Experiencing a new issue with my setup. I have a stock HU with a SS PN4.520 amp and 4 MM651 speakers. I am getting sound out of the headset if I have one connected but if I flip the switch where i would normally get sound out of my speakers, I get nothing. Opened the fairing this morning to check all connections and fuses; they all look good.

Thoughts/Suggestions??

 

is the amp powered up with the green light?
is the red protection light on?

 

yes to green power light and no to red protection light.

 

got a spare speaker (even a stocker) that you can connect to the output of the amp to see if you're getting any sound?

and if so, and you do have sound, then move the speaker to the end of the speaker wire behind the crossover (where the speaker is actually plugged in) to make sure it's ok as well.

if no sound then we'll have to go a different route in troubleshooting...

 

Connected a stocker to the front and rear right channels and no sound. Other thing I noticed was there is no noticible click then i change the switch from headset to speaker. Still getting sound from headset and icons on the stereo change but no noise.

 

did you connect at the amp in front of the crossovers or behind the crossovers at the actual speaker plugs?

just trying to make sure all bases are covered before we call it a bad amp. Would hate for ya to pull it and it be something else.

 

Connected right at the amp output screws. Nada

 

ok now I need you to test the speakers coming off the head unit itself. take the amp out of the picture altogether.

 

Can I just jump the speaker from the wires to the amp or should I unsolder them completely?

 

if you're referring to the white plugs.. sure you can tie the speakers directly into that.
