This is another spin-off project from my PowerMac i3 Cube build, inspired by MacTester57's mod. I wanted to keep the stock design of the Pro Speakers cable, but updated with USB and Bluetooth. After researching the best amplifier boards that could be connected with USB and Bluetooth, I ended up on the DW-CT14+ which seemed to have everything I needed for this project. The board is also not too big so I was able to design and 3D print an enclosure that looked like the stock board enclosure. In the end I'm very happy with the way it turned out. It works either with a power bank through Bluetooth or directly through USB and the sound pretty good too!

Test fitting the board in the 3D printed enclosure:

To make the board as flat as possible, I removed the battery and speaker connectors and replaced the capacitor with a new one with long leads. Then I soldered the speaker cables directly to the board. Everything fit nicely inside the enclosure:

The completed enclosure. I made matching vinyl stickers to the stock enclosure:

this looks pretty great- quick question, when you say it works "through Bluetooth or directly through USB", do you mean you can use it as a USB speaker output? Or does it get power via USB and signal only through bluetooth?

thanks!

Thanks! It works like a USB speaker (natively, no drivers needed) and gets its power from USB. So I can directly connect it to any computer or phone (with a type C cable). Or I can power it with a power bank and use it as a Bluetooth speaker. It's a great little board.

Ohhh this is good to know. I’ve got a few sets of those speakers in the attic- time to make them useful again!

sorry for the double post- can I ask where you got your board? I purchased one on Amazon and it's the same board, bu the USB functionality is missing. Bluetooth works just fine, but it doesn't show up anywhere on a computer for USB output.
