Question about Dual 2-Channel Bridgeable MOSFET Amplifier (XPA4100) Car Audio Amplifier
I purchased a Dual head unit a year or so ago from BestBuy.
Around 3 months ago, my volume suddenly began acting up and when i turn the volume knob counterclockwise to lower the volume, it became louder and is not stuck on the max volume.
So now, i can't turn it on to listen to music or the radio since im afraid i will blow my speakers. Does anyone have an idea of what may have caused this problem? Any help is greatly appreciated. Thank You. (by the way, BestBuy wont do anything since i lost my receipt from a year ago, and apparently, they don't have any record whatsoever of my purchase on any of their computers??? B.S.)
It sounds like the POT has gone bad, I assume it is a digital volume control right. if you turn it down slowly does the volume go down. if so its the POT

You can try contacting the manufacturer to see if it can be repaired.
When you have this type of problem, it's generally due to the rotary encoder failing. It's unlikely anyone else will have parts.
