    How would you guys consider wiring them?

    If you take one subs voice coils and wired into parallel then connect each speaker to a single channel you would get the best and easiest results.

    the specs (from the link you provided) state;
    ~
    300 watts RMS X 2 @ 4 Ohm Stereo (600 watts total)
    380 watts RMS X 2 @ 2 Ohm Stereo (760 watts total)
    760 watts RMS X 1 @ 4 Ohm Bridged (760 watts total)
    ~
    method #1
    connect one voice coil from each speaker to a single channel, leave the other voice coil on each speaker disconnected.

    -this will present the amplifier with a 4-ohm load in stereo mode. since amp usually output less distortion at higher impedances, this will probably have the cleanest sound output, but will not be as loud as the other methods.
    -DO NOT WIRE IT LIKE THIS! WHEN ONLY 1 VOICE COIL IS HOOKED UP, IT CAN ONLY HANDLE HALF THE POWER. THAT AMP IS TOO POWERFUL FOR ONLY ONE VOICE COIL TO BE HOOKED UP!!

    method #2
    wire each speaker's voice coils in parallel to achieve a 2-ohm [per speaker] load, then connect each speaker to a single channel.

    -this will present the amplifier with a 2-ohm load in stereo mode. the sound may be a little muddier, but will also be louder.

    method #3
    per speaker, wire the voice coils in parallel to achieve 2-ohms. then wire the speakers in series to achieve a 4-ohm [total] load. you should only have 1 positive and 1 negative speaker wire; connect these wires according to the amp's bridged [single-channel] output terminals.

    -this will present the amplifier with a 4-ohm load in bridged mode. this makes both speakers act as a one big speaker.

    method #4
    per speaker, wire the voice coils in series to achieve 8-ohms. then wire the speakers in parallel to achieve a 4-ohm [total] load. you should only have 1 positive and 1 negative speaker wire; connect these wires according to the amp's bridged [single-channel] output terminals.

    -although wired the opposite way, the end result is exactly the same as method #3.

    method #5
    per speaker, wire the voice coils in parallel to achieve 2-ohms. then wire each speaker in parallel to achieve a 1-ohm [total] load.

    -this will present the amp with a single 1-ohm load.
    -DO NOT WIRE IT LIKE THIS, THAT AMPLIFIER CANNOT HANDLE A 1-OHM LOAD. IT MAY DESTROY THE AMP AND/OR BLOW THE SPEAKERS AS WELL!!

    as you can see, you have a few options with multiple DVC subs. I personally would go with method #2... good luck

    I'm sorry, but I wish to disagree on this method. I'm sure many people will back me up on this one, but when you have a dual voice coil sub, you must always wire up all of the voice coils. It will create an unsafe condition with the sub, and most likely blow it. There aren't any respectible manufactures of those products do not design them in that way nor do they recommend any such use of their products in that maner.

    i disagree with you. one of the reasons why they came up with dual voice coils is so you can have multiple wiring options. you can run one coil all day long but it will only handle half the load. look it up :-)

    no, you don't ALWAYS have to wire the coils together. as long as you don't exceed the power handling capacity of each voice coil, then there is no danger of blowing the sub.

    however, in this case you are correct; those subs should not be wired using method #1 (I will edit the post to reflect this). the reason they should not be wired like that is because the misleading power specs for that speaker apply to BOTH coils wired together (each coil can only handle 1/2 of that rating).

    the same is true for another traditional DVC sub hookup method which involves connecting one voice coil per amplifier channel. many people use this method to hook up a single DVC sub to a 2-channel amplifier. the main reason for this is because many amplifiers will output more power in 2-ohm stereo mode than they will in a 4-ohm bridged mode. in that example, people who only want 1 subwoofer (for space reasons) can get more power out of their 2 channel amp by hooking up a single DVC subwoofer in stereo mode (as opposed to a single SVC subwoofer in bridged mode).

    on this point I completely disagree... the design of the sub is irrelevant. the difference is the way they choose to rate their subs power handling specs. IMO a respectable manufacturer will rate a DVC sub the same way an amplifier is rated (per channel). a DVC sub is similar to a 2-ch amplifier (a 2-ch amplifier is a single device with 2 independent outputs, a DVC sub is a single device with 2 independent inputs).

    unfortunately, like many audio/computer/electronic component manufacturers, they choose to only list the numbers that make their product more appealing to it's [ignorant] buyers. if they listed it's true power specs [per coil] then the subwoofer would appear to be "weaker" even though it's the same physical subwoofer.

    NOTE: I'm not saying that kicker is a bad brand, in fact I think they make very nice subwoofers; but I look down at the common practice of listing misleading specs for marketing reasons.

    The properties of these electronic components are those of an inductor, since it is a coil. And when power is applied to the coil it creates its own magnetic field. And through the magnetic field, inductors resist change in current. But in this construcion, when 2 separate coils within such a close proximity to each other it begins to resemble a transformer. While one coil has power applied to it, the magnetic field created is absorbed by the other coil and charges the unused coil to create a voltage. This may be considered mutual inductance, the concept that the change in current in one inductor can induce a voltage in another nearby inductor. This can also result in coupling, where, in this case, unwanted energy can be transfered from one coil to the other, and vice versa. Simply put, the first coil can potentially charge the second coil causing increase or opposition of the original power supplied to the first coil.

    Being able to wire it up it that way may be true with some subs (I have yet to read such documentation), But with this case, the documentation for this sub states, "Solo-Baric subwoofers are available with dual 2Ω (ohm) or dual 4Ω voice coils. Both coils must be connected to a source of amplification." ...yada-yada-yada... With most documentation the 2 main types of wiring configuration for DVC speakers are series and parallel. In fact the weakest type of wiring would be to wire it in series, a DVC of 4 ohms each would create 8 ohms.
    I completely agree that you can wire up a single sub to multiple amps is possible, given done safely and correctly, but I wouldnt recommend wiring each coil seprately to a stereo 2 channel amp. Given there can and will be the situation where the output of sound has differerent frequencies being played on the left or right side may cause each coil to move in opposing directions. I only recommend such a connection when the amplifier has a mono setting it can be changed to or a mono signal is sent to both channels of the amp.

    In this case, Given you are using that amp with that sub, attaching only a single voice coil will not give the full potential of the combination.

    I like healthy and thought provoking debates? :P
