Subwoofer wiring diagrams
How to hook up your subs for powerful bass
In this article, we'll help you find the best way to connect your subs to your amp. We begin with some basic – and important – subwoofer and amplifier terms. But if you want, you can skip straight to the wiring diagrams.
There are many ways to wire subwoofers and amplifiers together. The ideal setup is when subs and amps match their impedance and power capabilities to optimize performance.
Power with care
The diagrams show wiring configurations for amplifiers and subwoofers that have already been matched for power capabilities. You should never connect subs to an amp that could give them more than their total watts RMS power ratings — that could damage the subs or the amp. See How to match subs and amps for further guidance.
Here's an example diagram for connecting two 4-ohm DVC subs to a mono-channel amplifier:

Important subwoofer wiring terms
The diagrams are below, but first let's explain a few important terms.
SVC
A single voice coil sub with two wiring terminal posts, one marked positive and the other marked negative.
DVC
A dual voice coil sub with four wiring terminal posts, two positive terminals and two negative terminals. This gives you more options for wiring the sub in different situations.
Ohms
The impedance load, or resistance against the amplifier's output signal, of a subwoofer coil. Subwoofer voice coils usually come in 2-ohm, 4-ohm, or 8-ohm impedances. The value is often found printed on the magnet, if you're unsure of what you have.
Series and parallel wiring
These terms refer to two ways of routing the speaker wires to properly manage the overall impedance load. Whether you need to use a series wiring configuration, parallel wiring, or a mix of both, our diagrams will show you exactly the best way to wire your speakers, without using confusing technical terms.
When you wire dual voice coils and multiple subs together, the resulting total impedance is not always simple to figure out or practical to use. In the example diagram above, the voice coils of each sub are wired together in series, while the two subs themselves are wired together in parallel.
Amplifier output
An amplifier will put out more power through a low-impedance sub than it will through a high-impedance sub. But a lower impedance also means more stress on the amp. Some amplifiers (marked “low-imp” in the links below) can even drive a 1-ohm load safely, and achieve maximum output. Refer to your amp manufacturer or owner's manual to determine whether or not yours can handle a low-impedance load.
Bridged mode
Bridging an amp combines two amplifier channels into one, to get more power. The disadvantage of bridging is that bridged channels can't drive impedance loads as low as they can when unbridged. The proper way to bridge the amp is usually indicated at the amp's speaker wire terminals. For more information, read our How to bridge an amplifier article.
Wire
All the wires depicted in the Subwoofer Wiring Diagrams are speaker wires. For wiring subwoofers, we recommend using wires of 12- to 16-gauge in size.

Find the right wiring diagram
Now, let's get those subs hooked up! All of our wiring diagrams are listed below. It's a long list. To make it easier to find the one you need, select which type of amplifier you have:
From there, select the diagram for the number and type of subs you have. Depending on your gear, there might be more than one way to safely wire the subs.
A note about multi-channel amplifiers
5-channel amplifiers are a popular way to get "full system" power in one box — four channels to drive your four speakers, plus a fifth, higher-powered channel for your subwoofer. 6- and 8-channel amps are similar and offer even more flexibility. When it comes to connecting subwoofers to these amps, keep it simple:
- If you're connecting your sub(s) to the subwoofer channel, treat it like a mono-channel amplifier.
- If you're bridging two channels of your amp, simply treat it as a bridged 4-channel amp.

I have 2 kicker comp r subs.. 1000 watt max and 500rms each. I have an 800 watt amp powering them right now. But wanting more power. Can't really find a reasonably priced 1000 watt amp. My question is could I use a 1200 watt amp?

Hello! i recently acquired two old school JL audio subs and one is a 4 ohm and the other is a 6 ohm. They are 12w3v2-d4 and 12w3v2-d6 subs. Would i somehow be able to use these together? thanks in advance

Hi There! I have an Targa TA 4100.4 amp and want to match it with a MBQ PB12 150W DVC-2 8" Active Subwoofer. Will it work? Kind regards

Love what you guys do here longtime customer! My question is could a Kicker 46CXA1200.1 power up two solo baric Kicker 44TL7S102 in their respective boxes? Of course the big three would be needed

Hello! Since I see others are asking about specific scenarios, I will too! What would be my best wiring option for my 2-2ohm dvc subs & monoblock amp combo... 2011 Mercedes c300 Sealed dual 12" box 2-Rockford Fosgate 12" P2D212 1- Memphis 16-PRD1000.1 Also what size inline fuse should be used with this setup? I have a 100A & a 200A & not sure which is appropriate.

Hey Buck, Afternoon and hope you and yours are all safe. I have 2 Scar SVR-D4s and I have a few amps that I can wire to them. To you, for best, most crisp sound, would you wire them to an amp at 1200w RMS at 4 ohms and have them wired to match that impedance, or keep current configuration and have them wired at 1 ohm, connected to 600w at 1 ohm. 1200w is A/B and 600 is D. Thank you in advance.

I have 2 mojo7 12" subs that can handle 1 and 2 ohms. 1500rms 3000peak. If I obtain a 1 ohm stable amp, but I want to wire the subs up as 2 ohms, how can I do that? Or is that possible. Specs say its a triple voice coil, but all i can find diagrams for are dvc. Heard 2 ohm loads are cleaner sound. So would i also need to look for a 4500w amp 1 ohm stable to fully power those two subs?
