Series wiring and parallel wiring To give you an example of how confusing this is, imagine 2 8 ohm speakers. The value is often found printed on the magnet, if you're unsure of what you have. Will it hurt the amp to run it at 12 ohms? 4 Ohm Subwoofer: 4 Ohms; 8 Ohm Subwoofer: 8 Ohms; 12 Ohm Subwoofer: 12 Ohms; Two SVC Drivers with Voice Coils in Parallel. Determine what amplifier to use with your subwoofer system. Since each sub gets a channel, you will also look at the 1 Sub section on the chart. Using the wire striper, strip back the wire jacket (insulation) about 1/8" to 1/4" to expose the wire. Check the amplifier's owners manual for minimum impedance the amplifier will handle before hooking up the speakers. Subwoofer voice coils usually come in 2-ohm, 4-ohm, or 8-ohm impedances. I have a room in my house with 6 in ceiling speakers. You’ve converted an 8-ohm speaker to 4 ohms. Because my friend is buyin my amp off of me and his sub is dual 4 ohm. The formula for finding total impedance of speakers wired in parallel is a little trickier. They show a typical single channel wiring scheme. Voila! It is (Z1 x Z2 x Z3…) / (Z1 + Z2 + Z3…) =Ztotal. The specs only list 6 or 8 ohms. The results will display the correct subwoofer wiring diagram and impedance load to help find a compatible amplifier. It’s a Marantz 6012. Conclusion Wow that sounds repetive. What’s harder is dealing with a parallel circuit. A parallel wiring turns those 2 8 ohm speakers into a system of 4 ohms total. Our subwoofer wiring calculator allows you to figure out how to wire your Dual 1 Ohm, Dual 2 Ohm, and Dual 4 Ohm subwoofers in several different qualities. rather than 2 or 8? Two Single Voice Coil Speakers In Parallel. Dual voice coil subs ensure the flexibility to allow the best connection. To do so, a 1 foot section of positive speaker wire and a 1 foot section of negative speaker wire is cut and prepared. thanks for your help My amp is 4ohm mono stable, so I had a dual 2 ohm wired in series. Because the woofer is a Dual 4 ohm we are going to have to connect the two terminals on the subwoofer. The following diagrams are the most popular wiring configurations when using Dual Voice Coil woofers. Subwoofer Wiring Size. A pair of dvc 4 ohm subs can be wired to 1 ohm. No, a dual four ohm sub can only be wired to 2 or 8 ohms, sorry. I was going to wire 2 in parallel and one in series per channel to get a left and right channel. For a two subwoofer example, wire both dual voice coils in series to present 8 ohms from each sub, then wire the two 8 ohm subs in parallel to bring the total impedance presented to the amplifier to 4 ohms, a common setup when bridging two channel amps. And to don ---- using a "choke" is a complete waste, and obsolete. Understanding a parallel circuit. This is pretty simple, too. Since my amp can’t handle 2 ohms. Since the subwoofers we choose can only be wired at 4 ohms, you would need to find a different set of subwoofers that are suitable for 2 or 8 ohm loads. The total load of the four dual 4-Ohm voice coil subwoofers connected in a parallel/series configuration is 8-Ohms. Select your Woofer Quantity and Woofer Impedance to see available wiring configurations. Dual Voice Coil Wiring Options. For example, if you have three speakers with impedance values of 4 Ohms, 6 Ohms, and 8 Ohms your total impedance wired in series would be 18 Ohms (4+6+8=18). Wire both woofer (+) to the amplifier’s (+), and do the same with the (-) connections. If you are wanting to know how to wire your subs look no further than our wire diagram. They are 8 ohm each. If your system has 1000 Watts RMS or more, you should upgrade to 12-gage speaker wire. But i need to know cause his sub is dual 4ohm. Welcome to the CT Sounds Subwoofer Wiring Wizard. The chart tells us that a 4 ohm dual voice coil wires to 2 ohms or 8 ohms, not 4 ohms. For systems with less than 1000 Watts RMS, 16-gage speaker wire is adequate. Woofer Wiring Wizard. See if they will take it back, and get a pair of the "next level down" series subs in dual four ohms.
