The Alpine 10" Dual-Voice-Coil 4-Ohm Subwoofer is considered the industry standard for range in subwoofers.
Subwoofers draw a lot of current when played at louder volumes. Thus it is either preferable to use an amplifier which can produce as much RMS (not peak) power as the subwoofer's power rating, or to be sure not to overdrive the amplifier since this produces audio distortion. Audio distortion can burn out the voice coil within a speaker.
It depends on the amplifier. If you absolutely want to leave the current subwoofer configuration as 2ohm and 4ohm, the resultant impedance seen by the amplifier is as follows: Both wired In-Series: 2ohm + 4ohm = 6 ohms Both wired In-Parallel: 1 / ( (1/2) + (1/4) ) = 1.3 ohms The Parallel configuration can probably be only run by a 1ohm-stable amplifier whereas the 6ohm Series configuration can be run by any amplifier that is able to drive anything under 6 ohms. Also if ran in the Parallel configuration, this mismatch in driver impedance may also cause the 2ohm subwoofer to receive more power, resulting in a different sound characteristics than the 4ohm subwoofer. Usually with DVC subwoofers you want to match the impedance between drivers. If possible, configure each subwoofer to 4ohms and connect them in Parallel. This will produce a total impedance of 2 ohms (you need a 2ohm-stable amplifier). If your DVC subwoofers only support 2ohms and 8ohms do either: Both wired In-Series - configure subwoofers to 2ohms: 2ohms + 2ohms = 4ohms Both wired In-Parallel - configure subwoofers to 8ohms: 1 / ( (1/8) + (1+8) ) = 4ohms.
When connecting a dual voice coil sub in series you should use the powered subs.
a voice coil is the electromagnet that causes a speaker horn to move in response to the electrical impulses received from the amplifier.
you sing through a microphone and it makes the voice louder. the sound of the louder voice comes from the amplifier.
First if you are talking about normal speaker (not subwoofer), I would not recomend doing that. There is different ways to connect multiple speaker to one amplifier chanel. You could wire it in serie or in parralel. If your are talking about dual voice coil or more than 2 speaker, there is even more possibility to wire two or more speaker to one channel. Now if you are talking about single voice coil subs, in a perfect situation, by wiring them in parralel, the wattage should not get lower but the impedence will be divided by the number of sub you hook up. You will need to make sure the amp can support a lower impedance.
A microphone, by itself, does not make your voice loud. It changes the sound waves your voice makes in analogous electric signals. These signals can be sent to an amplifier and speakers to make you voice sound loud. The amplifier increases the amplitude of the electric waves so that when they are sent to a speaker and changed back into sound waves, they will be louder.

a car subwoofer is better because it dilivers clear and louder sound then the computer sound speakers but the sound speaker are better for the voice it depends what you are using them for.
Its probably not a terrific idea, but as far as I can tell, nothing has ever happened to the amps that I have done this with. It simply limits the reproduction of your voice through the speaker, as it was designed for guitar frequencies. However, like I said, you should be golden.
