Wiring 2 subs to mono amp1/8/2023 This will result in a 2 ohm final load on the amplifier. Therefore you would connect your DVC-2 woofers in series for a 4 ohm load per woofer and connect one woofer with it's remaining + and - to each set of terminals. the stipulation is making sure the subs are the right ohm load for the amp and that they are wired correctly. The terminals are in parallel inside the amplifier. the answer is definitely yes, and it typically just splits the wattage 50-50 between the two subs. And even though they provide a diagram for the amp, I don't get it as it makes zero sense to me. It's not the sub wiring itself that is confusing to me as I can follow a wiring diagram easily enough. Would be much simpler to me if there was one pos and one neg instead of 2 pos and 2 neg. Or should I wire it as option 2 or 3 at the bottom of this page What I don't get or understand is the 4 speaker terminals on the amp itself. I/O Channel Count: 2x2 Built-in 8.5 W mono amplifier to drive a local. If that is correct then I would run wires from each speaker and use the 4 terminals on the amp. Integrated 3 x 2 HDMI switcher for local video switching 8x AEC processors. When you wire dual voice coils and multiple subs together, the resulting total impedance is not always simple to figure out or practical to use. If I understand his reply I can run each speaker at 4 ohms and it will automatically run internally at 2 ohms. Whether you need to use a series wiring configuration, parallel wiring, or a mix of both, our diagrams will show you exactly the best way to wire your speakers, without using confusing technical terms. 5 Stable Amplifier) (3) Dual 2 Subwoofers. I believe you are correct as the Prez of sundown audio says the amps internals are in parallel. Connecting the two voice coils of each sub in parallel (+ to +, to -) and the subs themselves in parallel will score the following impedances: (3) Dual 4 Subwoofers. My apologies and if a mod can move this please do. Seems my subs will be very overpowered but with a very clean signal before I turn the knob back down.Ĭlick to expand.Yeah, I guess i should have put it in the appropriate section. In this case, connect the 4-ohm speaker to one channel of your amp and. For example, an amp might run at 550 watts with subs wired at 4 ohms, and 1100 watts with subs wired at 2 ohms. Consult your amp manual for specific directions on your particular model. You must also flip the amp into bridge mono mode, using dip switches on the back of your amp. Usually you connect a banana plug to the middle two banana outputs. The speaker with a lower impedance should be connected to the amplifier. The impedance rating of a subwoofer represents the load an amplifier will sense on its output. Connecting speakers to an amp in bridge mono mode is different from stereo mode. For example, if one subwoofer has an impedance of four ohms and the other is two ohms. I know wiring it up at 2 ohms might make for a harder hit but the reality is my subs are rated at 250-400 rms and the amp does 1200 at 2 ohms. If you have two subwoofers with different impedances, the lower impedance should be connected to the amplifier. Here is a link to the user manual which might as well be printed in french for me. My preference would be to wire it up at 4 ohms on each speaker Can I do that or do I have to connect both subs and run them at 2 ohms. It's a mono amp and has 4 slots for speakers. What I need to know is connecting the subs to the amp. It is all installed and powered as far as door and rear deck speakers are concerned. Doing it all on my own with zero experience. I have installed 4 new speakers, Deck, eq, sub box, subs. Given the rated output impedance of the DX7s to coax is 100 ohms (unbalanced) and referencing the linked schematics, what would be the best resistance values to use to ensure that the summing function does not create unacceptable crosstalk in the signals to the amp?Īlso, there has been mention of inverting one channel on some forums, which actually does not make sense to me, as it seems that would cause cancellation issues.įinally, if anyone knows of a competent and inexpensive solution for sale somewhere, I'd be grateful for that info also.Ok, I like to do things myself but find this one is a wee bit challenging. I am certainly capable of DIYing a few resistors to a Y-cable or making a summing adapter box, but given the output impedance of the DX7s and the worry of this causing substantial crosstalk, I'm not sure if this is really the best option. There is a lot of ignorant chatter on the teh interwebz about this, and some good stuff too, but I need illumination from those that are more technically adept on how BEST to approach this. I'm wanting to plug an Elac Debut S10EQ subwoofer in for a bit of low end-fill, but I have no mono outputs, and the sub only accepts a single line-level input. I am using my Topping DX7s to directly feed my 2 channel system amp when the HPs are not plugged into the front. This should be easy, but it seems that it's not.
