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.

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

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.

I recently bought two of these subs and the box they were in has cracked at the bottom whats the proper size box and should I get a bigger vented port box because they seem not to be producing the amount...


Ensure the audio system is capable of delivering output power required by the subwoofer, obviously bigger vented box will result in greater air flow and produce better bass, but it should not be to big. you can try for boxes with more depth.
To enhance the bass you can try connecting a capacitor of 470 - 2200 micro farad across (parallel) the speakers. try out with smaller capacity capacitors first

I have a volfenhag zx-8400 amp. i dont have a manual. whats the proper way of conecting amp? its mounted on my speaker box, which is ported, 12' volfenhag 2500 watts. on the side of amp it had voltage...


The voltage prolly says like 100Mv-2v, it doesn't really matter, just know that that the lower you turn it the harder it bangs. The X-over depends on where your box is tuned, crank the knob down too about 40htz and you'll prolly be good, just don't turn it lower than your box's tuned frequency. And your rca's go to line input. And there shouldn't be a problem with mounting your amp vertically, you prolly just had a bad connection. Hope this helps if you have more questions please ask...

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.

Is it enough to power to 12 volge=ahagen 12oowatss dual 4 ohms


your Volfenhag 12" subs are rated at 1200 watts they are only 600 watts rms and the Rockford punch p4004 is only 200 watts rms so the answer is yes it will work but if you get a amplifier that pushes out 500 - 600 watts rms you will love the sound from subs
there is nothing wrong with the Rockford amp it just wont pound out the bass as hard but the good news is you will never blow the subs with it
when buying amps or subs make sure to look at rms rating that is the true power they actually have ie. (sub box says 1200 watt you think powerful but if you divide it in 1/2 you actually get 600 watts rms) don't get me wrong that's a nice rating. for a sub but you will want to match that number with the amps rms rating or lower. The RMS is what makes the car pound the higher the RMS the better
hope this helps

Power sub plate amp replacement


Why not try to find a used working similar model sub instead of replacing the amp? any amp different than the one built in will provide a sligtly different sound.
