Making Bad noise

Hey guys,

To start off it’s great to be on this forum and it’s going to be good talking to all you guys, also I had no idea where to post this so if it is in the wrong area let me know and I will move it.

from last few days my sound system making a bad noise. my friend said I need to change the cable. but I can't find near me. so I searched on the internet and there a lot

so I am here to get a help to chose the best one.
