New guy here with a few questions. I just got a 2001 Protege ES 2.0 and the only two problems it had was a window regulator which I fixed myself, and the headunit. The headunit is starting to cause me some problems and I have no experience with stuff like that so I'd like to know if this problem is fixable. My back speakers only work if I'm pushing hard on the radio and when i'm not sometimes they cut in and out and sound really choppy. The display on the radio is also only half showing up. Does anyone have any ideas? Sorry if I'm lacking detail, I'm new to this!

 

radio/ headunit issue check for any loose connection

 

Behind the headunit?
