Okay here is what I'm trying to do:
I build the audio amplifier based on TDA2003 (Pic attached) which is working fine with my xm-radio.
But here is another thing I'm trying to do. I have a gps unit where I removed speaker and put a headphone jack instead. Now I am trying to connect it to this amplifier and it doesn't work. The thing is that amplifier uses ground as one side for input and gps doesn't have a grounded output. It is about 86KOhm between each output wire and actual ground.
So is there is anyway I can connect a device like that to an amplifier?
Thank You.
