Question about Volfenhag ZX-8200 Car Audio Amplifier
The amp keeps shuting of at low volume and when its not doing that protect mode will come on at low volumes sony xm-d9001gtr
It is not always the amp ic's, in fact this amplifier has discrete outputs, not ic's. This amp is a D class mono sub woofer amp.If the amp turns on but shuts off at low volume it is likely that you have an improper load. It is rated for 2 ohms to 8 ohms. I would advise using a 4 ohm load since it is not as stressful as a 2 ohm load. Your speakers may be at too low of an impeadance or shorted or shorted speaker wire.I have seen many times when people connect too many speakers to the outputs it causes the impeadance to be too low and the amplifier will shut down or overheat or go into protect mode. Try connecting just one 4 ohm speaker and see if it still goes into protect or shuts off. If it does, then you do have a problem within the amp. It could be leaky output transistors or even something in the power supply of the amp. If it plays properly, you have a bad speaker or improper speaker set up. More information is needed to give a better answer. How many speakers, speaker impeadance, speaker configuration. This amp has speaker jacks for 2 speakers, but they are in parallel together. If you connect a 4 ohm speaker to each speaker jack, you have just created a 2 ohm load. If you have two 4 ohm speakers on each jack, you have a 1 ohm load which is too low of impeadance for this amp. The positive terminal for each speaker jack is the same point electrically as is the negative jacks the same point to each other. It is like the positive jacks are tied together and the negative jacks are tied together.
