Hi everyone. I'm pretty new to diy home stereos and I'm having issues with my project. I ordered a small amp and had nasty feedback. I tried a GLI and no luck. Thought the amp was defective so I replaced it. The new one is installed and sounds a lil better but still humming. My project receives audio from a tablet I had. I unplugged the 3.5 and still hums. Very lost.

Try posting a picture of your amp,

You need to give more information about power supply used and how you have connected it up.
Then you might get someone to give you ideas to try.
