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