Hello all,

No sounds coming out of the speakers since I jumped/replaced the battery. So I started researching for troubleshooting, but none worked, such as

1- Disconnect the battery and connect it back
2- Press the power button for 20 seconds on the radio to rest
3- Inspect the fuses still good
4- I checked/tested one of the speakers, and it worked

I hope anyone can help me with this issue!
Thank you.

Chances are you blew either the AV main fuse, or (if it's Bose) the Bose Amp fuse. Both fuses are in the cabin fusebox at the left end of the dash. If those are good then you probably blew up the amp in your AV Unit. If you held a vote, Bosch AV Units would definitely be deemed "most likely to crap out from a reverse jump".

Thank you for the information
