Question about Volfenhag ZX-4712 Car Subwoofer
Ok first questions were is the serial number located on these subs? Ok well I bought 2 VOLFENHAG 2000 W SUBS and VOLFENHAG ZX 7180 2 CHANNEL 1600 WATT AMPLIFIER Item URL:http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130094810110&sspagename=ADME:B:AAQ:US:1 My brother in law and I installed them just fine. Then a few days later one of the subs stopped working and the protect light on the amp started turing red. We took a closer look and noticed that the sub just kept making a hissing noise, and you could smell something burning in the sub, my brother in law said it may be the voice coil. So we took that one out and just had the one left hooked up. Except the next day that sub stopped working and the protect light on the amp is turning red again. I havent had time to check this one out yet, im been busy with college. We plan on trouble shooting and see what we can find out. My brother in law has the same subs as me but with a different amp. What i need to find out is if its the amp or the subs. Any help or suggestions are GREATLY appreciated. I would like to figure out the problem so i can send what i need to back and get new ones as soon as possible Thanks Corey Johnson
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....
