How to Wire Two Dual 2 ohm Subwoofers to a 2 ohm Final Impedance
Can you hook up 2 subs to a monoblock amp?
One Dual Voice Coil Speaker in Series. Connecting the two voice coils of the driver in series (+ to -) will result in the following impedances: Dual–8 Ohm Subwoofer: 16 Ohms; Dual-6 Ohm Subwoofer: 12 Ohms; Dual–4 Ohm Subwoofer : 8 Ohms; Dual–2 Ohm Subwoofer: 4 Ohms; Dual– Ohm Subwoofer: 3 Ohms. yes. you may have the possibility of "bridging" this is essentially what you are doing, some amps have a switch for it, but i think only if they can also run in stereo. actually this is the best way to power subs. run two wires from the same output on your amp and one to each sub. you will have 2 positives wires. By wiring the two subs in parallel (see the diagram) you'll show a 2-ohm impedance to the amp. Mono amps are built for just this kind of situation, so you'll get maximum power output from your amp investment. Check the diagram below for how to hook it up. SVC subs. Two 4-ohm SVC subs — a great place to use a mono.
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.

Either way will technically solve the impedance issue, but your may still some interesting acoustic issues with polarity when you have speakers facing each other in close proximity — but that is not my area of expertise. As stated earlier a speaker load is not purely resistive, but a sum of resistance of wire and a reactance of coils and capacitors. This will give a total load impedance of 10 ohms on each amp — which is fine. Yes is mono and the second terminal isnt for a second channel only so you have more room to connect wires.

Thanks for helping us achieve our goal of helping everyone on the planet learn how to do anything! 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.
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.
can you hook up 2 subs to a monoblock amp? | Yahoo Answers
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: 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 Can You Hook Up Two Subs To A Monoblock Amp 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. Wiring powered devices can be dangerous. If you are working on a car stereo system you can simply disconnect the battery terminals.
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. 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 read more or in series.
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.
However, in most speaker boxes, the woofer takes most of the power. Audio Home Audio In other languages: Wire the first sub by running a wire from the positive terminal on the amp to the positive bridge terminal on the sub. So a woofer's impedance might be rated at 8 Ohms but the actual measured resistance might be 6 Ohms.
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 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. 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 Can You Hook Up Two Subs To A Monoblock Amp 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. 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.

Make sure you read the manual, and if that doesn't work, then contact the company from where you got that stereo. Not Helpful 0 Helpful 2. How do I bridge a 4 channel amp with 2 SVC subs and use all 4 channels?
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 3. 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. If the dual VC was 2x 4 ohm, that would give 2 ohm; if the SV is 4 ohm, you add the 2 to get 6 ohm.

Answer this question Flag as I bridged the same terminals on the voice coils. Instead of going from one to two I went from 1st positive to 1st negative. Include your email address to get a message when this question is answered.
