Hey everyone,

I have a set of old but high-quality speakers that I'd love to convert into Bluetooth speakers so I can stream music from my phone or laptop. I’ve seen a few different methods online, but I’m not sure which one is the best in terms of sound quality, ease of setup, and cost-effectiveness.

I'm looking for advice from anyone who’s tried converting their speakers to Bluetooth. What’s the best method in your experience? Are there any specific products you’d recommend? Also, if there are any potential pitfalls I should be aware of, please let me know.

First of all check what's the specifications of your speckers
Watt, ohm etc. Then it's easy for you to check which amplifier is suitable for your need (only

Hello guys, even I wanted to make my speaker a bluetooth operated one, but there are certain challenges that i am facing:
My amplifier operates at 12v and I don't have a battery to provide it constant 12v.
Even if i manage to provide it power through a battery, how would i be able to charge it when it is drained, and how to know when it drains?
If anyone has previously made a speaker on their own, please help me out, Thanks!!!

Hey! I totally understand what you are going through since I have also gone through the same problem when I converted my regular speaker into a Bluetooth operating. I have successfully converted my normal speaker into a bluetooth speaker. First was finding a constant 12V power supply for the amplifier. I choose 12V Li-ion battery packs since they are compact and easy to use, plus each has built-in protection circuits that prevent over discharge, thus protecting the battery and the amplifier. Directly adding the charge port to the speaker box allow charging of the battery without having to constantly open up the speaker. But you'd find it very easily, 12V smart battery chargers, which will charge your battery and automatically stop when it's full. My charger has this indicator light so it'll turn green when the battery is already full-that's super convenient. To know when the battery's on its way to draining, I installed a small voltage meter display inside the speaker. These are pretty cheap and easy to mount onto the casing. It gives a reading of the battery voltage in real time, so you know when to recharge it. I put a bluetooth receiver module connected to the amplifier to make it Bluetooth operated. It did require some planning, but I was able to successfully come up with a fully portable and rechargeable Bluetooth speaker, and it has been working great.
