HI everyone! Thank you so much for tuning in with me on this build! Before we jump in the details, please consider voting for this Instructable in the contest at the very bottom of the page. Support is highly appreciated!

It has been a few years since I started building various portable Bluetooth speakers and boomboxes and even though it is truly satisfying to design and build your own portable speaker - one thing that I noticed for sure is that it does take quite a lot of time, usually a few weekends to build a decent speaker. Therefore I thought I would rather use an already built commercial speaker and attach a "rechargeable amplifier" to it! Not only is it much less time consuming but also a lot cheaper since you can get great quality second-hand speakers really cheap!

This idea of giving old items a brand new life has been with me for quite a while. Therefore I thought to give this old speaker built in the 80's a new life by converting it into a portable Bluetooth + WiFi boombox using the amazing Up2stream Pro audio receiver which can connect to your streaming device via WiFi or Bluetooth 5.0 and with its own app it is a breeze to use. I hope you will give this build a try yourself!

Thank you so much for watching!
