That would yeild a 4 ohm load
If it's svc you can't. if it's dvc you can, just connect the + and the - of the voice coils, and then connect the remaining to as normal, + to +, - to -
There are a lot of possibilities here, especially since your question is worded exactly right.I'm taking it you have 4 12" speakers, each of which have Dual Voice Coils (2 Ohms each). You want to wire them together and see what ohm load you have.Ok, there's multiple ways to wire this up. Series, Parallel, and Series/Parallel combo.Wiring these speakers in series can give you either a 4 ohm load, or a 16 ohm load. 4 ohms if each speaker by itself (having DVC) is wired in parallel and 16 ohms if each speaker by itself is wired in series.Wiring these speakers in parallel can give you either a .25 ohm load, or a 1 ohm load. Again .25 ohms if each speaker by itself (having DVC) is wired in parallel and 1 ohms if each speaker by itself is wired in series.Wiring these in a series/parallel configuration can give you tons of different wiring options and ohm loads. In your case .75, 1, 3.2, 4 ohm loads.So your best option would to be wire your speakers up in series, with each speaker wired in parallel to itself. This way you'll get a 4 ohm load, if done properly. Make sure your amp can run a 4 ohm load too.
take a 2 ohm bridge into 1 ohm
You can, but you may damage your amp. If you wire them in parallel (both wires from each connected to the amp) then you will have an effective resistance less than 2 ohms. If you wire them in series then you will have an effective resistance of 6 ohms. Resistance that is too low draws more power than the output is rated for. Resistance that is too high reduces the volume and may distort the sound.
Because it has a Dual Voice Coil (DVC) which gives you more wiring options, eg. dual 2 ohm coils that let you wire in parallel for 1 ohm final, or in series for 4 ohm final load. You MUST use both of them for proper operation of you risk damaging the sub.
Two 8 ohm speakers in parallel is 4 ohms, and the power will be split between them. However, unless the amplifier is rated for 4 ohm operation, you will not get the same total power out of the amplifer as you would with an 8 ohm load.
the impedance of a speaker is a characteristic that is has. A 4 ohm speaker will always have a 4 ohm impedance and it cannot be changed. If 2 speakers of 4 ohm impedance are wired in parallel, then the total impedance will be 2 ohms. Similarly, if you wire 4 speakers together, the total impedance will be 1 ohm. Wiring a 2 ohm speaker to an amplifier rated to drive a 1 ohm load should work without any problems but expect the total power output to be somewhat lower than with a 1 ohm load.
If wired in parallel then 4 ohms.
Four 8 ohm speakers wired in parallel would give an effective 2 ohm load.
nope
2 in series with 3&4 in parallel
Use a multimeter or digital multimeter and set it to the ohmmeter mode. Put the test leads on the speaker terminals. It won't be perfect, but if it says 1.8 ohms or so then it's a 2 ohm speaker.
