Z5500 amplifier swap

The problem

A friend lost functionality of the head unit for the Z-5500 setup

Simplest plan was transplanting the amp for a subwoofer kit and then connect the satellites to a home theater receiver, thus a 5.1 system is complete.

Blue smoke release point

There is no point attempting to repair the board since I do
not have acces to schematics, the PCB for the supply might not be the only broken part.

 

Teardown

There's no fancy procedure to dissasembly, just remove all the screws and tear out the guts.

The power and fuse connectors are glued, not bothering with them.

Adding a new amplifier

Fosi, ZK-502C, BT integrated class D.
