Summer Project - Make an INSANELY LOUD Bluetooth Amplifier!

Here's the amp we'll be using Amazon: http://amzn.to/2gNimAD

In this video we'll be making a wireless bluetooth-enabled amplifier so that we can put old bookshelf speakers to good use!
Not only is the sound quality fantastic, but it can also go super loud! It's also quite easy to build, and doesn't require any special tools - you can get away with just a hammer, nail, and a screwdriver if needed. Seriously!

Full parts list (includes international purchasing links):

Happy building!

Oh, by the way, here's the note about the little switches:

These switches change the gain mode of the amp. If they're both on, the amp can reach insane(er) volume levels. However, to hit these volume levels without distortion, the amp needs 25v, which is more than our batteries can provide. The amp is loud enough with them off, and it also means that the signal to noise ratio is MUCH improved, so I don't really recommend messing with them.

This is two years late saying as I just have watched the video, but I can confirm that he isn't lying about the audio. Having watched his portable mic build before this I know he has the audio gear to record at a level that is going to be higher quality then what most peoples headsets and or speakers can reproduce, an added bonus to my claim is I have recreated this genius device and tested it, and it really does work. Keep up the amazing work +DIY Perks

hi how does it charge ? please

Can I just buy it from you lol. I've always wanted that for my stereo speakers.

Mr. Perks,
First off this is an excellent resource for all kinds of out of the box creative projects - I especially love all of the audio related videos! I am trying to see if I could use a set of bookshelf speakers as recording monitors instead of buying expensive ones at the audio store. I realize the sound output would be different and lead to differences in mixing because of the nature of studio monitors, but for my wallet's sake - I thought I would give it a try.
The only problem is see is the latency and signal load created by Bluetooth as well as a lack of Bluetooth output on my audio interface. Can you think of any way to make the connection between the interface and the amp a physical one? Or at least a way to convert 2, 1/4 audio jacks to Bluetooth without loosing too much quality?
Thank you for your help & seemingly endless wisdom!

If I am going to use 2 50w 8ohm speakers and connect them with this amp, how big does my battery pack has to be in Mah?

Thanks for the build, could I add a rotary volume control, if so could I just put it between the amp and speaker?

Quick clarification if I was to buy a 12v 2.1mm jack male power supply and change the male jack to female would that work as a charger for the batteries

Hi, i like this idea of building powerful bluetooth Amplifier & thanks for the video. I would like to know how much volt is required for the Amplifier when both the little switches are in off state? Can you recommend any other battery instead of using AA batteries?? Thanks !

Автор esqueue ( назад)
I like how you said 12 - 15 volts. I was wondering about nimh batteries. I wonder if it would be possible to run 8 Li-ion batteries with 4 in series x 2. That would give 16.8 volts after charging but eventually work it's way down to 14.0 Volts at it's lowest. That or use 6 in a 3 in series x 2 setup that would give 12.6 volts down to 10.5 volts which may be too low.

Not so ecological way to make it... and the worst part of it it's the rubbish piece of chinese little amp used. They can last a playlist or 3 months putting aside the amount of distortion put over those speakers and into your ears!

Автор Jarvie Stenhouse ( назад)
thank god he's getting the subs he deserves ive known about this for almost 2 years and ive only just bought the amp, waiting for it to come

how do you charge the pack, or do you have to remove the batteries and put them on a separate charger?

how do you charge the battery's without removing them ti a charging socket?

Автор Bob Marley ( назад)
Couldn't a 9 volt battery holder be used instead of the big battery holder that you used? I suppose that would cut down size a fair bit :) Or maybe you could tweak it to use 2 of those 9-volts, then it would be even smaller. I'm not sure if 18 volts would be too much no matter what...I'm that much of a handy man xD

For those that think this is a load of wank take a close look at the board. This is a bridge-tied load class D amplifier runs around 90% efficient . Or for the cloth heads Pulse-width modulation. Very real.

I am getting terrible feedback through this board, I suspect it's coming from the bluetooth chip. Did you experience anything like this?

Автор B0M0A0K ( назад)
This is a great tutorial, but I notice that the board your links point to is not the board you are using, the links seem to point to a board that does not include the on/off and aux connector. Has your specific board been discontinued?
