Dear All,
I am considering building LM3886 based chipamp for my 2.1 speaker system (2x40W 8ohm L/R + 75W 4ohm sub). Though I have never built an amp for a stereo system with subwoofer before. It is unclear for me how the general layout should look like.
I can think of two possible layouts:
What are the advantages/disadvantages of one layout versus another?

I can think of two possible layouts:
- Crossover and 3 LM3886 modules in a single box, sharing one power supply unit.
- Crossover and 2 LM3886 modules in an amp box + separate LM3886 module with its own power supply unit built into/next to a subwoofer.
What are the advantages/disadvantages of one layout versus another?
