Protect mode hello i sort of need help about my volfenhag zx-7100 amplifier i had it playing in my truck one day and all of a sudden the music started to get a static like sound and all of a sudden the amplifier went into protect mode(red light) on the amplifier

ZX 8290 Volfenhag 2 Channel 1200 Watt Bridgeable Power Amplifier

volfenhag's are cheap. you get what you pay for. that is the german equiv. to pyramid or kraco.

The protection light is on indicating a short or over- voltage problem. If you disconnect the speaker leads and the light goes off or green then the problem is a shorted speaker or wiring problem. If the light stays red the problem is inside the amp and it will need service and parts.

That probably means that it's getting a surge of power. Do you have a fuse from your battery wire to your amp? Check also your ground wire. You may need to upgrade your ground wire.

The most likely problem would be a blown fuse. I would replace all of the fuses.

Hello youngbossrio,

Like other car audio capacitors, the Volfenhag zx-hypercap has two terminals, a positive and a negative. The negative terminal is connected to the metallic frame of the vehicle (ground). The positive terminal is connected "in-line" with the amp 12V positive terminal.

The capacitor should be as close as possible to the amp. Within a couple of feet is acceptable.

The capacitor needs to be "charged" before connecting it directly to 12V positive. This is done with a 1000 ohm resistor and a voltmeter. The exact value of the resistor is not critical but it should be in the 500-1000 ohm range. Use at least a 1 watt resistor (your capacitor may have come with a resistor for charging).

Hope this helps.

If you unplugged the fuses, the amp won't come on at all. I'd say its a blown transistor, you can test this by opening up the amp and using a multimeter to check resistance on the transistors.

its very easy to hook it up. your best bet is to join www.carstereo and ask your question there.but it is easy to set and hook up amp if you really need help email me

It's likely that there are shorted output transistors in at least one channel. If you want to repair it yourself, you'd have to determine which transistors are defective and replace them. The following page will help guide you through the basic troubleshooting.

Is ur unit brand new? if thats brand new ofcourse 90 percent OK. You identify first the rear and front speakers (left & right). Beware to short circuit the unit. short circuit may cause damage ur power out..Set up first the speakers before you conect the power supply..hope i help you even a little...thanks..
