TPA3116D2 50Wx2+100W 2.1 Channel Digital Subwoofer Amplifier Board 12V-24V Power TPA3116 Xh-M139 Digital Amplifier Board

I used this product with Bluetooth module & high bass Sub-woofer. Bluetooth module was connected by different Power supply to stop humming noise from this amplifier, and on this amplifier I have used 12 V 5Amp Smps. This amplifier works more better than my JBL Sound Bar and the main point is that you can control the Bass, high/mid frequency stereo speakers and total volume individually with the seperate volume controllers.

Review From an auiophile. You get the same on aliexpress at a cheaper rate and reason why i got it here is delivery time, amazon shipped next day. The amp out of the box is well built and performs well. I used a 24v 6A power supply for giving it the best power output. Make sure you are connecting your speakers in series or parallel based on the ohm rating on ur speakers 4 to 8 is what the amp can handle. The highs and mid is absolutely fantastic. The bass however is good and punchy but you can hear content on the bass till like 4000hz, use a filter seperately to cut off the mid highs. I ran at 90% vol for like 3 hrs straight and no issues.

I using last 7 years is bass sound like jbl 500 pro ,,, need use proper voltage,, u feel good sound this boad , I get 1300rs

Good quality no doubt

I received this item in a poorly packaged box . And once i powered it and hooked to speakers it was working. After some time the knobs stopped responding audio became channeled and by the end of the day it stopped . All i was getting the blue power light and nothing else . I filled a return which got accepted and money got credited back Maybe the product was defective or something might have happened during the shipping The power supply and speaker load was well under specs so i din't overload it anyhow... So put some extra money and buy a better one

Stereo speakers worked well; but Sub Woofer Bass Poor. Full money refunded. My logic is value for money; not for JUNK!

Its the best thing for your homemade speaker project Its just not capable for me cause for some reason when i play music at full volume,the sound quality is not good,but still if I click my phone's volume down button the sound quality is good I'll totally recommend this, just a bit expensive...

One day work after one off the speaker stopped..its like voice was on off on off... Maybe one ic damage..

Just ordered it because it was so small with big numbers for output. Hooked it to a 12v 5a computer adapter and a 10 inch sealed sub and a couple of studio monitors. Cranked the two right knobs and adjusted the left for the monitors. Plugged in a Logitech Bluetooth adapter and selected Abbey Road to check the bass. Wow = clean punch and clear as the Pink Floyds Dark Side of the moon. Held the board close to the equipment but did not notice any hum. Like the full ground shield as the bottom layer of the board. Runs cool even after an hour of listening.

This is a review for the 2x50w + 100w board. It is excellent, especially for its small size. Almost no noise when nothing is playing. The knobs are all volume knobs. One for the left and right volume, one for the bass volume, and one for overall volume. This allows you to adjust the relative volume of your sub and satellite speakers to correct for different efficiency levels. My only complaint is that it does not reject RF noise very well. I tested this with two Bluetooth boards. Both boards worked fine with another amp, but with this amp one of the Bluetooth boards generated a lot of RF noise and the amp did not reject it. The amp picked up the RF noise even when the BT module was not connected to the inputs. So, it was purely RF noise and not on the signal lines. The other BT board did not generate any RF noise and sounds amazing. My testing was done with 5s lithium ion batteries for the amp at about 18v and an isolated 12v power supply for the BT boards.

I haven't checked the actual output of the board but I would be willing to bet it is putting out more than advertised. I have only 2 complaints. First complaint is the fact you can't control how much bass is going to the full range speakers. You can the volume but not the bass or treble. A good crossover might be recommended. Second complaint; the heat sink is mounted by a single screw. After I pushed the board pretty hard for a few minutes, the heat sink became loose. I had to remove it. Clean and reapply joint compound before reinstalling the heat sink. I also applied a small amount of epoxy to one end of the heat sink after I had reinstalled it to make certain it couldn't move in the future.

Background I have an Altec Lansing InMotion im7 ipod speaker whose built-in amplifier started to flake out (a known issue with that model). I have always liked the sound of the speakers enough that I didn't want to just recycle the unit as e-waste. After I opened up my speaker unit, I found that it had stereo drivers with a separate subwoofer, so I knew I needed a 2.1 board that could power a passive sub. So I found this Yeeco board. I already have a Yeeco knob-style amplifier and have been happy with it so I gave this one a spin. The board is way smaller than my original Altec Lansing board (also a class D amplifier), but this a $30 board, so expectations should be managed accordingly. Getting the amp to work my old was pretty much a snap, and it sounds good. For power, I just used the 17V AC adapter for my speaker without issue. The biggest drawback is a faint hiss when there's no signal present, but you have to really listen for it. If you're picky, it'll be a dealbreaker. For me, it was a minor thing, as you can't hear it when it's playing music. In terms of whether you should buy this -- if you don't need to drive a passive subwoofer, you should get a simple 2.0 stereo amplifier board instead. The sub out is NOT a simple line out to a powered sub, and that could be problematic if you're trying to do that. If a 2.1 amplifier is what you really need though, this board is a great buy for the price. The Good Parts * Controls for stereo gain (it is not a balance knob), bass gain and master volume * Standard 12V barrel connector * Has an alternate power connector and a three pin alternate audio input if you want to wire your own switch into a custom case * Screw terminals work well * Sound is pretty good * Can get pretty loud (ymmv, depends on your speakers) * On board LED to indicate that power is on * 50W to the left and right channels, 100W to the passive sub channel * Easy to set up Could Be Better * Faint hiss when no signal, but most people won't notice * Design of the board might be difficult to retrofit into an existing speaker chassis * Popping sound on power on, regardless of what the master volume is set to * No power switch (turns on once power is plugged in) - you can add your own by using the alternate power terminal * AC adapter not included * Knobs are cheap looking, but expected for the price * No alternate pin connector for the LED * Might be hard to find a pre-made case for it (is a non-issue if you're not looking to put it in a case) * If you can't change equalization settings on your music sources, your mileage may vary in terms of whether you can fine tune the sound to your tastes

Small footprint for hidden system (I put mine on top of the cabinets in the kitchen), wet surprisingly powerful and sound clarity is quite good considering the price point. Don't expect anything remotely close to audiophile sound reproduction, but hooked to gold speakers from a dead stereo, you can salvage yourself a great sound system for dead cheap! It is power hungry though so don't skim on the power supply!
