SOURCE: how to wire a volfenhag dual coil sub

U HAVE TWO COILS ONE ONE EACH SIDE OF THE WOOFER, ALL U DO IS HOOK UP ONE COIL TO THE OTHER, THEM HOOK THEM UP TO THE TERMINALS IN THE BOX.

SOURCE: is my amp powerful enuff for woofer

That amp should work fine for that sub, but you should make sure that the amp has a good power system going to it, and the box for your sub is the right one. Either one of those things could cause problems if not done correctly.

SOURCE: best way to connect a 15

best way is to just run the volfenhag with a set of wires for 2 channells(one set per coil) left and right @ 4 ohms per channell. The CVRs you can parallel the coils(2 ohms) and run a set from each sub to the amp in stereo left and right. This will give the kickers a little more juice than the 12 but should be fine.

No the LOWER the resistance the MORE Output or Draw, If say it is 100 Watts into 4 Ohms, if you used a 2 ohm speaker it would draw 200 watts.(only if capable of delivering that amount of power) The LOWER the Resistance, the HIGHER the Current Draw.
WATTS = AMPS x VOLTS. (This is not strictly true with amplifiers output though, as it is an AC Current, and a "Reactive" load, it has, Inductance, Capacitance and Resistance, all in one.and is worked out via a Formula)

Now with Dual Voice Coils, Essentially, you can think of these speakers as TWO speakers in ONE enclosure. As such, They are basically TWO Speakers. Please see the website below it explains everything for you.

Everything is a function of Resistance and Ohms law.

Current (I) = Voltage (E) divided by Resistance(R).

Voltage = Current Multiplied by Resistance.

Resistance = Voltage divides by Current.

SOURCE: I need to know how to wire duel voice coil 12

one way if you want to run it off 1 channel is to wire one voice coil to the other making sure +goes to +, and -goes to -,then wire your amp to one of the coils, but i found just running each coil to a seperate channel on the same amp was the best way,

Two things I need to know

1 Make and model of Amplifier you intend to use

2 Is it going to be a single sub or 1of a pair

Wire in series for 4R. +ve of coil to amp +ve. -ve of that coil to +ve of second coil and the -ve of the second coil goes to -ve of amp.

try wiring them differently. here is a link for u to go to http://www.crutchfield.com/learn/learningcenter/car/subwoofers_wiring.html . once there find your amp configuration (ie. mono, or 2 channel) then down to the type of subs an how many subs ( ie. 2 dvc (dual voice coil) 4 ohm subs) an that will show u how the subs should be wired and wired to the amp.

Well without seeing a spec sheet on the amp and not knowing your voice coil impedance I will assume the following. If the speaker is dual 4 ohm voice coil the in parallel it would present a 2 ohm impedance to the amp. If this amp is stable down to 2 ohms bridged then that would be the hookup of choice. If it is not stable to two ohms with one speaker it will be tough to get full performance out of your amp. You would have to series the voice coils which would then present an 8 ohm impedance to the amp. Just look at your amp's manual before making the decision. My suggestion would be to get another one of those subwoofers parallel the voice coils on each then wire the two subwoofers in series. This would give you a 4 ohm load which your amp is almost certain to be able to drive.

The easiest way to think of wiring voice coils and subs is this:

- Two items of the same impedance in parallel = Half of the impedance
- 4 ohms in parallel with 4 ohms = 2 ohms
- 8 ohms in parallel with 8 ohms = 4 ohms
- Two items of the same impedance in series = Double the impedance
- 4 ohms in series with 4 ohms = 8 ohms
- 8 ohms in series with 8 ohms = 16 ohms

- DVCs in parallel, 2 subs in series = 4 ohms
- DVCs in series, 2 subs in parallel = 4 ohms
- DVCs in parallel, 1 sub = 2 ohms

Mar 16, 2008 | Car Audio & Video

The amp is rated to run a 2 ohm load on each channel. To do this, connect the voice coils of one sub in parallel (tie both "+" on the sub to each other and both "-" on the sub to each other), then connect that sub to one channel of the amp. Repeat this process for the other sub and connect it to the other channel on the amp. The subs will be in stereo and the amp will be outputting it's maximum power.
