Volfenhag Popular Questions, Answers, Tips & Manuals

This is all I could find; https://www.upcitemdb.com/upc/712952938217

It looks like there is no manual. Although it has a German name, it looks like it is made in China and sold by Sonic Electronix and Amazon. Sonic's website says it is down for maintenance, but my guess is they have done a runner! This is the only place with any help. https://www.the12volt.com/installbay/forum_posts.asp?tid=86807 If there was a manual, this would find it. https://www.google.com/search?q=volfenhag+digital-xm+Zx-8400+manual ..

Request the diagram from Volfenhag.

Sure. If you want to spend about $100 on a recon kit. Honestly volfenhag is a flea market brand and not worth fixing.

How to wire amp?

What subs/spks do u have? How many?

I would use a 4 gauge wire for the power supply to the amp and a 4 gauge neg of the amp

No, it's only use to control the gain or level from zero to what u set it to

try looking for mfg name, place where they were made, state or country, zip code, part numbers, any information here is a website that may help: www.alltheinternet.com/ www.thesearchenginelist.com/ www.infolinks.com/ www.searchfiles.org www.wikipedia.org/ www.wiki.org/ www.hackipedia.org/ /rebuild power inverters 2500 watts /volfenhag 12 manufacture+service+rebuild /repair+fix ZX-4812DVX

there maybe have a broken connector inside the unit, when you move the cord around you get a little sound, if you know that the sub are good, than its either the connector or wire issue, is ther reset on the amp any where. you could try another speaker if you get the same results its the amp or connector device in the amp. if it not in warranty you you want to check it out than take it aprt look and see if you can fix it your self or trash it.

ZX 8290 Volfenhag 2 Channel 1200 Watt Bridgeable Power Amplifier

if the protection light came on even though you was not powered up means there maybe a internal issue with the unit, i would be careful with that unit.

stop using the unit, it may blow up or start a fire.

a transistor has 3 leads,[emitter current, collector current, base current, i am going to give you list of options that the transistors can be used for and it depends on the configuration of the circuits. input resistance, current gain, voltage gain, output resistance, power gain, voltage gain, (input and output power) + [input and output voltage] and {input and output resistance} + input and output power gain. 18 various formulas to a range in groups of 2's

Without knowing how it's actually laid out, I'd surmise the output amplifier transistors in the right channel are shorted, the fuse for that channel may be blown, and the speaker protection circuit is keeping it turned off. Most amplifier speaker protectors disable both channels if there is a problem, but yours could be different. I surmise the lights you mention are directly connected to the speaker protector chips and indicate readiness for normal operation. If it takes a few seconds for them to come on after power-up, that lends credence to my hypothesis. Unplug the amplifier, open it up, and measure the resistance from the right channel output to each of the output power supplies (or to the fuse for the output power supply for that channel, if present). If one or both is very low (i. e, close to zero), you have a fried transistor. If that is the case, it is probably a good idea to replace the complementary transistor connecting the speaker to the other power supply even if it tests good; it may have been overloaded when the first one shorted. In many amplifiers, the transistors are inside a hybrid amplifier module, so you would have to replace the entire module. In some amps, you have multiple transistors in parallel; here you can probably keep the transistors that were in parallel with the failed unit, but I'd still recommend changing the complementary transistors.

the power amp has a short in the unit and it drain everything out of the battery, that why the battery is dead. it is really possible that a capacitor is open or shorting out cause the unit to drain the battery.

try contacting the manufacture of the device. its going to take some research to find the company, if you go to the local library they should have some book or information on manufacture places, locations, phone numbers, where to contact them, it has been a while since i did that type of work when i did it they had 15-20 4 inch thick under manufactures, look under name, paten ## another way to find the vender, find out whos sales it and contact them for dealer info, or contacts. www.thesearchenginelist.com/ www.wikipedia.org/ www.wiki.org/ www.askives.com/ www.infolinks.com/ www.searchfiles.org/ www.alltheinternet.com/ /directories services for zx-7180 car audio amplifiers /car audio amplifiers for volfenhag [ Europe ] / try various wording

make sure you mount where you can get a good ground and where it can get enough air to keep cool. underneath the car seat is where a lot of installer put the amp, and if you are going power up a lot i would think about mounting a fan to blow air on it to keep it cool. i have fans connected to my laptop power supply transformer to keep the unit cool, here other ideas you will never be told, putting little holes around power supple, fan area, any where there a lot of heat is generated the air flow helps it stay cooler while powering up the amp. good luck and be safe rod

try again and again
