Hi,
I'm testing an amplifier by connecting it to an ATX power supply. My audio source is an iPhone and the load is a 50W car speaker (small, usually mounted in door). The problem is, that the output volume is very low (unconnected iPhone plays louder). Besides that the sound is distorted, especially low frequencies. I tried changing source to laptop, but the result is the same. I would appreciate any thoughts on troubleshooting this device. I also may add more info if needed.
