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