I received the amplifier quickly, it was packed perfectly, it came with other parcels, but the total package was opened for some reason, and so everything is intact! Now about the amplifier itself.Before turning on checked the availability of thermal grease, it was not, but anyway, dabbed Kpt-8 and everything ok.Connected from 12v to the speakers from the center, played great, I liked it, neighbors too! I have the same, only on tpa3116d, it was not enough for s90b, but the sound is great.I hope that this will be great and he still rocks them as it should.But preverify there is no way, the speakers at the cottage, just order a PSU for 30c. And by the way,I think it will be necessary to unsolder the resins, which are in parallel at the output, because the speakers are 8 ohms, and they stand, that would be possible to connect acoustics less ohm at the same power. In this bunch sound rated even my brother, who does not take class D at all!

It really works!!! Under the radiator is dry! First thing I did was apply thermal paste! I hooked it up to a C-90 steamer, it works and pumps normally, I had a 20V 4.5A power supply.

Only regret that it with the Chinese voice begins to work better 24 V than 12 V

The board is great. Arrived quickly, product is serviced. It works properly, plays loud. Sure it's a little flimsy, but for my money it's great. I recommend it!

Works great, only there was no thermal paste under the radiator (good thing I saw the comments and checked). The S90 speakers will pull easily. The power supply 12v, 1a is enough to listen pretty loud. Bluetooth always works and turns off only when you connect the AUX cord, the flash drive has not checked.

Recebi o produto bem embalado, funcionando perfeito. Só precisa colocar pasta térmica no chip, dissipador sem nada. Tocou uma.corneta automotiva tranquilamente, vou testar com um sub melhor, o que eu tenho está distorcendo, mas creio que seja oa falantes pequenos. Bluetooth fala em chinês, mas tá de boa. Tomara que não esteja praguejando kk.

The build quality is good. Came in a box, in a dielectric bag. Tested it on a 5 watt speaker, rocked out to full power. The device worked from an old 19v 4.7A laptop power supply. It is nice that at the input is a diode. When I switched on the speaker, an unknown girl in Chinese started babbling.

Delivery 10 days, picked up at the five. I am not a specialist and not a musician, as for me done very well, and what you expect for the money. all works, only micro sd not checked. bought in a garage, because remained from the center lgi speakers 50 watts. connected to the PS from a PC. I think just not enough voltage. advised all 24V. to try another charger from a laptop. in general, advise. by the way, heatpaste also was not, as well as many. applied, to test 15 minutes, the radiator is cold.
