This presents a 2 ohm mono load to the amplifier which may damage most amplifiers.Īn important note about the Flash demos/graphics on this site.

This image shows the DVC driver with both voice coils wired in parallel. Each channel of the amplifier drives a 4 ohm load. The image below shows the DVC speaker wired to both channels of a stereo amplifier. At the bottom, you can see that 2 ohm mono (two 4 ohm speakers bridged) is the same as 1 ohm stereo (four 4 ohm speakers per channel). In the diagrams below, you can see the relative current flow from the amplifier's outputs (indicated by the red arrows) into various loads. This is a lot more common in musical instrument (guitar and bass guitar) speaker cabinets.

Connecting individual woofers in a series configuration is not common in car audio.

This is a series/parallel connection (below). This is especially true when connecting speakers in parallel onto a bridged amplifier.Įnter the impedance of the speakers that are connected in parallel (starting at the top). The impedance can quickly fall below safe levels. You must be careful when paralleling speakers onto an amplifier. The same is done with all of the negative connections. As you can see in the diagram below, all of the positive speaker connections are connected and then connected to the positive terminal of the amplifier. If you have two 4 ohm speakers connected in parallel, the total impedance is 4/2 or 2 ohms. If all speakers have the same impedance, the total impedance is the impedance of a single speaker divided by the total number of speakers. This means that, given the same output voltage, the current demand on the amplifier will be increased. When speakers are connected in parallel, the impedance is reduced. The impedance change with a parallel speaker connection is only slightly more complicated than the series connection. If there were three 4 ohm speakers in series, the total impedance will be 12 ohms. In a series connection, you simply add the individual impedances. If both of the speakers have an impedance of 4 ohms, the total impedance will be 8 ohms. Lastly connect the negative terminal of speaker 'B' to the negative terminal of the amplifier. Then you connect the negative terminal of speaker 'A' to the positive terminal of speaker 'B'.

In a series connection you simply connect the positive terminal of speaker 'A' to positive terminal of the amplifier. This page will explain how the impedance changes when speakers are connected in series. We described series speaker connections on a previous page.

The amp won't produce full power and the system won't produce as much SPL as it would with the correct load but it's also going to allow the amp to operate safely and reliably. The better option is to connect the speakers to present a lighter_than_minimum load. This would get more power from the amp but it's also likely to cost the owner $200+ to repair the amp. The speakers could be connected to present a load that is unsafe (for example, a 1 ohm load for an amp only capable of driving 2 ohms minimum). In those instances, there will be two choices. There will be some speaker/amplifier combinations that will not allow full power to be produced safely. Most people want to connect their speakers in the lowest possible safe load to get the most power from their amplifiers.

This page is for those who don't fully understand how to connect their speakers to their amplifiers to present a safe load to the amplifier. Series, Parallel and Series/Parallel Resistance
