Hosyond Bluetooth 5.0 50W+50W+100W 2.1 Channel Subwoofer Amplifier Board TPA3116D2 HiFi Treble And Bass Control Stereo Digital Audio Amp Board For Home Theater DIY Wireless Speakers

This is one of the best 2.1 channel amp. I had oneplus q2 pro 65 inch tv and the tv stopped working after a year but the tv had best sound system ever,i never saw a tv with such sound system. So basically i wanted to reuse that sound system with my new lg c4 so i took out the speakers subwoofer and the tweeters from oneplus tv but the sound system was passive and needed an external amp to drive them. I ordered couple of amps before but they were giving good sound quality. Finally i ordered this amp with seperate channel for subwoofer and it works amazing. For now I’m using it via Bluetooth and the sound quality + bass levels from subwoofer are 8.5/10. I imagine how good the quality will be via wired connection,so i have ordered DAC,digital optical audio cable,aux and i know it will sound much better via wired connection. I have checked all the 2.1 amps on amazon some good brands are above 8k and the ones under 8k aren’t good. Don’t judge this amp considering its cheap price,just buy right away. Only thing i am concerned about is its logetivity since it has no warranty. Rest i can assure you that its the best amp.

Good Product Best Sound Quality

Good sound quality

Superb…highly recommended

I bought this on an impulse when I found an unused passive sub, so that I could get better desktop sound. There are no instructions/manual/documentation but fortunately this product is globally popular so there was enough help going around. It was an easy setup, and when i first played it, I nearly fell off my chair - my cheap setup sounded like something 4-5 times this price. I am using the amp with 2 basic Micca bookshelf speakers and a Tribit passive sub from a cheap soundbar. If you shut your eyes, the setup has the sound of much bigger and far more 'evolved' speakers. I paired it a decent power supply that I had bought for an old Topping class D amp. The bluetooth works well and pairs fast - a little too fast sometimes since it aggressively connects with previously connected devices as soon as they are in range. The sub crossover is a little difficult to get right since there are no frequency markings. A curious thing that I found on the amp board is that it has expansion ports for mics (I think) and for some other functionality. There is no mention of this online. I would have bought this much earlier if it hasn't looked so ugly :) but after hearing it perform, you can forgive that easily at this price. So good!

Supar quality hai kam voltage me bhi bahut chachha chalata hai

Nice bass

Quality is good but The 2.1 amplifier arrived without the screws and pillers ​Could you please assist me in obtaining the missing parts?

Ficou mais barato montar o som.

Works is great for my simple PC audio setup. No noise or anything via AUX or Bluetooth.

I bought this for some leftover car speakers I had laying around. I can't really comment on whether it provides the advertised power, but I can say it works. I've powered it with a 24V/6A power supply via barrel jack and the 2-pin from a Ryobi 18v adapter, no issues with either. Left, Right and Sub channels all worked fine, no issues there. Connecting was simple, you turn it on and it's automatically broadcasting, connecting had no issues. But for whatever reason when using Spotify, the first few seconds of a song would just be skipped whenever the song would change. Nothing too huge, but it is still something to bring up. Some other issues were that I feel the sub control knobs were switched, where frequency was volume and volume was frequency. Again nothing crazy since I only had to adjust once, but still something. I also wish it could power itself off like the mono amp ZK-1001U instead of going into standby. I had some power switches laying around to get around that though. Overall, not bad, this was my first time buying an amp board like this so I might look around at others first, but I wouldn't feel bad if I had to buy this again.

Surprisingly clean output and with 24V/8A power supply it has enough headroom to drive inwall L/R/SUB system.

I'm not going to lie, I thought this was going to absolutely horrible but I was blown away. I ended up 3D printing a case for this if that helps to express how impressed I was. Granted, this feels cheap. The nobs are meh, the DC port sparks when you plug it in, and the wires are completely exposed, but dang it sounds nice! Its crazy. The sound fills every corner of my apartment. My wife was even impressed with this odd effect, she'd walk into various rooms and come out saying "the audio hardly changed wtf!?" I guess she likes it. I replaced the stock speakers in my car and used this to recycle the old car speakers into a makeshift boombox out of cardboard. I actually started laughing at how good the audio was for this type of setup, I still laugh about it when I turn it on. I sits on my workbench and my friends see it and instantly have questions. I turn it on and we all have a laugh, its fun really.
