I was very frustrated and thought of buying a new and different amplifier.

Wise ghar me Inverter bhi hai aur 12V battery se bhi line nikaal satka hun clean 12V ke liye lekin Inverter Battery dusri taraf bahut door par hai aur kafi lamba wire lagaana parega to SMPS se kaam chalata hun. Now it does not heat even if I keep it running for 24 hours continuously. I have used it now for more than a month and it is running without any problem. I use two 4 inch Speakers left and two right. In addition I also run a 6 inch Sub Boofer (I had one of Panasonic system which main system is not working but Sub Boofer still in working Condition).

Bhai yaha IC ke internal noise ki baat ho rahi hai. Abhi class AB aur class D ka jamana hai. Class B ic kahi use nahi hoti ,india aur developing countries ke alawa.
Aap ne ek dusre video mein kaha ki La4440 ki double Ic amplifier board mein 12 V , 5 Ampere transformer lagana chaiye, par branded company jaise Sound king apne 4440 amplifier mein 12 v, 3 Ampere transformer hi use karti hai jisse amplifier board aur Bluetooth module dono hi power lete hai. Fir aisa kaise possible hai? 2) Second question yeh ki aap ne kaha tha ki transformer ki efficiency 90% tak hai, toh fir log kehte hai ki smps ki efficiency bhi 90% hai. Aisa kaise? Jab ki transformer me losses jada hai?

12 V DC pe IC nahi jalta hai. Agar ghar me inverter hai to inverter battery se 12V line nikala ja sakta hai. Ac power se chalane pe IC bahut garam hokar jal jaata hai.
Stereo mode me 6 watt per channel. Bridge mode me 19 watt total. Lekin half power pe hi noise level control me rahta hai. Full output pe 10 % distortion aa jata hai
Sir mene do 4440 plate use kiya hai dono me ek hi Bluetooth module SE input Dena Chahta Hu but sound Nahi mil Raha hai dono plate me separately deta Hu to output sound milta hai .! Lekin jab dono me sath input wire connect krta Hu to dono SE hi output Nahi milta.....!!!
LA4440 IC to Ghoda hai. Abhi tak Chinese copy CD4440 mil rahi hai, demand 43 years se jo doud rahi hai, ghoda nahin to aur kya hai. Other parameters ko peeche chhod dijye. Kyonki heatsink parameters koi bhi pura nahinn karte hain. Metal body main 500 gram heatsink runway mil jata hai. Isiliye yeh ic tagda chala. LA4508 bhi stereo tape audio je liye theek tha apne waqt main. Lekin availablity nahin hai India main. China main abhi tak mil rahi hai. AB amplifier main TDA7297, TEA2025 ya uska pin to pin equivalent jaise koi amplifier board ka dikhana.
1230 is better than 4440 but again it is class B which is not good. Please go for LM3886 if you can afford. It is even used in studio monitors. Otherwise TDA7294 is best for performance and value for money.
1 thingh is 4440 ic is not worst beacuse today their are many copy conpmanyes are making 4440 ic so that we thought that it is worst but in 10 years ago the 4440 ic is made in japan and japan made original ic and today there is no original ic are made
