  9. A***n

    Great amplifier. Delivery zipper. The sound is gorgeous. Connected from the laptop power supply.

  10. D***v

    Excellent sound, but of course the power of the device is overstated. Fast delivery three weeks. Thanks to the seller, I recommend!

  11. K***s

    pagaidām viss ir ok

  12. D***k

    It came for 2 weeks, it works very well. I’m pleased.

  13. S***e

    Arrived very fast, well packed, product great… met expectations…

  14. V***h

    The sound is clear. Fed from 12 v 1.5am plays clearly on 20 watts of columns. But the power needs more than that, I’m waiting for the block to arrive. I’m happy with everything. Take it will not regret it. For the house is enough, everyone will dance. Frequency adjustment works well, but high on all seems to start pounding, not playing, but rather these are such columns.

  15. J***s

    140w speakers and 300w sub, sound very good. Small power adapters wont work, using laptops adapter.

  16. V***o

    12d delivery. Packing is good.

  17. V***v

    Installed TPA 3126, can work on a load of 2 ohms. Heat sink, by date from 70 cm2 per chip, if you DJ and voice rural discos. The seller and I recommend it. I recommend the seller and the product.

  18. S***v

    Packed perfectly, a box in a box, padded with foam. At first glance, excellent, we will test.

  19. A***v

    Excellent performance, everything works.

  20. P***a

    Good sound, treble, bass and freq knobs are working nicely. No pop sound when powering up, but quite big pop sound when loosing power. Nice short melody after power up (no chinese sound or chinese woman). Only problem was unbelievable huge tighten force on heatsink bolt. That worker which did that was really stupid. Circuit board was totally bended and almost cracked. Because of that whole force was made on chips edges and heat conductive paste had no contact. I dont understand how could chips survive this. Furtunately after paste replacement and gently secured heatsink, everything is working properly.

  21. J***j

  22. K***v

    Complete set, thank you to the seller!
    I’ll add how I check…

  23. N***v

    Then they stopped.

  32. A***a

    Fast delivery. Surprisingly good assembly quality! Includes screwdriver for DIY mounting. The sound quality and tone control options are also surprisingly good for this price. I’m happy listening to music from mobile gadgets via Bluetooth
    I recommend!

  33. I***v

    Blutus for some reason was not at first. And fire. For those who want sound more than from the usual car radio. Plays from 24 watts. Because From 12 W begins to play porridge above half the volume

  34. AliExpress Shopper

    looks great additional feedback after testing

  35. N***f

  37. a***s

    Boa noite, chegou em perfeito estado gostei muito do produto!bem embalando.recomendo o vendedor.

  38. A***.

    Хороший усилитель, но то что два выхода на 50 ват, а один на 100 ват – в этом я пока не проверял, но преобразовывает звучание довольно та ки солидно – почти на простых динамиках. Товар был хорошо упакован – на фотографиях видно. Спасибо за запасной болтик – очень пригодится, если какой то потеряется. Все части легко собираются в общую конструкцию. Нравится и компактная-маленькая конструкция самого изделия

  39. R***s

    получил спасибо.

  54. K***o

  55. v***v

    A little flux I’m trying to wash alcohol, the settings handles are spinning well, it’s very screaming it’s aesthetic, it’s necessary to update the paste under the radiator and, this second is The entire frame of the amplifier this iron heat outage will be 200%, grettering will be only 24V, xyp40w with 2 x 40w paged 250 + 250 + 180 + 180 + 200W home theater speakers in parallel connection I doubt that I have enough power.

  56. a***s

  57. M***k

    amazing amplifier for the price, BT is working without problem, good sound, easy to install.

  58. M***v

    Excellent amplifier, very stylish design, the sound is perfectly cut over the frequencies, the power is grasped to tear the speakers. Produces a quiet sound when working, almost not noticeable.

  59. AliExpress Shopper

    Produto fidedigno com o anúncio. Bem embalado e chegou no prazo, fácil montagem e conexão com bluetooth . Já fiz testes, e o som é de boa qualidade, impressionante! Usei fonte de notebook que não usava mais e funcionou bem (veja a imagem)

  60. E***z

    Professional SELLER.
    I ordered two type of amplfiers. One had quality issue, the second item, two pireces of amplifiers sent back without delivery (by post) to .
    The seller realised it, communicated to me by messages the delivery problem, accepted my quality claime and sent again the 3 amplifiers properly.

    THANKS a LOT.

  61. AliExpress Shopper

    The build quality is excellent. The bottom of the board was a little bit of flux residue.
    The food was supplied from the laptop BP 19 v 3.42 A. Speakers from the Music Center of Sony. SAB from slabenkogo 5.1 Samsung.
    Sound at altitude. Very deep frequency adjustment. Excellent adjustment of the volume of the sub. Unless-when you raise the HF at maximum-you can hear the sound of synchronization Bluetooth, but not critical.
    Plays quite qualitatively. In the connection above-he played 3-4 songs-the radiator is slightly warm.
    Recommended for purchase!

  62. D***v

    82 дня до Казахстана. Качество норм. маловато басов в колонках и перебор средних, без саба звук не радует. С сабом более-менее. Получше музыкального центра средней цены. при воспроизведении от бт на малой громкости, если прислушатся, чуть слышно шипение, т.н. звук сала на сковороде, на ауксе такого эффекта нету. С подключением бт проблем нет. Сращу поменял термопасту. Запитал от бп от ноута 19в 4.74 а. При средней нагрузке около 50-55 процентов регулятора и подключенном 2.1 4 ома- потребляет примерно 1-1.2 а, не греется. При малой нагрузке – процентов 10-15 от положения регулятора громкости – около 0.1 а

  63. A***k

    Доставка быстрая, упаковка хорошая. Комплект полный. Всё работает, все как в описании. Качество хорошее, звук чистый. Входы/выходы рабочие, блютуз в наличии. Все отлично, рекомендую!

  64. T***a

  65. T***a

    Simply fantastic
    The sound is very clean and without noise

  66. B***s

    Pequeno poderoso! Usando com 12v 10a é suficiente pra empurrar qualquer caixa de 100w + sub 200w

  67. E***e

    Well packed, fast shipping and the product fits the description. Good purchase.
    I recommend this seller.
    There’s no proof if it works.

  68. J***s

    I’m impressed I printed a 3D enclosure for it. Paired it up with 2 140w speakers and a sub and wow!

  69. D***n

    Fast delivery, beautiful sound, clean, no foreign noise, for this price-it’s a find, it works from the laptop BP 19 V 4A

  70. Ö***n

    I had previously owned tda7293 with the red pcb it has broke down. I have tested this amp and it’s awesome. I have ordered speakers for it. I turned down the plates im a minimalist

  71. AliExpress Shopper

  73. AliExpress Shopper

  74. A***n

    Decent amp at this pricepoint, works quite well on 12v will try 24v soon

  75. v***c

    Super effort. I liked it. From 12 volt, 4 amp power supply, it works loud enough,. Does not heat at all. I think that with a higher voltage will work well.

  76. g***a

    producto testado mas de mes com fonte 12v no esquenta boa potença no fui taxado

  77. S***b

    Огонь,запилил к усилку две колонки на 20-х и 13-х динамиках,на канал сабвуфера кинул буфак на 100w из тачки-долбит так что посуда дрожит, доволен как удав ✌️.

  78. A***v

    Everything works. Packed well. The sound quality is quite decent. I liked that when you connect the Bluetooth, it simply produces an unobtrusive sound signal to uselk, and not an irritably hanging aunt or man.

  79. M***o

    Object beautiful all ok thank you

  80. M***i

    Plugged in. Toli to pick, then-whether I argue. Bluetooth connects, the diode lights up-there is no sound. Riddle.

  81. A***n

    The amplifier for its money is excellent and quite cute ….

    I’m happy with the purchase, I took the version more expensive, everything works. In Bluetooth mode, delay sound from video half a second, but it’s not critical for me

  84. E***a

    Ordered in the evening, on the next day sent, the packing is good.
    Connected the amplifier to small columns and Sabu from the house. Cinema, quite a good sound, when connecting Bluetooth Baba does not scream, in general, satisfied.

  85. E***v

    A very good amplifier, its money is worth, there is only one nuance, when you play games on the phone and in the game there is almost total silence, why then the sound the sound

  86. F***a

    Met expectations. For use on television is need buy a adapter, coz the televisions newest has auxiliary output.

  87. V***v
