TDA7294 is a chip amplifier that can produce best bass with high power output. I'm make a bridge of TDA7294 and add a lowpass filter in the input.
The amplifier will shake your room..!

Tda7294 ic nice ic is amp se sound quality jabardast . Cristal sound .bridge mode par 12inch ka sub woofer bhi chala sakte ha 24.0.24 5amp par maja aa Jaye
I have 24-0-24 5 amp Tranfomar and 10" 4 ohms 200watts RMS subwoofer.... This bord support?
sure you can use this amp sir
Is there any substitute for .39uf capacitor
you can use 33n sir
ada kit driver power amplifier rakitan untuk walet ga gan?
Kenapa file nya tidak bisa di buka mas?
ini menggunakan travo berapa ampere mas?

Please
Masih ada pcbnya mas? Kl ada sekalian link olshopnya
Bro subwoofer bord Amazon pe nahi hai7294 ka Stario aplifer hai
Jual pcbnya di tokopedia?
Om stok pcb nya masih ada? Boleh saya beli satu? Atau dua
bisa pesan yg udah jadi om subwoofer nyah
Gan ini pcb nya gak ada di lapak topednya ya.? Pdhl mw order
Nice video
Suaranya jelek amat...
Can't open your circuit file
Harganya brapa bang itu
Bahut acchi sound aaraha he.board ka size kya he ?
Bhai g je amplifier mujhe Lena hai

2x100w
TDA amplifier: heats upto 100°c
PAM amplifier: heats upto 30°
Tda 7294 100watt
PAM .......... Watt sir
lol. u can using heatsink for tda.
Kaise milega je
I think this is 100w rms because tda 7294 has a rms power of 50w . But very nice design and video. Keep it up.
160W pure on bridge mode
@@barlexrespectaizer452 how 50+50 is 100w i like your chanel but i dont agrre this . I sarch for it. Thx for the response.
why you not agree, this is from datasheet
BRIDGE APPLICATION
Another application suggestion is the BRIDGE
configuration, where two TDA7294 are used, as
shown by the schematic diagram of figure 25.
In this application, the value of the load must not
be lower than 8 Ohm for dissipation and current
capability reasons.
A suitable field of application includes HI-FI/TV
subwoofers realizations.
The main advantages offered by this solution are:
- High power performances with limited supply
voltage level.
- Considerably high output power even with high
load values (i.e. 16 Ohm).
The characteristics shown by figures 27 and 28,
measured with loads respectively 8 Ohm and 16
Ohm.
With Rl= 8 Ohm, Vs = ±25V the maximum output
power obtainable is 150 W, while with Rl=16
Ohm, Vs = ±35V the maximum Pout is 170 W.
@@barlexrespectaizer452 it can be becouse of the small power loss on the d mos s . I se a max of 140w at 45vx2
Bos pesen satu kit subwoofer yg aktif yg bisa angkat speaker sub10/12 inc
cek di toped barlex audio gan
Ok gan
Big fan of your work.
Sir how will I add frequency control to these circuit
if you need to build a preamp with freq control you can use this gerber or schematic link below sir :

Tnx u so much u r a good TH-camr God bless u
Is It 4ohm Stable? And if so.. what is the output power at 4ohm load?
on datasheet 8ohm about 150W in bridge mode. may be about 170w at 4ohm
@@barlexrespectaizer452 Thanks For your reply. Acctually iam Confused cause in datasheet its says in bridge mode 170 watt at 16ohm.. how is it possible cause the impedance will be so high..
Use it on 16 ohom 35-0-35 volt 3 amp You'll get very low distortion and 170 watt
Kalau buat angkat Cello 8Inch 500W maksimal gak ya om..?
Horeg,...top
Hi sir I am purchase PCB please rate and contact
Is there any another resistor instead of 330k .
that's gain resistor, if your input signal weak you can change with more than 330k, like 390k but if your input signal strong you can use 100k or 220k resistor
I have 390k resistor can I use it
@@gokulg264 sure
Tnx sir u r great
how much is the Stand by power supply?
Or to which pin does the 20k residence stand-by enter?
Het how about a stereo one!...no bridge!..
Berapa range frekuensinya om?
Mujhe 7294 circuit board de sakte hain
Missing some components list in this video
This circuit suitable for 10 inch subwoofers..
Olá.. como faço para comprar essa placa..??
Ai serkit bord ki kora pabo
Please share the components list
Can I use 8ohm 200w speaker
sure...
Wah mantap 👍
Kalau tda 2050 bisa di buat sub gak bos
If I used 30-0-30v 5A supply then how much watt will I get in output
about 200watt output from the transformer.. but it will be very hot
Can I use ne5532 ic will it give best result
sure..
Yg tda 7379 gk ada bang 🤤
Chinese ic works?
Gan untuk angkat speaker sub. Legacy 6"X 2 udah max belum suaranya?
bisa.. main 4 ohm
Can 7296 be installed instead of 7294?
Yes but 7296 only 60W and using 70 V power. So you need to change capacitors to 3300 mF 50V.Even 7293 better but 7294 is the best 100W TDA amplifier 😉
Mas bro boleh tau bentuk dan ukuran box subnya yg ini ?
Atau sdh ada videonya, klo sdh ada videonya sy minta linknya lah. Terima kasih 😁
ooh itu bagian bawah dari spk white coffee
th-cam.com/video/iPzGw-3uJYw/w-d-xo.html
Can I use 22k instead of 20k and 33k instead of 30k resistor
sure, no problem
Can I use 100k potentiometer instead of 50k
yes for this circuit,
Bhai 1 banake deskte ho....
Sir 18-CT-18
CT Meaning? And Transformer Ampere For Comfortable This Circuit?
it means 18-0-18 transformer.
you can use 5-10Ampere transformer sir.
@@barlexrespectaizer452 thnxx sir
How much price bro
How to get above 100w from these circuit
use more current or voltage on the supply.. or you can try to paralel the output sir
100nf capacitor and 470nf capacitor how many volts bro please tell me please
all MKM capacitor maximum 100V brother
Thank you bro
plzzz upload the pdf file ....... thanks
On the description find schematics link, there is some pdf file
Bisa untuk ampli subwofer di mobil gak gan?
mesti pakai inverter lagi gan
Wihh sangar cah PCB.ne 👍
ia nih hehe harus semangat..
A sekit bord kaise paiea
transformer information plz
18V CT / 10 Ampere.
You can up to 24V CT but you need more heatsink.
apa nama aplikasi disgn pcb nya bang
saya pakai diptrace
@@barlexrespectaizer452 beli komponen nya di mana bang?
How many inch subwoofer connect
8-12" still good sir
For best performance do I have to change 2200mfd with 4700mfd or higher mfd
for power supply ? sure...
@@barlexrespectaizer452 yes

Mas apa amplifier itu bisa di pasang ke speaker bazooka 6" x 2 psw 500? Saya bantu subscribe mas😊
bisa, tapi kabel +/- speakernya jangan sampai kebalik, soalnya system box nya isobaric
@@barlexrespectaizer452 siap mas terimakasih banyak
Sub impedence shold be 8 to 16 ohm in brdge mode? Will it owrk on 4ohm?
work, but more big THD
@@barlexrespectaizer452 as per data sheet in bridge mode 16 ohm is recommended +_25 vdc 8 ohm recommended
What will u suggest?
Can i use 8 inch speaker
Can i use 8-12 inch speaker as subwoofer will it decrease the bass intensity when increase the size of speaker
yes, but the watt of speaker smaller than 300watt
How about when I connect with 30-0-30v 5A

Mantuuul gaeeees
Pcb size please tell me bro
8.5 x 5.5cm
· Sir In this circuit you change the value of some component and tell you I want to run this circuit on 24 0 24 supply so that you tell the component. Use them or use PCB containing please tell me I am wating
no problem sir, you can use 24-0-24 transformer. But don't forget to use big heatsink on it. by the way use the 50v elco on the supply. I'm use 18-0-18 because very difficult to find a original ics in here
Barlex respectaizer ok sir· Sir, I did not even get the IC, I got tired of walking around
Barlex respectaizer thanks sir
Punya saya beli kit di agan.. Trus saya geber, panas bgt.. Apakah wajar
wajar, TDA7294 memang sangat panas gan.. yg penting kasih pendingin tebal dan pasta nya biar awet
Di kasih tegangan 25vac, mampu ga gan, ic nya
mampu kalau asli

Can i use this amplifier for my infinity primus 12" car audio subwoofer. Is there any problem while bridged amplifier connecting with 4 ohm driver ?
please om pake bhs indo saja..... bahasa inggrisnya anu banget soalnya xixixi
saya juga sebenarnya gak mau pakai ingris, tapi supaya bisa kerjasama PCB nya, ya saya mesti ingris
Padahal saya juga lebih suka pakai bhs indonesia loohh
Hadeww,,,,gan kalo agan pakai bhs english ,,,agan seperti jarang omong,,mendingan pakai indo aja gan biar bnyak omong
Intinya ini semua demi kemajuan channel kita ini ya agan agan.. demi kreatifitas dan berkembangnya channel ini.. nanti akan ada juga kok video pakai bhs indo.. btw beberapa video udah dibuat subtitle nya..salam sukses selalu..
