Bluetooth Vintage Speaker Upgrade




About: I love creating and making things. From leather wallets, wooden rings to DIY projects. I also make videos of everything I make, have a look at my YouTube channel.

In this Instructables I will cover how I upgraded an old vintage speaker to a wireless bluetooth one. It's a very simple project and shouldn't take any longer than an hour, and surprisingly cheap, especially if you already have an old speaker laying around.

Now I am no electrician, and this is my first ever audio project so I am sure from a audiophile point of view I've done is a crime, but it works fine for me, I just use it for Audiobooks & Podcasts, and have another pair of really good speakers for music. I do plan in the future to upgrade the actual speaker inside and put a brand new one in.

For this project you will need;

Step 1: Clean Up

I picked up this super old speaker off eBay quite cheap. I had no idea if it was going to work or not but wanted to do this project for a while and finally just thought I'd take a risk. First thing to do was open up the back and clean it out. There was about 50 years or dust and dirt built up inside so I spent some time cleaning this all out.

Step 2: Wire Up Amp

Next I wired up the amp. This is a super cheap and simple amp that I bought off Amazon for around £10. I first wired up the speaker cable. This amp is designed for stereo speakers so you can wire up a pair if you have them. However as mine was just mono I just wired up the one. Next I put in the power cable and was happy to hear the speaker come to life with the bluetooth connection noise.

I found a 12V 2amp power cable laying around which fit the spec on my instructions. But always read the manual that comes with your amp to make sure you don't break it by plugging in an overpowered plug. Check the photo above to see where I put each cable. I also adjusted the gain settings to the lowest settings as the speaker was more than powerful enough, I also noticed the sound quality wasn't great when at full. I just used a flat head screwdriver to adjust this.

Step 3: Finish

I put a couple of screws in to hold the amp in place. But I will probably put a new speaker inside at a later date to get a better output, and find a better solution to this when I come back round.

I hope you enjoyed this project and hopefully inspires you to dig out those old speakers and bring them back up to 2017!

    Going to try this asap! However, the lights were never discussed again after their introduction. I'm curious as to how to run a light to illuminate the back of my antique radio dial.

    That is super cool! I am definitely going to be trying that..

    So cool. I love these projects that provide maximum joy for relatively little effort. I use the same module but I've been converting 80s boomboxes with varying levels of success :D

    Thats cool :) It's so easy to use the little bluetooth thing. I want to make one from scratch next.
