If you look at the right hand terminal

On your first picture . You can see that the solder isn't a nice shiny blob. (actually its the one just to the
left of the two wires with the tape around them the on on the extreme right is a little better.
This indicates a cold solder joint which can mean an intermittent or high resistance connection also its long term viability will be in question .

Do a google search on cold solder joints.
Do you have a multimeter with which you can check continuity and resistance.
You might want to run some checks on your connections speaker resistance
to the amp , power and ground connections.
