FBHDZVV Audio Amplifier TPA3116D2 Dual Channel Digital Power Board XH-M543, DC12-26V 2x120W DIY Module High Power Stereo Amp Board for Car Vehicle Computer Speaker DIY Home Theater Audio System

These are excellent little amps. You can add a blue tooth module and amplify about anything. I used one on my old flat screen TV to improve the sound. They are small and an old laptop power supply works great to power them.

This little guy packs a punch for it's size and cost. It has nice sound quality too, I got it without a real purpose in mind. I was installing a system in my car and wanted some options if one component was lacking power, didn't need it. Ended up using it to rig a Bluetooth amp for my guitar. I used it as s preamp from the guitar to the bt transmitter, this is a very weak signal, and a lot of amps wouldn't have recognized the signal, it sounded great, like tube amp great (I'm no expert, but the first remark anyone makes when they hear it it "oh my god, it sounds really good"). I also put it on a set of 12" 3000W Kicker L7s, now I'm not saying it did the job, but it pushed'em, loud enough to have been a home theater subwoofer in a medium sized room, I was just playing so I didn't even have a low pass filter set up, so it was amplifying the full spectrum and getting 90% of that filtered by the subwoofer protective filter and still it wss impressive considering 1800W minimum is the manufacturers suggestion for them. Only con for me, no power button, but I just wired a toggle switch on the dc voltage line and am happy with my $12 amp.

It meets its power specs. I like that it includes a shielded analog signal input cable. It has input signal attenuators for both channels but the gain of the amp itself is fixed and quite high. It would have had a better signal-to-noise ratio if the gain of the amp itself was lower.

I love this amp, it work amazing if you have a good power supply , the sound quality and the efficiency is incredible for the price.

This product is a straight up lie. They glued the heatsink to the chip using thermal paste so most people wouldn't mess with it, but I removed the heatsink and found that this is absolutely NOT an authentic Texas Instrument TPA3116 amplifier chip. Instead they are using a cheap (and terribly rated) Chipstar CS8673E. Although the power output wattage are similar, the Texas Instrument TPA3116 chip that they tell you is on this board can output its rated wattage with 0.1% THD (How much of the sound gets distorted). At 1% THD the sound quality starts getting noticably bad and something you'd pretty quickly notice so the TDA3116 at 0.1% THD is pretty good.HOWEVER, the knock off chip they are actually using (Chipstar CS8673E) has a THD rating of 10%!!!!!!!!!!!!! It's outrageous! This means that as you turn the volume up and start pushing the amp, the sound quality will be horrible with intense distortion and garbled sound. Basically the manufacturer is vastly overrating this chip, probably intended to be a cheap knock off alternative to the proper TI TDA3116. However, it's functionality useless at that THD rating and likely puts out only a small fraction of the power of the actual TDA3116 at an equivalent 0.1% THD.Long story short, this product is a knock off, they are lying about the chip, it does not output anywhere near what they claim, and the sound quality will be complete garbage.

This little amp has power! Running one channel to a BOSE acoustimass 10 subwoofer and the other side to a full range center channel speaker for “mobile home theatre” Nice having the 2 potentiometers. Running it off a 20volt power tool battery with no issues. Glad I took a chance on this little amp!

Good....

I like this amp, I'm running two of them right now for my home system. One for mids and highs, and one for the sub woofers. I use a bass controller card on the base one for sort of a crossover. I have 12's and I'm running 19v with like 8-9 amp old laptop power supply, so plenty of power, but i think they're too big. Would get like 8"or 10" maybe. Maybe even just a pair of 6"s in a custom box. I've seen those 12s work a lot harder than this 220w wannabe pushes them.But on the mids and highs i got some 6.5" 3 ways, they sound pretty good. There is a tiny hiss of you turn them all the way up, i just notched em down a bit from full. They don't make a lotta heart and they got a good heat sink that is glued on, i guess (no screw). I wanted to redo the thermal paste but, on well. I like mouth of them though. One I've been running a couple months now, the other I just got last week...
