Hi!
I apologize in advance for bad English. I need a power amplifier chip with a single supply.
Power battery 12v 7a/h
Technical specifications speaker
POWER HANDLING (RMS/MAX.) 100 / 180 watts
IMPEDANCE 4-8ohms
SENSITIVITY (2.8V/1M) 91 dB
FREQUENCY RESPONSE 32 - 32000Hz
I am considering tda8560. But perhaps there is something better? Interested in sound quality. Thank you!

TDA8560 is very good and I guess easy to find everywhere.
ALL chipamps are way better, flatter, cleaner than the speakers they are driving, so no need to agonize comparing minuscule datasheet differences.
By ear, "they are all the same".
Use the one you can get locally.

Perhaps, at a load of 4 ohms, the chip TDA7850 will be more powerful than the chip TDA8560? With distortion up to 10%
After all, the chip TDA8560 is designed for a load of 2 ohms.

TDA1562 how is it relative to TA8210AH, TDA8560 and TDA7850 in terms of sound quality? She has a lot of power and it's hard to get clipping.
Tda1562 was a Class-H audio amplifier specifically made for car audio & is now obsolete item. Try something new. For battery i strongly recommend class-d amplifiers.
Which one for the battery? I bought a ready-made amplifier at TPA3116. It makes noise when there is no signal. And gets high distortion very quickly.
TDA 7377 An Oldy but still a good one... 12 V single supply. It was intended for Car audio and.. Widely used., in a lot of Premium head units. as quad speakers or 2.1 (sub) setups
Sound is surprisingly Good. Wayyyy better sounds than the 3116 /8s things (from experience) 🙂
Buy a cheap a** Chinee Kit ~12$ and substitute decent quality parts Caps, Op amp etc and you will be surprised..

But I bought TDA7560 today. They seemed to be in stock in our store. If I only need two channels, can I just leave the other two free?

In principle leave unused outputs open, "connected to nothing", and inputs grounded.
In general given your humble 12V 7AH power source, use "Car Radio" type amps which expect that, not "regular Hi Fi" types such as TPA**** , etc.which expect higher voltages.
And be realistic, you can get not more than 15-16W into 4 ohm out of such low supply voltage.

I am currently using a Chinese amplifier on tpa3116. The battery lasts about one month without charging. And this is good. But the sound quality is poor. That is why on the new system I want to do it differently. And get better sound.
Im afraid that the converter will introduce noise
make sure it is not just because of low voltage (distortion rises quickly at relative low levels).
otherwise you will have the same problem with other amps.
you could try your tpa3116 with a higher voltage lab supply and check the sound quality.
I'm not talking about distortion. I'm talking about the fact that the sound from the tra is some kind of metal. I don't know how else to call it.
Most car amplifiers use boost converters and they aren't generally noisy...
