Where is the radio non-DSP amp located?

[sodimm]

I searched through the forums and couldn't really find an answer to this. My radio turns on but no sound comes out, so from what I gather, it's either the fuses or the amp. I checked the fuses and they seem OK. I wanted to check the amp.
First question would be, is there an amp in the non-DSP non-NAV radio?
Second is where is it located?


TIA
