Factory Radio Trouble Shooting

[90BlackMJ]

Hey guys, I’m in the process of putting my Comanche back together from restoration and upon testing the radio, I get nothing. 
 

The radio is a unit I bought from Jeremy (Minuit) so I think it should be good. All 4 speakers are brand new from crutchfield. 
 

I get power and can scan through channels, but no sound. 
 

Any help is appreciated! Would like to troubleshoot this before I get too far back together with the interior. 
 

thanks.

Pull the nob off the volume button and crank it to max.

 

Do you hear any hiss at all or complete blank?

Do you have the corrct +/- pairings, so two greens or two purples for example example?

I will try the knob thing and see what happens. 
 

also the polarity should be correct as I used adapter harnesses at each speaker. 
 

I will double check and send info on what I come up with. 
 

thanks!

I took a video of what’s happening, which is basically nothing. Too big. 
 

I can turn radio on. Scroll through all the presets, turn volume up and down, but I get zero sound or zero static.
