No Audio Issue on CR220

[RKPorsche]

I have issue with CR220 on 2002  Porsche Boxster Base, it didn't power on at first so here is the progress I made sofar

 

- Read the blogs/youtube and removed the radio after purchasing the radio removal tool from Walmart (~$6)

- Found the fuse behind the radio was blown (10Amp), replaced it with one from local auto store

- now the radio is ON but prompting for **CODE**, thanks to Renntech got the code to unlock it

- Entered the CODE now the radio seems to be working but NO audio !!!

- Looked at the service manual and fuse details since some of the blogs pointed me to fuse box and the fuse for the AMP. 

- The 7.5Amp fuse was blown on the fuse box ROW D and Number 9 (D9). So while I am waiting for the fuse to arrive (from amazon) I - - had a 15AMP fuse handy and tried to insert it but there was a spar when I tried to do that !!!, guessing a short to the ground some where down the wires.

- So started to remove Audio related modules from the front of the trunk. And found two Bose modules one seems to be the AMP big black casing with lot of vent holes. And there is another module don't know what it is. After I disconnected the wiring connectors from these modules I was able to insert the D9 fuse in the fuse box. So I am guessing there is something is wrong with the AMP or the other Bose module.

 

Did you see similar problem ? What are these two modules for ? there 3 connectors going to these two modules. Any ideas on how to fix it or get it repaired (i don't know which one of these two has the issue or short)

Replacing fuse behind the radio and DSP audio fuse in the fuse box fixed my issue.
