Hello. Using Adafruit MP3 shield. This is the non amp version.
I have a soldered connection from the Line Out +/- to an amp, however I am not getting any signal out. Works fine when using the headphone jack. The description says these can be used as line out, however I don't think it works without the amp build in. Am I incorrect? Is there a workaround. The solder joints are fine so its definitely not that.
Thank you

Still if you could post pictures of your connections and the specs on the amp you are inputting to it would help.

Solder has good contact all around. Picture was taken with phone, sorry for quality...
It works very well with the headphone connected to the amp.
Here is the amp: http://www.parts-express.com/6x100w-tda ... d--320-307
Is it possible that the there is no signal on the line out if the built in amp is not included?
Thanks for the help.

Also, if this will work without the built in amp, will these terminal blocks you sell fit the MP3 shield?

It looks like the terminal blocks are output from the amp only and you would have to create a cable that plugs into the headphone jack to get to the signal.
