First DIY amp build. Got four NC500MP modules, planning two put into a box: https://uk.farnell.com/metcase/m550...250mm/dp/1510826?CMP=e-email-sys-orderack-GLB (for a total of two boxes). Also planning to design a pcb (block diagram attached) to perform auto signal sense, and mute on startup, 12V IO. What do you think? Any tips of advice? Thanks.
