Bridging speakers together
There are a lot of people talking on this topic and it has become very complicated. Wiring of two channels on one speaker is possible but in many ways, it can damage your amplifier. You may be trying to run both the left and right channels on one speaker only. It can be done but method may vary from setup to setup of the amplifier. Now we discuss some methods that people are trying to wire both channels on one speaker and tell you whether it will be good for you or not. Many people tried this by connecting the left and right channels together and then connecting them to the single speaker.

Last Updated: July 1, This article was co-authored by wikiHow Staff. Our trained team of editors and researchers validate articles for accuracy and comprehensiveness. This article has been viewed , times. Learn more The term "bridging sub-woofers" is a bit misleading. The phrase actually refers to wiring the sub-woofers up to a bridged amplifier to produce fuller, deeper bass. This generally leads to a superior sonic experience coming from your home or car stereo system.
Learning the ins and outs of a bridged circuit is important, though, as an improper setup can damage your equipment. Log in Social login does not work in incognito and private browsers.

Locate the specification labels for your system. Your amp should have a label near the speaker output jack that indicates the output power measured in Watts and the minimum impedance measured in Ohms.
Be sure that your use the values for bridged mode, it is usually double the minimum impedance as stereo mode meaning you need a much high impedance to run a bridged system and up to four times the power output. Your sub-woofers should also be labeled with an impedance value in Ohms and a value indicating the maximum power input that they can handle in Watts. Most car stereo amplifiers can do 2 ohms.
Write down these values. You should have at least four different values written down. Calculate the total impedance of all of your speakers. To do this you should add together the speaker impedance number for all of your speakers. You want the impedance to be at least equal to the minimum impedance value of your amp on each channel, but not to exceed 16 Ohms unless your amp is specifically rated for impedance values above 16 Ohms. Where Z is the impedance of a given speaker.
The formula for finding total impedance of speakers wired in parallel is a little trickier. So say you have two speakers with impedances of 6 Ohms and 8 Ohms. This time it would look like this: 1 Multiply the values.
Calculate the power each speaker will receive. This will be based upon the total impedance and the power output of your amplifier.
You do not want to overpower and blow your speakers. Verify that your amp has enough power for your subs. The output power should be stamped near the output jack on your amplifier and measured in Watts. You speakers should also be labeled with a wattage. The output wattage should meet or exceed the sum of all of your speakers.
For example if you have two subs that each pull W, you would want an amp that produces a minimum of W. Ideally you would have an amp that produces more than what is required, this is referred to as "head room" and helps to avoid clipping. Unplug your equipment. Wiring powered devices can be dangerous.
If you are working on a car stereo system you can simply disconnect the battery terminals. Method 2. Get a roll of stereo wire. You will need this wire to make the connections from your amplifier to your sub-woofers. See How to Wire Speakers for tips on connecting speaker wires. Wire the amplifier to the subwoofers.
Check to see which two terminals are used for bridge mode on your amplifier. This will be labeled on the amp. Wire the first sub by running a wire from the positive terminal on the amp to the positive bridge terminal on the sub.
Wire the second subwoofer to the first subwoofer. If you wish to wire them in series, run a single wire from the negative terminal of the first sub to the positive terminal of the second sub. If you wish to wire them in parallel you will run two wires between the two subs. The firs will connect the two positive terminals, and the second will connect the two negative terminals. Complete the circuit. Connect the wire from the second sub's negative terminal to the negative bridge terminal on the amp.
This will complete the circuit whether you are wiring in parallel or in series. Method 3. Wire the amplifier to the first subwoofer. The wiring here will be similar to wiring a single voice coil SVC sub-woofer. The difference to remember is that dual voice coil DVC subs have two coils, and thus four input terminals.
Two of them are positive and two are negative. Choose one of the positive terminals and connect it to the positive bridged terminal of the amp. Connect the two coils. Just like wiring two separate speakers, the two coils within your DVC can be wired in series increasing the sub's impedance or in parallel decreasing the sub's impedance.
If you are wiring the coils in series then run a wire from the positive terminal of the first coil the one wired to the amp to the negative terminal of the second coil and from the negative terminal of the first coil to the positive terminal of the second. If you are wiring the coils in parallel then run a wire from the first positive terminal to the second positive terminal and a wire from the first negative terminal to the second negative terminal.
Again, you have the series verses parallel debate. If you choose to wire the subs in series, connect the negative end of the second coil in the first sub to the positive end of the first coil in the second sub these circuits can get complicated fast. Next, connect the negative end of the first coil to the positive end of the second coil. Finally connect the negative end of the second coil to the negative bridged terminal on the amp.
If wiring in parallel, connect the negative end of the first sub's second coil to the negative end of the second sub's second coil. Connect the positive end of the first sub's first coil to the positive end of the second sub's first coil. Connect the second sub's coils. Follow the same guidelines as when you connected the first sub's coils.
Now comes the easy part. Regardless of which combinations of series and parallels you chose above to get the proper impedance and power distribution in your system, closing the circuit will be one easy step.
Run a wire to connect the negative terminal of the second coil in your second sub to the negative bridged terminal of the amp. Listen for inconsistencies. Power up your system and test it out.
If the bass and sub-bass are quiet or not present at all, something is mis-wired. How do I stop a new stereo amp from locking on protection mode with the first hard hit on bass? Make sure you read the manual, and if that doesn't work, then contact the company from where you got that stereo.
Yes No. Not Helpful 0 Helpful 3. Use the positive from channel 1 and the negative from channel 2 to one of your subs. Then use the positive from channel 3 and the negative from channel 4 to your other sub. Not Helpful 1 Helpful 4.
How do I bridge a woofer when I have one single voice coil and one double voice coil? It depends on the amplifier. If it is capable of driving powering low impedance loads, then it can be done.
If you end up putting the subs in series, then you won't get much volume out of the system.
Amplifier Buying Guide
AudioControl Director and Architect series amplifiers have the capability to bridge amplifier channels together to deliver more power to your speakers. Bridging amplifier channels combines a stereo pair of channels into a single mono channel. All stereo amplifier channel pairs on Director and Architect amps are capable of being bridged. This means that a bridged amp driving an 8 ohm speaker is actually operating into a 4 ohm load. Also, make sure your speakers are rated to handle the increased power that is provided by bridging. The Architect Model bridged power rating is watts.

The ohm is a measurement of the electric resistance between two points. In a speaker, the ohm is a bad thing. The lower the ohms the less energy it takes to drive the speaker. The less energy, the more you get out of your amps. An 8 ohm speaker requires more amperage to run than a 4 ohm speaker. You need to know the ohms of all of your speakers if you want to calculate the load your amp is taking and to compensate for it. In a car audio you should always run your equipment at the lowest possible Ohm load that an amplifier, head unit or speaker can safely handle.
4 Ohm Sub To 2 Ohm Amp
In order to define your needs, you have to set the results you want to obtain from your system. Just answer the questions a Car Stereo Specialty Store would ask you: What kind of music do you listen to? Do you need great amounts of low frequency bass output? Do you plan to install a subwoofer? Do you listen to music at loud volume?
Wiring Subwoofers & Speakers To Change Ohm’s
It is basically a 4 channel amp that puts out 20 watts at 4 ohms plus 2 channels for a subwoofer with added power. Average Rating: 0. There is no harm in running a higher ohm cab than the amp. Replacing a driver on your 2 x 10" combo? We've got you covered.
Remove a Bridge from your Sonos system
Let me help you understand what bridging is, why it matters, and how to bridge your amp. A 4 channel car amplifier bridged to 2 channels. Bridging is a special feature in car amplifiers which lets you get the maximum amount of power they can produce by using a built-in channel-sharing design. It means using 2 amplifier channels working together to drive a speaker or a set of speakers with by using the power that normally is split between 2 separate amplifier channels. For example, I have owned many car amplifiers and normally used 4 or 5-channel amplifiers. I used 2 channels, in bridged mode to drive a single subwoofer or a pair of subwoofers in the trunk. This meant having more power available at my disposal and more flexibility even if I changed my speaker setup later.
How To Wire/Connect 4 Speakers To A 2 Channel Amp Diagram?
There are several ways to wire up Speakers, the most common methods are Series and Parallel which are discussed here. Wiring up Speakers correctly to provide the best possible sound, requires some knowledge of Loading, Phase, and Impedance, while understanding Ohms Law will help you to connect your speakers properly. This allows the Amplifier to run cooler and more efficiently. It is often assumed the Amplifier is producing less output, but it still produces the same output, because each Speaker only gets a percentage of the overall power.
SERIES & PARALLEL SPEAKER WIRING
The meaning of bridging is to link one thing with another. This bridging of speakers refers to the combination of speakers with each other with the help of a device known as an amplifier. In this article, we will discuss the bridging of speakers. The first reason that leads to the bridging of speakers is that you need to cover a big area so that is why you need to bridge the speakers together. For example a large room with a high roof in which you cannot hear the sound properly. The second reason that is a cause of the bridging of speakers is that you are having a party and you need a big music system for that this reason also urges to bridge the speakers together.
Multiple electronic amplifiers can be connected such that they drive a single floating load bridge or a single common load parallel , to increase the amount of power available in different situations. This is commonly encountered in audio applications. Bridged or paralleled modes of working, normally involving audio power amplifiers, are methods of combining the output of two identical amplifiers to provide, what is in effect, a mono amplifier. Combining more than two amplifiers can be effected using the basic principles described, including the possibility of bridge and parallel modes in combination. Two identical amplifiers are most often encountered in a common case, with a common power supply, and would normally be regarded as a stereo amplifier. Any conventional stereo amplifier can be operated in bridge or parallel mode provided that the common loudspeaker terminals normally black are connected and common to the ground rail within the amplifier. Some two channel amplifiers, or stereo amplifiers, have the built in facility to operate in bridge mode by operating a switch and observing the input and output connections detailed on the back panel or in the manual.
