What size wire should i have for two 12 volfenhag subs


I would use 10 to 12 gauge wiring. As fare as your amp's fuse...Check to make sure you are using the correct amp fuse. Make sure your subs are wired to a ohm load your amp is stable with. Check your ground and positive connections. Check and make sure your amp's gain settings are correctly set. Your amp's gain should not be turned all the way up.

I need to know how many ohms this speaker should measure on my digital volt/ohm meter, i'm getting 2.1 and 2.4 ohms.


hi
You speaker is dual coil one. Each coil have an impedance of 4 ohms. When these coils are connected in parallel then the ohms will be 2 ohms and in serial it will be 8 ohms. slight variations will show in digital multimeter when you measure the ohms. use the lovest ohms range in you meter to measure the coil impedance.
ok

How do you repair the voice coils in the subwoofers?


if it is just one of the coil wires that have disconnected then you can try resoldering them but if its the actual coil then your out of luck. you should take it to a speaker repair specialist so they can rewind it. or just trash it and but another sub.

How to wire the dual voicecoil


if you have a 2 channel amp, just wire each coil to each channel....If its a mono amp or you are bridging amp, hook up one channel like usual (+ and -) then use a jumper wire from the positive to the other positive on the speaker and do the same for the negative....

Manual for 12" 1000w Valfenhag Subwoofer


Unfortunately there are no manuals for subwoofers as far as I know. For optimal performance there is really only one size for the box .Firstly, you get two different types of subwoofers, an open air, or closed air sub. If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long. Box size will be 13 inches x 13 inches x 13 inches

Volfenhag ZX4725 i am buying this subwoofer and


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) see below. http://en.wikipedia.org/wiki/Audio_power

http://www.hometheaterhifi.com/volume_1_1/v1n1spk.html

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. http://www.diyaudioandvideo.com/FAQ/Wiring/
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.

Best way to connect a 15'' kicker cvr15 4 ohm dvc [single sealed box] and a volfenhag zx-4712 1000w 12'' 4ohm+4ohm dvc to my pyle 885 1000w 4 ch. bridgeable amp and how to wire the voice coils that are in...


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.

Finding the best amplifier


Hello sharky75,

That 1600 watt peak power figure for your subwoofer can't tell you what amp you need. You need to know the maximum RMS power the sub can handle. And you need to know the impedance (ohms) of the voice coil(s). JBL GT5 series subs have an RMS rating of 275 watts. The GTO series handles 300 watts. The Power series handles 400 watts. The GTi series handles 700 watts. Some are single voice coil, so the impedance is fixed. Others are dual voice coil allowing you to wire them for different impedance loads.

For maximum performance your amp should be able to provide at or near the same number of watts RMS into the lowest impedance at which the sub can be configured. For example, if your sub is the Power Series Model number P1224, it has dual 4ohm voice coils and can be wired to present either a 2ohm load (parallel) or an 8ohm load (series). You want to wire the voice coils in parallel for the 2ohm load and select an amp that outputs up to 400 watts RMS into 2ohms. The Orion Cobalt CO8001 is just such an amp. If you have one of the GTi Series subs, a better amp would be the JVC Arsenal KS-AR75 which outputs 700 watts into 2ohms.

Hope this helps.

Zx-8400 amp too much for zx-4812?


The amp and sub combo should work fine the subs can really take a crapload of power-i have a neighbor thats running 1200 watts rms to each sub in his caddy and OMG- its sick. Your amp should be pushing around 800 watts rms(continous) to the sub which should do very well-my concern with your setup is that the sub is designed for a vented box- you can use any box u want but im just suggesting that you use a good solid vented box with these subs- my other concern with your setup is that having only the single sub if its a dual coil 4ohm + 4ohm coils then you might run into trouble if you dont have it set up right-by that meaning to get all the power handling capability of the sub you would want to use both of the coils right? well to do that you have to either wire the coils in series or wire the coils in parallel right? In series the coils will yield an 8 ohm load to the amp and youll only get about 400 watts from the amp bridged into that 8 ohm load- on the other side of that if you wire the coils in parallel then the cols yield a 2 ohm load and that could cause the amplifier to become unstable and fry its little guts. All of this is assuming that the amp is made to run bridged at 4 ohms- if it is 2 ohm stable in bridged mode than you have nothing to worry about. Now the popping noise- that sounds like its coming from the amp somehow and just feeding through to the sub-like you ive never heard a sub popping unless its bottoming out and you say its not so its gotta be the amp id say-if it were me id check all power connections especially the ground for the amp . It could be that on the heavy bass notes that your amp is not getting enough juice -throw a 3.5 farad capacitor on the power line and see if that helps your system out-

Subs stopped working & protect light on the amp is red...


well at this point i would say it is both,, the subs fried because your amplifier passed dc [direct current] and fried the voice coils on your subs....return them if they are under warranty,, the amplifier sound like you either operated it beyound its specifications or it has a defective output stage allowing it to pass or leak dc....it turned the voice coils into the equivelent of the runners in a toaster oven....when an amp passes dc it is going to do so to whatever speakers you hook to it....so either bring it to a shop to be fixed/ return it to place purchase for exchange or throw it away.....or you will continue to experience the same problems....I am sorry..ps the amp goes into protection when it detects a short...[ the short is produced by the amp and it is detecting its own fault and putting it in to protection after it BURNS up your drivers....
