So, it is a 2-channel (stereo) amplifier with 4 parallel outputs. (channels of amplification). The problems I have with the circuit are the following: No fuse on secondary or primary transformer side. No chassis ground connection. No proper stretch relief on the mains cable. No protection against chafing from the chassis metal on the mains cable. The lack of fusing is the most serious problem.
Nice video, but this not a surround sound amplifier, the 5.1 decoder is missing, also using the 5 v supply from the same transformer output will give a beeping sound for the BT.
its a 4 multi chanel stereo Amplifier, for 5.1, you need a circuit that makes a 5.1 division at stereo signal, or a digital processor that have 5 +1 outputs
do you know what (5.1) surround system is ? you have made amp but it will work as stereo. 1). you haven't install any any any low frequency filter for sub. 2). you have no option to give 5.1 signals as input, Bluetooth (USB , micro sd card, FM) only only support stereo (2.0)
I suggest you introduce some protections: general fuse on the alternating network, fuse on each amplifier. antibump circuit and protection for direct current in speaker output. variable gain buffer on each audio input. check the diode bridge if it has a high peak current ... with nearly 40,000 microfarads of smoothing, you can't imagine the initial charge current… it's scary. optimizes charging with a slow charging circuit. the two voltage regulators do not have to work like this, they need two 0.1 microfarad capacitors connected in input and output and an inverted diode between output and input. . between heatsink and power chip, it is better to use thermal paste. the convective motion of the air is wrong on the heat sink. regards.
It's not surround 8.1 but it's mono 8.1 (4ch stereo inside = 8 ch mono, and 1sub ch outside). If u want a 5.1 surround, u need: Front L, Front R, Surround L, Surround R, Center and 1 SUB
This is a stereo setup but with more output, you wont get surrounding effect like 5.1 or dolby, you will get experience like normal amp or headphones, if you use any 5.1 or 7.1 decorder then you can get the real effects

just making 5 1 port surround sound amplifier, not processor. good for using latest computer audio output which is deliver 5.1 audio process, input from gaming motherboard or mini surround sound capable audio decoder. good idea, cost effective. But need to more watts for Sub Woofer out.

Laga sakte ho lekin generally 10% se kam ripple voltage ke liye capacitor ki value decide ki jaati hai. 12 volt ke output ke liye minimum 2000 MFD capacitance per ampere load use kiya jata hai. 10,000mfd ka ek capacitor bahut sahi value hai music system ke liye.
এইটা পিউর ৫,১ সিস্টেম হয় নাই। সাব ওফার লো পাস ফিল্টার সারকিট নাই। এটা থেকে স্টোরি ও সাউণ্ড পাওয়া যাবে। ৫,১ সারাউন্ড সাউন্ড পেতে হলে অডিও ডিকোডার লাগাইতে হবে।
দাদা আমি একটা এম্লিলিপার বানিয়ে ছি ওটাই সাউন্ড সিস্টেম বাড়াতে হবে ও ব্যেস বাড়াতে হবে কি কি পাস পাল্টাতে হবে যদি আপনি একটু প্লিজ বলেন তবে ভালো হয় । 9134901253 এটা আমার ওয়াসব নাম্বার
precisamente eso mismo me preguntaba? en aliexpress venden decodificadores para 5.1 y 7.1. podrian haberse esforzado y colocarle uno y si pensaban hacer un amplificador multicanal pudieron haberle conectado un control de tonos

Sir I have a doubt that i have a resistor but i do no its value pls tell me the value its colour code is (red, black, black, black, brown) pls sir tell me the value
what you make is a amp with 2 ch input and 2 x 4ch output not an 8 ch amplifier. And also that is not surround Amp because you dont use sound processor, for 5.1 at least you must use sound processor like Dolby Digital system or better
if you use independent signal input for each amplifier you can make suround system, but you will need suround input signal. For 5.1 you can use 1x 2.1 amp, 1x stereo amp and 1x mono amp ( center channel).

Long ago I made 4 channel surround sound with one 4440 plate n two 6283 plates it was good as heat sink was big n two transformers of 4 amp each 12 0 12 ...
Make it with 4 bord or 4 different bords....and put a passive crossover which are inbuild....one bord for sub, one bord for Mid, one bord for Woofer, one ford for tweeter, And do bord design same size and different types like 30w, 50w,100w,150w,200w etc and then do the magic ... Change the perticular bord if need more power or just simply pick bords of customers choice like 100w sub and 200w mid and 50w tweeter....at same power supply Power supply 12v 4amp...and put power enhancer with protection in each bord or customer change power supply if he/she need 2 bord or 3 bord as per as required.
Just be creative. 6 channel amp. 4 channel satellite with full range speaker. 1 channel for voice with LC filter that cut off 8~20khz and 20~100hz for voice. And 1 of the channel is for bass. Filtering out 100hz ~20khz frequency. Not enough oomph? Find yourself mono channel high watt amplifier. Add proper LC filter too. 6/5.1 Channel is not enough and you want 7.1/8 channel surround? Add another 2 channel amp kit for satellite surround.

I think it is not surround amplifier,, but amplifier 4 chanel
Only 2 chanel
Is not 4 its 8 channels no way
Stupid it's 4 amps with a channels.... Go harvest and shut up
