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