How to Link Two Speakers to a Single Amplifier?

This guide covers both the theory and practical steps on how to connect two speakers. Connecting two speakers in parallel or series to your amplifier is useful if you don’t need to turn each speaker on or off individually or control their volumes separately. If you do need individual control, a speaker selector switch is recommended, and you should check out articles on connecting multiple speakers, wiring four speakers, or using speaker selector switches.

Many people get confused about stereo amplifiers, which have two built-in amplifiers in one unit. We’re not talking about connecting two speakers to a stereo amp (one speaker per amplifier, left and right), but rather connecting four speakers to a stereo amp (two speakers per amplifier). For simplicity, when discussing amplifiers here, we mean either the left or right amplifier only.

Connecting two speakers to one amplifier without individual switching or volume control is useful if you have a large living area with four ceiling speakers, want to cover a large backyard with four speakers, or have any situation where two speakers aren’t enough. There are two basic ways to connect two speakers: in series or parallel.

Should two speakers be connected in series or parallel?

Whether two speakers should be connected in series or parallel to one amplifier largely depends on their impedance.

Connecting 2 speakers with 8 ohms:

The speaker impedance is usually marked on the back of the speaker or the speaker box, typically as 4 ohms, 6 ohms, or 8 ohms. If it’s not visible, check the paperwork that came with the speaker or look up the specifications online. The symbol Ω often represents “ohms.”

If both speakers are 8 ohms or more, they can typically be wired in parallel. If the speakers are less than 8 ohms, it is safer to wire them in series.

How to connect several speakers in parallel or series to a single output?

Connecting Multiple Speakers in Series:

Prepare the Wires: Strip the insulation from the wire to expose the bare wire.
First Speaker Connection: Connect one wire to the positive terminal of the output, then to the positive terminal of the first speaker.
Link Speakers: Connect the negative terminal of the first speaker to the positive terminal of the second speaker.
Final Connection: Connect the negative terminal of the last speaker to the negative terminal of the output.

Connecting Multiple Speakers in Parallel:

Positive Terminals: Connect a wire from the positive terminal of each speaker to the positive terminal of the output.
Negative Terminals: Connect a wire from the negative terminal of each speaker to the negative terminal of the output.

What occurs when two speakers are connected to a single channel?

When two speakers are connected to one channel, the total impedance (Ohms load) changes depending on the connection type, affecting the current flow and the amplifier’s workload.

Parallel Connection: The total impedance is lower, calculated by dividing the speaker impedance by the number of speakers. This increases current flow if the amplifier can supply it.
Series Connection: The total impedance is higher, calculated by adding the impedances together. This reduces current flow.

If the impedance is too low, the amplifier may overheat and get damaged. Higher impedance is safer, but the amplifier will produce less power, with each speaker receiving less wattage.

Explain how power distribution works for speakers connected in parallel or series?

When connecting two speakers to a single output channel, it’s important to understand that they will share the available power. Here are some key points to remember:

Parallel Connection:

Speakers share the total output power based on the combined speaker load. For instance, connecting two 4-ohm speakers in parallel results in a total load of 2 ohms. Each speaker receives half of the rated power output at 2 ohms.

Series Connection:

Speakers in series receive less overall power because the total power distributed is lower compared to parallel connections. For example, two 4-ohm speakers in series create an 8-ohm total load. The power output at 8 ohms is half that of 4 ohms (according to Ohm’s Law for power), with each speaker receiving half of that power.

When you connect two speakers to one output channel, it involves a compromise that affects the power distribution. Devices like car stereos, home AV receivers, and amplifiers are typically designed with one speaker per channel in mind.

When should you opt for a parallel connection versus a series connection for speakers?

Single cone speakers lack an additional tweeter found in two-way stereo pairs or car audio coaxial speakers. Although this might not initially seem significant, two-way speakers always incorporate at least a tweeter crossover, and often a woofer crossover too.

Speaker crossovers, which use inductors and capacitors, impact sound quality when connected in series, as I’ll explain in the next section.

Here are some guidelines for choosing between series and parallel speaker wiring:

If your radio, amp, or AV receiver can handle the ohm load of two speakers in parallel, that’s the preferable option. Each speaker will receive more power compared to series wiring.
When parallel wiring isn’t feasible or you’re uncertain, connecting speakers in series is a safe choice. They won’t get as much power, but the output electronics won’t be harmed.
Connecting two-way or three-way speakers in series will produce sound, but the sound quality may suffer, as I’ll detail further in the next section.
If sound quality isn’t critical and your amplifier or stereo can’t support the ohm load of speakers in parallel, series wiring is generally acceptable.

Why two- or three-way speakers have inferior audio in a series?

Connecting two- or three-way speakers in series often results in poorer audio quality because it disrupts the intended operation of their crossover networks. Here’s why:

1. Crossover Shift:

Impedance Sensitivity: Crossovers are designed to work with a specific speaker impedance.
Impedance Increase: When speakers are connected in series, the overall impedance increases (e.g., two 4-ohm speakers in series become 8 ohms).
Frequency Alteration: This increase in impedance causes the crossover frequencies to shift, resulting in the wrong frequencies being sent to the tweeter and woofer. For example, a crossover designed to filter out certain frequencies might let through unwanted midrange frequencies, causing distortion.

2. Tweeter and Capacitor Issues:

Impedance Doubling: Connecting a tweeter and its capacitor crossover in series with another similar setup doubles the impedance.
Lower Crossover Frequency: The crossover frequency decreases significantly, allowing lower frequencies to reach the tweeter, which can cause muddiness and distortion in the sound.

3. Woofer and Inductor Problems:

Inductor Sensitivity: Woofers use inductors in their crossovers to filter out high frequencies.
Series Connection Effect: When woofers are connected in series, the inductance changes, affecting the woofer’s frequency response.
Imbalanced Sound: This can result in an imbalance, with the woofer either handling frequencies it shouldn’t or not performing well at its intended frequencies.

How to connect two 2-way speakers in parallel to get fantastic sound AND eliminate Ohm’s law?

An example of a speaker volume control with an impedance adapter connected to a 2-channel amp: This adapter allows two 8-ohm speakers wired in parallel (totaling 4 ohms) to appear as one 8-ohm speaker to the source.

It ensures optimal sound quality and correct load impedance by using small transformers to match input and output impedance. Some models can also accommodate 4-ohm speakers with an 8-ohm amp. These adapters are useful for adding extra speakers, such as in a backyard or pool area, via a speaker selector switch.

Tools and Materials Required for Splitting Speaker Wire

Essential Tools:

Step-by-Step Guide to Splitting Speaker Wire

Preparing the Wire:

Start by ensuring the wire is disconnected from any power source. Lay out the wire on a flat surface.

Cutting the Wire:

Use wire cutters to cut the wire at the desired split point. Ensure a clean cut to avoid frayed ends.

Stripping the Insulation:

With wire strippers, carefully remove the insulation from the ends of the wire, exposing about half an inch of bare wire.

Connecting the Wires:

Twist the exposed wires together if connecting multiple wires, or attach connectors to each end. For a more secure connection, solder the wires together.

Insulating the Connection:

Use electrical tape or heat shrink tubing to insulate and safeguard the connection.

Is it OK to splice speaker wire?

Despite companies promoting wire “cookers” and break-in services, this is a myth aimed at making money. Audio experts have found that properly spliced and soldered wires do not alter or degrade the sound quality of speakers.

Can I Cut Speaker Wire in Half?

Yes, you can cut speaker wire in half. When rearranging your speakers and needing to shorten the wires, ensure the wires are not connected to any power source or device. Once disconnected, you can use pliers-style wire cutters, scissors, or a knife to make the cut.

Does Thicker Speaker Wire Sound Better?

The thickness of speaker wire needed is based on the system’s electrical load to achieve the best sound quality. However, a thinner wire works just as well over shorter distances. If the wire only needs to cover a few feet, a lower gauge wire will be sufficient.

Does Speaker Wire Length Affect Sound Quality?

Yes, speaker wire length can impact sound quality. Resistance starts to affect performance when it exceeds 5% of the speaker’s impedance. This resistance is influenced by the wire’s length and thickness. Shorter wires have less resistance and, therefore, less impact on sound quality.

What Gauge is Best for Speaker Wire?

Choosing the right gauge for speaker wire depends on your speakers and their distance from the receiver. For most home theater systems, 16-gauge wire is typically sufficient. However, if your speakers are more than 50 feet away from the receiver, using 14-gauge wire is a good option to ensure optimal performance.

Which is Thicker: 12 or 14 Gauge Speaker Wire?

12 gauge speaker wire is thicker than 14 gauge wire. The 12 gauge wire has a minimum thickness of 0.098 inches, while the 14 gauge wire has a minimum thickness of 0.070 inches. This makes 12 gauge wire about 40% heavier than 14 gauge wire. The 12 gauge is designed to handle dynamic pressure, whereas the 14 gauge is suited for static pressure.

What Happens if You Mix Up Speaker Wires?

If you mix up speaker wires, the signal may cut out due to a phenomenon known as inverse polarity. This occurs when one wire carries a positive signal while the other carries a negative one, leading to silence. It’s crucial to connect the correct wires to each port and terminal to ensure proper audio function.
