Outstanding video my man. Too many video's on youtube are just musical mysteries, your commentary, careful instruction and demoing the results sets this video far above most of them. GJ man.

[@TrapShooter68]

It's great to see someone build something that doesn't cost hundreds and require thousands of dollars in tools. Great job!

[@itsJWPH]

Simply put, straight to the point, no DLCs included. Kudos from the Philippines!

[@javi8799]

Thanks man, i was getting crazy figuring out why my speaker was shutting off, even using two LiPo batteries in parallel which cover the power demand by far. I have to admit that you know what you're dealing with, i'm studying electronic engineering and never had the idea that the cables i was using could affect that much to my problem (they were basically aluminium junk from an USB). Thanks for those good explanations, you have a new subscriber.

[@niklaslins99]

Wow, this is by far the best tutorial i have ever seen! :)

[@biplabganguly]

Very educative and descriptive video, really explained everything from start to finish. Thank you Sorin , it helped me a lot, soon I shall build my own.

I love projects like this, sure you can go buy one for less cost, but what fun is that. I would rather spend a little more, make it myself, and learn. Well done.

[@Kenhenderson97]

You are a good teacher Sorin. You should be inducted into the Nerd Hall of Fame!

[@TheDradge]

Another good video and good advice. But do remember that if someone has a bunch of 4 ohm speakers, it's possible to put them in series to get 8 ohms. All is not lost! Also, a tip: soldering 2-3 inches of wire to the Bluetooth F-antenna will remove a lot of noise at low volumes. In my experience those PCB antenna always work better with extra wire soldered to the end of the F.

[@Sorin_DIY]

hi. if you connect 2x 4ohm speaker drivers in series, you can use them as a 8ohm speaker. but there is a small problem: the voice coil of one speaker driver will become a small frequency filter for the other speaker connected in series. so both speakers will lose some of the high frequency sound. if you do this with bass speakers it's ok. but if you connect tweeters (with voice coils) in series, you will partially cancel their ability to make high frequency sounds.

[@santoshwhy2943]

Very nicely and well explained each and everything 👍 great job brother . It might not look good for some people but it sounds really great.

[@strugglingparodox5709]

Very nice, and simplistic in its oporation. Bet it still sounds pretty good, even if it wasn't built to the size of a small suitcase.

[@charlesdeens8927]

Nice project. You should of used a textured paint for your enclosure. That particle board has way too many imperfections, that a flat paint will reveal. A textured paint would hide all those imperfections and give a much better look.

[@udaypatil1992]

Good speakers i love it It doesnt like other speakers it is very powerful

[@muizenissen]

@Sorin: a practical tip: at timestamp 6:03, you're cutting into the board with your arm in front of the saw. If the saw runs off without resistance after cutting the last millimeters of board, it may overshoot, and you may cut half your arm off. Never cut into your own limbs/fingers, always cut away. If you don't have clamps to hold the board to the table, sit on it with your knee, and catch the falling part with your free hand. NEVER hold it in the way you do here. One accident may scar you for life. Also, jigsaws can cut fairly straight, if you use a guide. Use a straight bit of metal/wood, about 1cm thick, and place it so that the base of the jigsaw slides along it.

[@steavekamei2013]

Sir how to solder multi colour led?i have tp4056 module and i want to replace led like you tel me

[@Sorin_DIY]

you need a multi color LED with a common anode (or positive). on the tp4056 board the 2 LEDs are soldered with the anode side by side. so you solder the anode wire in the middle, between the LEDs. in my video the anode is yellow and the cathodes for the 2 colors are red and blue.

[@steavekamei2013]

I got you... thanks soo much for your help

I used 10W 40hm speaker when I connect both the speaker bluetooth not connected in my mobile , if I remove any one speaker connecting also Bluetooth.amplifier shutdown down when increased volume Is there any possible way for 4ohm 10w speaker?

[@vijeandran]

Hi Sorin, This brand speaker is not available in my town. What speaker I can choose? Will i get same type of speaker in other brand? Or tell me alternate speaker model ?

[@Sorin_DIY]

hi. you can use other type of speaker drivers. dayton speakers are very good, but expensive. I suggest you find 8ohm speakers, with a diameter of 6cm or bigger (mine are 7.5cm), with rubber surround.

[@TheHitcheroo]

Hello Sorin. Great speaker. Do you know if there is a easy way to integrate an Aux input into the circuit?

[@Sorin_DIY]

hi. for this bluetooth module we cannot add aux in. but in the future I will make a bigger boombox with more features, including aux in.

[@gabrielantiligando9905]

Thank you for telling me about that amp. I made also a bt speaker with a different amp. A 2*30 Pam8610

[@electronic7979]

Excellent video

[@gepisar]

is it possible to split this box? i.i make a "left" and "right" separate speaker that i can place optimally, but that they are synched to the same single Bluetooth source (phone)

[@Sorin_DIY]

yes, it will sound even better.

[@lee26carl]

Nice. I love it

[@jasonhernandez6291]

Can this battery pack be used on any size speakers I was wanted to use 2 10in speakers and 2 tweeters?

[@Sorin_DIY]

the battery pack is suitable for this bluetooth amplifier. the speaker drivers also need to be suitable for this amplifier. if you want to use 4 speaker drivers, 2 for bass and 2 for treble, you need to add a crossover filter on each channel, and the speaker drivers need to have 8ohms. but if the speaker drivers are too big, the amplifier will not have enough power to work with them.

[@ketalix]

Hey, thanks for the video.I liked. Just a noob question....can i do the same with 2x Efest 18650 battery 3000mAh 35A 3.7?

[@Sorin_DIY]

yes

[@vijeandran]

Hi Sorin, i finished making of this bluetooth amplifier and Working fine but Whenever i increase the volume, the bluetooth shuts down. It is annoying. my speakers are 8ohms 30watts speakers each. two 2500mAh 18650 batteries used. Voltage set to 5.2 volts. the wires that i used are bread board wires. What is the reason for this bluetooth shut down? How can i rectify this?

[@Sorin_DIY]

hi. breadboard wires are thin. try with other thick wires. use thick short (max a few cm) wires for all the supply wires.

[@vlatko1denkovski]

Great video. You motivated me do make one for my self. I have a problem with mine tho. I use a similar setup except I use separate bluetooth module with a 3w amp and have yet to buy the capacitor. When I power it on it shuts off after 2 seconds and it goes in a boot loop. Any idea how to fix the problem?

[@Sorin_DIY]

hi. did you fix the problem? do you have 4 or 8 ohm speakers? what power source did you use. I suggest to try it with 8 ohm speakers and separate power supplies for each module, with minimum 1A.

[@vlatko1denkovski]

Thank you for the reply. I am using 3w 4 ohm speakers connected to PAM 8403 which is powered with two 18650 batteries connected in parallel. I have TP4056 charging module with protection and 2 amp boost converter. Without the boost converter is working fine, only problem is my 5v bluetooth module, I don't know if it will work with lower voltages as the battery drains. Separate power supplies cause a horrible ground loop which distorts the sound, I have tried that.

[@diyhemantprojects2841]

I want to know which amplifier is best according to you as far now I saw 3 videos of 3 different amplifiers which one should i use.

[@Sorin_DIY]

hi. it depends where you want to use it. all 3 are good amplifiers. in my opinion the best one is pam8610. because it's very powerful and it needs very little current. I will use it again in a future video, in a more complex project.

[@ogdan1173]

Succes în continuare . Am şi eu un pistol de lipit românesc .

[@gastonbriceno247]

Excelent and well talked trhough tutorial! Do you think that i can use 40watts 8ohms speakers with your configuration? Should i use mor than 2 cells? Thanks in advance

[@Sorin_DIY]

hi. you can use the speaker drivers, if they are good quality ones. 2 cells are enough. the autonomy is more than 10 hours at maximum volume with 2x 2000mAh cells. if you use 2600 - 3000 mAh cells it will last even longer.

[@gastonbriceno247]

@@Sorin_DIY Thanks and yer they are good car speakers. Excellent i'll use 2 cells then. Thank you very much!!

[@yernickle]

Nice camera work

[@vijeandran]

Can i know the reason, why r u soldering two batteries instead of using battery holder?

[@Sorin_DIY]

hi. the battery holders will work too. but the connection is much stable with soldered terminals. in time the holder contacts can oxidize and you will lose power. the battery holders are useful if you intend to remove/replace the batteries often, which I won't do. also the holders will increase the overall project price.

Nice video. everything is fine and good. but u did not tell about the position of small switch embedded in the amplifier board.

[@Sorin_DIY]

hi. I forgot about the tiny switch. it switches between battery or micro USB use. I set it to be powered only by the USB port.

[@3rutu5]

great work, amazing what you could do with two hands.....next time you could consider having a few different grades of sandpaper and use a scrap piece of timber as a block and sand until you get that smooth finish. that and a bit of wood filler and i would say you would be hard pressed to notice the difference between power tools and manuel labour. I've really enjoyed doing it. loved the video and look forward to more :)

[@denyk61]

I'm also use this bord (hf61b )when I increase volume the bord switch of automatically and start please help me and same solution

[@Sorin_DIY]

hi. did you tried everything I said in the video? use short thick wires on all the connections, good li-ion cell(s), separate step up converter, 8 ohm speaker drivers (not 4ohm) ?

[@wanderer4959]

Excellent explanation. What type of wire r u using for the conection? Any particular name for the wire?

[@Sorin_DIY]

hi. in general I use wires salvaged from PC power supplies. most of them have good quality thick wires. they also have a lot of colors to choose from.

[@mediappak9046]

i like that,thank for sharing.

[@vimcbe]

Hello sorin.. your work is amazing, especially the way you explained. I've a small question.. what's the capacitor uf value and volt that you soldered directly in DC stepup module ?

[@Sorin_DIY]

hi. I think it's 2200uF at 16V. you need a capacitor with a rated voltage higher than the running voltage. so for a 5V device, you need a capacitor of minimum 10V. there are also 6.3V capacitors, but they are too close to the running voltage. the capacitance depends on the supply power and the load. for a 5V bluetooth speaker 1000 - 3300uF should be enough.
