If you want max power flow connect the coils in parallel. Positive from 1 post to positive on the other post and same for negative. Then chose one post and run the positive to the positive of one channel on the amplifier and the negative to the negative of the other channel. That is called bridging.
you don't light the car on fire and make it explode
Depends if it is dual 4Ohm or dual 2Ohm and what Impedance your Amp supports. *If you amp can handle 1Ohm Load and you have a dual 2Ohm sub you can run the sub in parallel to get a 1Ohm load (parallel meaning both + are connected with each and same with both -) *If your amp can handle 2Ohm load and you have a dual 4Ohm sub you can run the sub in parallel to get a 2Ohm load. *If your amp supports a 4Ohm load and you have a dual 2Ohm sub you can run the sub in series to get a 4Ohm load. (series meaning the - from one coil is to be connected with the + on the other coil) Do not mix up Impedance's make sure you find out what your Subs Impedance is and what you Amps Impedance is
When connecting a dual voice coil sub in series you should use the powered subs.
mono or two channel are the best for subs but it depends on if your sub is dual voice coil or single voice coil, what ohm load the amp can handle, and if it is single voice coil and are using one sub you need to make sure you can bridge a 2-channel amp if that's the kind you chose... Next question you ask it may help to add a bit more detail. If I knew the sub brand and model, ohms, and if it's dual or single voice coil i could help answer that much better.
The Legacy Car Audio LW1549 comes with a 2.5'' High Temperature Dual Kapton Voice Coil.
You could with a 4 channel amp. Bridge it to two channels and hook up the two 8 ohm woofers in parallel on the one bridged channel. Then hook the two coils on the dual coil woofer in series with the other bridged channel on the amp.
If you are going to replace a dual with a single you need to look up bridging it would be some thing like "{Right +}{Left -}
with only one coil hooked up, a dual voice coil speaker will suffer a loss in reference efficiency of about 3dB (only half the coil windings are being energized) as well as a significant shift in its Thiele/Small parameters. This renders any enclosure calculations inaccurate unless you remeasure the speakers parameters with only one coil hooked up. Failure to account for the different parameters of a dual voice coil speaker with only one coil powered can result in very poor performance.
to mono if your amp will allow, also this is for single voice coil. otherwise run in mono parallel to run dual voice coils.
AnswerDual Voice Coil in regards to subwoofers means there is 2 positives and 2 negatives. Its just used to wire up different ohm levels. Like if u have a subwoofer that are dual voice coil @ 4 ohms then u can parallel or series wire it to become Single Voice Coil @ 2 ohms. Google the word Series Wiring or Parallel Wiring for examplesAlso this type of speaker is one of the few that can be connected to 2 different amplifiers at the same time and still work properly. One coil is connected to the car stereo and the other coil is connecter to my scanner.
The Alpine 10" Dual-Voice-Coil 4-Ohm Subwoofer is considered the industry standard for range in subwoofers.
6.5" 2 ohm in the doors, plus 1 inch 4ohm tweeter if you have monsoon 6.5" dual 4 ohm voice coil subwoofer in the sail panel. (highly recommend Elemental Designs) 4x6" round 4 ohm speaker + 1" tweeter if you have monsoon. There are no 2ohm voice speakers that I know of, so your sound output will be slightly lower with aftermarket speakers. If you dont have Monsoon, then you have 6.5" 4 ohm speakers, standard replacements apply.
