Ω, series wiring may be necessary to increase the total impedance. This ensures the amplifier is not overloaded by a low impedance.

* Parallel Wiring: If the subwoofers have a low impedance, such as 4 Ω or 2 Ω, parallel wiring may be necessary to decrease the total impedance. This ensures the amplifier can deliver sufficient power to the subwoofers.

Safety Precautions

Before connecting subwoofers to a mono amplifier, verify the amplifier's load impedance specifications and the subwoofers' impedance. Never connect subwoofers with a lower impedance than the amplifier's specified load impedance. This can damage the amplifier.

If you want to bridge a 2-channel amp to one channel, it's best to only connect one 4-ohm woofer. The minimum impedance for the bridged (mono) output of a 2-channel amp is usually 4 ohms. Mono subwoofer amps, like the Kenwood KAC-5001PS, are stable down to 2 ohms, allowing you to hook up two 4-ohm subs in parallel.read more >>
