You know a lot about electronic stuff, as I've seen in your other videos already. Excellent to mention the correct phase alignment of the speakers. It's something other builders of speakers don't bother to mention. Nevertheless, it's important. I also like your way of thinking regarding the cooling of the amplifier. Even if it is a box...you showed some "out of the box" thinking in this project. This has got to be the cheapest, yet good portable speaker build I've seen in here.
Same for me, so much info great info shared in this video, even if you dont plan to do exactly the same speaker, a lot of idea and mistakes to avoid when working with Audio and Power!!
Hi Sorin. The line of pam amps are pretty impressive, I've built a few projects with the different chipsets, and all have worked out well. I've been watching a bunch of home made Bluetooth speaker builds lately, and I must say, the few speaker builds I've seen of yours have been the better ones. You have a good understanding, of how best to utilize speaker drivers that other people wouldn't care to use. You also seem to understand, that no every portable speaker has to fit in your pocket, having to use tiny drivers, but crammed to capacity with batteries and other components. I like the way you keep these home builds simple, and effective. (Not to mention) using salvaged parts to repurpose them. Thanks for making interesting informative videos. Oh yeah,,, rules of cats,,,,, they MUST investigate speaker boxes.
Imi place ca abia mi-am dat seama ca ai vorbit romana la inceput :)) fain (de acum, o sa comentez in engleza aproape tot timpul sa inteleaga si cei care nu sunt din Romania)
Great project as always! Full of info and mistakes to avoid when building homemade Speaker!! I liked the Audio knowledge shared and also about the battery/ 18650 pack. By far the best Audio Build around on RUclips, everything is not about the esthetic, but more about the knowledge shared through the whole video!! Keep the great your work!! PS: I would have spray painted the case in black, but it seems that you are fine with the laminate wood color :P
Proiectul este foarte bine explicat, componentele sunt best buy la pretul asta, cat despre video... Dureaza 13:37 minute :)). Meriti mult mai multi subscriberi decat ai! Succes! ;)
Scosche car door speakers are much cheaper too I also would highly recommend sony car door speakers or scosche car door speakers from Walmart if your gonna use speakers for that project
Nice work, for easier battery management use a DC/DC buck boost module ~$1 and a USB 18650 charger protection board ~$1 with multiple 18650 cells in parallel, use the DC/DC buck boost module to bring the voltage up to a constant 9 or 12v or get a lower voltage amplifier and better yet one with built in bluetooth.
hi. thanks for the feedback. that will work too. but you will loose some power, because the step up converter efficiency is not 100%. usually this method is used for low voltage amplifiers 5 - 6V. you can get 12-15V from one or more 18650 cells connected in parallel, but when the battery voltage drops lower than 3V, it will be difficult for the step up converter to get it up to 12V and 1A. the efficiency will decrease to 70% or even less. you will loose a lot of battery power. the charger will also need to be very powerful. for example to get 12V 1A from 5V at an efficiency ~80% you will have 12V*1A=12W; 12W/5V=2.4A; 2.4A/0.8 (80%eff)=3A. you need a 5V and 3A charger. step up converters are useful only for low power amplifiers. I've made a 2x6W bluetooth amplifier with this configuration and it works great. but for powerful amplifiers you need a 2A or more, constant power source.
How about including a solar Pannel and charging circuit, Bluetooth and wifi would make it a wee beasty, fab simple easy to follow vid, love the calculations and examples. Cheers
Hello sir, thank you for this wonderful project! During 6:44, what are the directions of the red and green wires on the jack? Right or left? Maybe you explained it in the video but I cannot hear the video, that is why I am making a DIY speaker :) Thanks!
hi. the colors don't matter. the tip of the jack is the left channel, the middle (ring) is the right channel and the base (sleeve) is the ground. you can connect all the components and then use an app on your phone, or the sound settings on a PC sound board, to check if you connected correctly the left and right channel. if the channels are not connected correctly left and right, just reverse the wires for audio left and right where it's easier, on the audio jack, potentiometer or the amplifier audio input.
@@Sorin_DIY Thank you so much! Because I was using a female socket before the jack, I asked you which color is left or right channel. Finally, I found the wiring diagram of the pot on the internet and connected right cables :)
is there any noise on sound and is there any background noise without playing anything or is there any amplifier with Bluetooth chip integer that you recommended with to the people who has more budget
hi. there is a small background noise, when the audio jack is not connected to anything, or when the jack is connected to the phone and there is no music playing. but this is common to almost all amplifier boards. I've installed the volume potentiometer to my speaker, so you can just turn it down, when you don't use the speaker, or when you unplug the cable, so you don't hear the noise. the amplifiers with audio bluetooth receiver included have an auto-mute function, when the bluetooth doesn't receive any music. that's why they don't have background noise. but is the same as turning the volume potentiometer down. I will test more bluetooth amplifiers in the future, to see which ones are better.
Good morning. Awesome explanation and thanks for the vdo. If I want to buy this speaker from the speaker shop what is the Watts, Ohms and diameter of the speaker I have ro ask ?
Nice build but i m having doubt for the battery run time as you said run time is of 10hrs for 2000mah which means it will consume about 200ma at 12 volt and it means power output should be of 2.4 watts and you are saying it as it is providing 30 watts
hi. the current consumption of an audio amplifier fluctuate. it depends on what kind of music you are playing, songs with powerful bass sounds drain the battery faster, so it may last less than 10h. also the current consumption is much lower, it's not 30W continuously. the average current consumption is much lower and the peak power is 30W, for seconds or fraction of seconds, for example when there are bass sounds during a song. if you play only bass test songs, the battery will probably last only 2h. and the last thing, the power of audio amplifiers is exaggerated by the manufacturers, to sell their products more easily. in reality it most likely has less than 30W. so this audio amplifier has a maximum (not continuously) output power of almost (exaggerated) 30W, depending on the song frequency and volume level.
I recently bought a Tda7492P amp board. I would like to make a Portable Bluetooth Speaker. Can you recommend how I can run it off 18650 batteries? Should I run them in a series? It says it can 8-25V in the details of the amplifier. Do I require a step up module? Thanks in advance. Tim
hi. you need a 5S battery pack, which will have between 21V fully charged and 14V fully discharged. for this battery pack you need a 5S BMS with balance and a 21V 2A charger. then you have 2 options: 1) to use the battery as it is and the voltage will decrease, while the battery is getting low, so the amplifier will have less and less power, until the battery is discharged. 2) use a step up converter, to increase the battery pack voltage from 14 - 21V, so the amplifier will always be powered with 25V. this way the amplifier will always deliver the maximum output power. but the battery will discharge much faster. because you will always get the maximum power from the battery pack, even when it's almost discharged. and the step up converter will work with an efficiency of 80-90%, so you will lose 10-20% of the battery capacity, just to run the step up converter.
Hi sorin, nice video. Thanks. I have a Bluetooth speaker. Its 2×3watt speaker, but in full volume the sound is distorted or crackled. By adding PAM8403 amplifier, can it be fixed? Please guide me.
hi. it depends on where this problem is. the lithium cell may not be good enough. you can try with a better cell. you can try to add a smoothing capacitor on the step up converter output (if there is a step up converter) or on the amplifier power input. are the speaker drivers pushed to the limit when the sound is distorted? in this case you need better speaker drivers. first you need to find the reason for the distorted sound.
very nice video. Can I use 4700uF 25V capacitor and if I want to use 2 PAM8610 kit with 4 Speakers the do I have to use 2 BMS module to give them individual supply Also the 4.7Kohm resistor of how much watt You are using a Speaker of 100W. the amplifier support 15W
hi. yes you can use a 4700uF 25V capacitor. you don't need 2 BMS boards for 2 amplifier modules. the BMS board is to protect the battery pack, you can connect 2 amplifier modules to a BMS. the speaker drivers should have a higher rms power than the maximum power of the amplifier.
Hi Sorin, thx ur projects are always so great, still waiting for the Variable voltage Power Supply. I plan to use the same protection board as you, the 3S Battery protection board, but how to know when to remove the power cable from the created project?? I mean for the TP4056, there are 2 leds, one for charging and another when the bat is full, so it can be disconnected. what about 3S proctection board??
hi. some protection boards have LEDs to show when the cells are getting charged. this one does not, so we don't know.. it takes 3-4 hours to charge the 2000mAh battery pack. you can use a voltmeter/ammeter, like I did in my cordless drill conversion video. when the charging current drops to "0", the cells are fully charged.
@@Sorin_DIY thx, and effectively I am getting exactly the same 3S board, so without any Led to indicated when the charging prossess is done. I ll look to the cordless drill project for more info. is there any risk if I leave the pack charging, since the protection 3S board is there to cut the charging??
hi. you can leave the charger connected, even if the cells are charged. the protection board will stop the charging and the speaker will work on charger power.
the supply power is ok. you probably use 4ohm speakers. if you use 2 or more speakers in parallel, they will make a lower impedance and this could damage the amplifier. you need to use 2x 8ohm speakers for this amplifier. or if you use 2x 4ohm speakers, you need to add a heatsink on the PAM8160 IC.
I have some doubts , Please answer them if u can. I use 30 watts 4 ohm speaker and the board heats a lot , do i need to attach a 4 ohm resistor in series ?Why did u give the speakers separate Chambers?
hi. I suggest you use 8 ohm speakers. if you 4 ohm speakers, you need to power the amplifier board with max 12V (not 15V which is the maximum voltage for this board) and you need to add a heatsink on the PAM8610 IC. you can add resistors in series with the speaker driver if you want, but they will get very hot and a part of the energy from the battery will be wasted on the resistors, it will be converted into heat. the speaker drivers enclosures are separated because this is a stereo speaker. that means one speaker can make different sounds than the other, they can vibrate differently and they must not influence each other
hi. I didn't save the links, so it took me a while to find them. ruclips.net/video/-7fuHEEmEjs/видео.html ruclips.net/video/V42iRj0Toq0/видео.html ruclips.net/video/yJg-Y5byMMw/видео.html ruclips.net/video/C6IaUMAg3Dc/видео.html
Hi Sorin. Can you please check the amplifier sound with low volume? I bought already several amps with this chipset and all of them distort at low volume. On medium to high volume they are ok. Mulțumesc!
hi. my speaker sounds ok. but it depends what power supply are you using and what other modules or audio devices is connected to. maybe you have ground loop noise.
hi Joe. MDF is actually better than what I used. it creates a better resonance, because unlike laminate wood sheets, it doesn't have flat plastic surfaces, which creates echo inside the speaker box. MDF can absorb sound a little better. for this speaker size you can use 8 - 12 mm MDF.
there are a lot of parameters, but the simplest way is to make a copper coil on an ferrite rod, with a few tens of turns. more turns = more filtering. you can get a ferrite rod from old radio units, or from small transformers. if you don't have a ferrite rod, you can make the coil without it, but it will be less efficient. the coil will need a lot more turns. you connect the coil in series with the bass speaker.
Great work, thanks for sharing, What is the size of that small heatzink for the chip or Where can i find that?! Do i need special adhesive for that or a simple super glue will work?!
A problem coming while connecting this board to my speakers sound comes for 1-2 seconds and stops whenever I try to give supply to the board it play audio for 1-2 second only, I try with both battery and adopter, can you suggest me something what should I do
I never had this problem. usually I order 2 or more pieces, if one is faulty, I test the other. yours probably has a problem. what voltage and what speaker drivers did you used? try it with 12V and 2A and with 8ohm speaker drivers. when it stops it probably goes into a protection mode. but what protection...? over voltage, under voltage, over temperature, overload.... it may have a faulty sensor.
This is by far the most in depth but easy to follow tutorial on this project
But I don't have thermal paste how to apply heatsink without thermal paste
Really nice build. You did a lot of things *right* to get the most out of this. Separate ported chambers with opposing ports was genius.
When that bass dropped, I got back the bass my headphones lacked! Thanks Sorin.

hi Joe. MDF is actually better than what I used. it creates a better resonance, because unlike laminate wood sheets, it doesn't have flat plastic surfaces, which creates echo inside the speaker box. MDF can absorb sound a little better. for this speaker size you can use 8 - 12 mm MDF.
@@Sorin_DIY sorry pressed the wrong button lost my comment what was thanks very much now as an octogenarian looking forward to starting
Sir i have a question i search online about those speaker and it was 120 watts and the board was 15 watts max, would it be sound less?
these are some cheap speaker drivers, the rated power is not real. they work well with 15W - 30W amplifiers.
If I want to get only bass from one channel, so what can I do ?? Do I need to make any low pass filter in the output channel ?? Please reply.
yes, you need a filter for the bass speaker driver.
@@Sorin_DIY how to make a filter for 3 inch 15 watt subwoofer ?
there are a lot of parameters, but the simplest way is to make a copper coil on an ferrite rod, with a few tens of turns. more turns = more filtering. you can get a ferrite rod from old radio units, or from small transformers. if you don't have a ferrite rod, you can make the coil without it, but it will be less efficient. the coil will need a lot more turns. you connect the coil in series with the bass speaker.
Really good.
Great work, thanks for sharing,
What is the size of that small heatzink for the chip or Where can i find that?!
Do i need special adhesive for that or a simple super glue will work?!
hi. 8x8x4mm. usually it has a self adhesive pad. if not, you need thermal adhesive.
@@Sorin_DIY thank you very much
A problem coming while connecting this board to my speakers sound comes for 1-2 seconds and stops whenever I try to give supply to the board it play audio for 1-2 second only, I try with both battery and adopter, can you suggest me something what should I do
I never had this problem. usually I order 2 or more pieces, if one is faulty, I test the other. yours probably has a problem. what voltage and what speaker drivers did you used? try it with 12V and 2A and with 8ohm speaker drivers. when it stops it probably goes into a protection mode. but what protection...? over voltage, under voltage, over temperature, overload.... it may have a faulty sensor.
amplifier keeps shutting down when raising volume. any suggestions ?
Hi Sorin the bms board does it have overcharge protection?
yes.
