Greetings

You have made a request to make two separate projects.

1. Subwoofer

2. Amplifier

There is lots of information in diyaudio for both projects.

Search and read, then think about what you want to end up with and what you have to work with.

Learn well.

transformer is good for audio,best THD but too heavy
smps are smaller and Popular in Consumer products but have more niose and Handle with care!
