![]() Two DVC drivers with Voice Coils in Series / Parallel One DVC driver with Voice Coils in ParallelĬonnecting the two voice coils of the driver in parallel (+ to +, - to -) will result in the following impedances: Note: Amplifier depicted is for reference only - check the capability of your amplifier before making any connections One DVC driver with Voice Coils in SeriesĬonnecting the two voice coils of the driver in series (+ to -) will result in the following impedances: You will more than likely find that the results will be less than optimal. For more information, please consult our Dual Voice Coil FAQs.Īdditionally, if you have an idea for a wiring configuration and you do not see it here, chances are you should re-think its implementation (in other words, don’t do it). This does not include series connections made between voice coils on the same driver. Please note that when wiring multiple drivers it is recommended that series connections between drivers be avoided at all costs. Fear not, though, for we have compiled wiring diagrams of several configurations for dual voice coil (DVC) drivers. The circuitry of the amp must be able to handle this increase in current at the reduced resistance.With multi-driver sub systems, which often feature dual voice coils (DVC) on each driver, the level of wiring complexity can be enough to turn-off even the most adventurous of car audio do-it-yourselfers. So, each time a Speaker with the same resistance is added to the parallel circuit, the current draw on the amp increases. Parallel Circuits are the simplest to wire because adding a Speaker is as easy as connecting the new Speakers (+) positive lead to the (+) Speaker wires of the other Speakers and the (-) negative lead to the (-) connection of the other Speakers.Īdding additional Speakers is as easy, however, adding Speakers in Parallel causes the overall resistance of the circuit to drop, as resistance drops, the current must increase according to Ohms Law. Parallel Speaker Wiring combines all Speakers (+) positive Speaker leads together, and all (-) negative Speaker leads together. Parallel circuits are the simplest electrical circuit to wire.Īdding Speakers in parallel decreases the overall resistance of the circuit The formular for Series Wiring is: Znet=Z1+Z2+Z3…. However, increasing the resistance to more than 4 ohms of speaker resistance by adding Speakers in Series, will split the amplified audio output from the Amplifier across all the Speakers in the circuit. 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.Ĥ Ohm Speakers (unlike Speakers at 8 ohms of resistance) keep the “overall” resistance on the Amplifier at or near 4 ohms. ![]() Since Series Circuits are “voltage dividers” each Speaker sees a percentage of the amplified output from the Amplifier. Series Circuits are “voltage dividers”, and using Ohms Law, one sees the result as a decrease in amplified voltage audio signal to each Speaker. This allows the Amplifier to run cooler and more efficiently. Therefore the resistance of each Speaker is added together, For advanced installations with Multiple Speakers, Series Speaker wiring can be used to increase the resistance of the “equivalent” or “overall” resistance that the Amplifier sees. ![]() The Amplifier sends an audio signal (+) out through the (+) Speaker output into the first Speaker then the signal is sent from the first Speaker’s (+) and so on until the circuit is complete with the (-) of the last speaker is connected the Amplifier’s (-) connection.Īdding Speakers in series increases the overall resistance of the circuit. 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.Īlthough we discuss here two ways to wiring Speakers – Series and Parallel, we should mention Series/ Parallel Combination, so we have included a diagram showing this configuration. It is also quite common to wire Speakers in a Series/Parallel Combination. There are several ways to wire up Speakers, the most common methods are Series and Parallel which are discussed here.
