Wiring 2 Subs To Mono Amp: 2 Simple Ways For Success

When you are finding out the ways to wire 2 subs to a Mono Amp to effectively improve your audio quality. So, in this article, we’re going to walk you through this step-by-step guide, making it straightforward to understand. Let’s get started!

What is a Mono Amp?

A Mono Amp or A Mono Amplifier, short for the monophonic amplifier, is a kind of amplifier designed to power a single audio channel. It’s particularly popular in-car audio systems to drive subwoofers due to its ability to deliver high power to get those beats thumping.

Wiring 2 Subs To A Mono Amplifier: Step-by-Step Guide

Here we give you a detailed guide to wire 2 Subs to your mono amplifier:

Method 1: Parallel connection

First, you can create a parallel connection that involves wiring both subwoofers directly to the mono amplifier. Here are detailed steps:

Step 1: Identify the terminals

In the first step, you need to identify the positive and negative terminals on both your subwoofers and your mono amp. Normally, you can see the positive terminal is typically red or marked with a “+”, while the negative terminal is typically black or marked with a “-”.

Step 2: Prepare your wires

Next, you measure the distance between your subwoofers and your mono amp. Then, cut 4 lengths of speaker wire that will comfortably reach.

Step 3: Connect the subs to the amp

In this step, you take the first length of the speaker wire and connect one end to the positive terminal of the first subwoofer and the other end to the positive one of your mono amplifier. After that, you repeat this process with another length of wire, this time connecting the negative terminal of the first subwoofer to the negative one of your mono amplifier.

Step 4: Complete the parallel circuit

Lastly, you repeat the above step with the second subwoofer. Now, you should have both subwoofers wired in parallel to your mono amplifier. This effectively combines the power of the two subs but halves the overall resistance (impedance).

Method 2: Series bridged connection

In this method, you will create a series bridged connection that involves wiring one subwoofer to the amp, then bridging the connection with the second subwoofer. Here’s how to do it:

Step 1: Identify the terminals

As with the parallel connection, the first step is identifying the positive and negative terminals on your subwoofers and mono amp.

Step 2: Prepare your wires

Next, you measure the distance between your subwoofers and your mono amp and cut 3 lengths of speaker wire that will comfortably reach.

Step 3: Connect the first sub to the amp

In this step, you take the first length of the speaker wire and connect one end to the positive terminal of the first subwoofer and the other end to the positive one of your mono amp. Afterward, you take the second length of the speaker wire and connect one end to the negative terminal of the second subwoofer and the other end to the negative one of your mono amp.

Step 4: Bridge the connection

After you’ve finished the above step, you continute to take the final length of the speaker wire and connect one end to the negative terminal of the first subwoofer, and the other end to the positive one of the second subwoofer. So, this was a “bridge” between the two subs.

How To Wire 2 SVC 4 Ohm Subs To Mono Amplifier

Single Voice Coil (SVC) 4 Ohm subs tasks are simpler than dual voice coil subs in terms of wiring. Here’s how to do it:

Step 1: Identify the terminals

First, you need to find the positive (+) and negative (-) terminals on both your SVC 4 Ohm subwoofers and your mono amp.

Step 2: Prepare your wires

In this step, you should measure the distance between your subwoofers and your amp. After that, you cut 4 lengths of speaker wire that can comfortably reach.

Step 3: Connect the subs to the amp

After you’ve finished cutting, you take the first length of the speaker wire. And attach one end to the positive terminal of the first subwoofer and the other end to the positive one of your mono amp. Repeat this with another wire, this time connecting the negative terminal of the first subwoofer to the negative one of your amp.

Step 4: Complete the parallel circuit

In this final step, you repeat the above step with the second subwoofer. You’ve now wired both SVC 4 Ohm subs in parallel to your mono amp. When you do this, you created a parallel circuit and cuts the total impedance in half, resulting in a 2-ohm load on the amp.

How To Wire 2 Dual 2 Ohm Subs To 1 Ohm

Wiring two dual 2 Ohm subs to 1 Ohm is a bit more complex but completely manageable. Here’s how to do it:

Step 1: Identify the terminals:

First, you always need to identify the positive (+) and negative (-) terminals on both your dual 2 Ohm subwoofers and your mono amp. Remember, dual voice coil subs have two sets of terminals.

Step 2: Prepare your wires

In the next step, you should measure the distance between your subwoofers and your amp. After that, you cut 8 lengths of speaker wire that can comfortably reach.

Step 3: Connect the voice coils

For each subwoofer, connect the positive terminal of one voice coil to the positive one of the other voice coil using a length of speaker wire. Do the same for the negative terminals. When you do this, you effectively made each dual 2 Ohm sub act like a single 1 Ohm sub.

Step 4: Connect the subs to the amp

Lastly, just like the SVC 4 Ohm subs, you still connect the positive terminals of the subs to the positive terminal of your mono amp, and connect the negative terminals likewise. So, this will result in a 1 Ohm load on the amp, perfect for mono amps designed for low impedance.

How To Wire 2 Dual Ohm Subs Down To 2 Ohms

2 Dual 2 Ohms

To wire two dual 2 Ohm subwoofers down to a total of 2 Ohms, you will wire each subwoofer in series, and then wire the subwoofers to the amplifier in parallel. Here are the steps:

Step 1: Identify the terminals

Like the above guide, first, you need to find both terminals. Remember, dual voice coil subs have two sets of terminals.

Step 2: Prepare your wires

You should measure the distance between your subwoofers and your amplifier. Cut 8 lengths of speaker wire that can comfortably reach.

Step 3: Wire each sub in series

Next, for each subwoofer, connect the positive terminal of one voice coil to the negative one of the second voice coil using a piece of speaker wire. And you do the same for the other subwoofer.

Step 4: Wire the subs in parallel

Now connect the remaining positive terminals of both subwoofers to the positive terminal of your amplifier. In the process, you do the same for the remaining negative terminals. So, this effectively wires your subs in parallel and results in a 2-ohm load on the amplifier.

2 Dual 4 Ohms

The process for wiring two dual 4 Ohm subs down to 2 Ohms is almost identical to the above process:

Step 1: Identify the terminals

In the first step, you still need to identify the positive (+) and negative (-) terminals on both your dual 4 Ohm subwoofers and your amplifier.

Step 2: Prepare your wires

Next, you need to measure the distance between your subwoofers and your amplifier. And cut 8 lengths of speaker wire that can comfortably reach.

Step 3: Wire each sub in series

For each subwoofer, connect the positive terminal of one voice coil to the negative one of the second voice coil using a piece of speaker wire. And you do the same for the other subwoofer.

Step 4: Wire the subs in parallel

Lastly, you connect the remaining positive terminals of both subwoofers to the positive terminal of your amplifier. Do the same for the remaining negative terminals. If you follow this process, this will help effectively wire your subs in parallel and result in a 2-ohm load on the amplifier.

Conclusion

Wiring 2 subs to a mono amp is a simple process when you understand the principles of impedance and parallel and series circuits. Hopefully, this guide will help you to optimize your car’s audio system for the best sound experience. Remember, safety first. If you feel uncomfortable or unsure, please seek professional help.
