FBHDZVV TPA3116D2 Amplifier Board, 50WX2+100W 2.1 Channel Digital Power Audio Amplifier Board Subwoofer Speaker Stereo AMP Module Adjustment DC 12-24V

I powered this with a 19V power supply from an old laptop. I attached speakers and a subwoofer from an old TV audio receiver and it works great. Given that I used 6 ohm speakers and 19V power, the theoretical maximum power would be 60 watts. I'm able to get nice clean noise-free audio at that power level. The separate volume controls for speakers and subwoofer allowed me to get a good transition from bass to treble. A minor complaint is that there is a loud pop when the unit is powered up or down.

I did not check the power output of the stereo (highs/treble) side, but I did test the subwoofer/bass side of this and all I could get out of it was 26watts. So 1/4 of what it says, so I'd assume the same for the stereo/highs/treble side of the amp, so that is probably around 15x2. 18-20VDC seems to be the sweet spot for power. Any higher and this amp gets very hot (233F w/24VDC).The bass side of the amp is weak. You turn bass knob up, treble down, and the highs will still over power the bass. Maybe need to use a lower power subwoofer. I tested with a 12" 4ohm 100watt rms sub (it is good quality, just not enough power) also tested with 8" 8ohm, 6.5" 6ohm, 5" DVC 4ohm each coil, and a tiny 4" subwoofer part of a samsung bluetooth bar. The 12" sounded the best. I did also test with another 12" 4ohm 400watt rms and I barely heard it.Also note the knobs are not a frequency control, all 3 are volumes, treble volume, bass volume, and overall volume.Overall this is pretty good amp, just needs a little more power on the subwoofer side.

The item matches the description perfectly. It is built to be heavy-duty, ensuring durability and strength, making it ideal for demanding tasks. Additionally, the price is quite reasonable considering the quality and performance it offers. I wholeheartedly recommend this product to anyone in search of a reliable and sturdy option.

The media could not be loaded. Like the durability of it, I haven't exactly done much to protect the board itself and it has held up. Sound is pretty good, no noise at all actually. I've been running decent 5.25" 2-way DS18 x2 and a 200W 5" mid-bass sub from it with no complaints. Now running 2x 6.5" and the same sub, sounds even better so the output watts are there. Sons project McLaren... pics aren't most recent. The car now has 2x 6.5", 2x 5.25", 2x 3.5", 2x 1" tweeters, 5" subwoofer and rocks.

Had a busy year. I finally got around to do my project. After hooking this all up turning on power. The only sound was from the subwoofer! I mean that part worked amazingly. I needed it to work left right and the sub.

Actually it's closer to 25 +25 + 50 watts, good sounds quality but short in power

It says 100 watts, and it's true. I actually was able to pull 150 watts through the bass channel and 100 watts from the left and right so you get more than what is advertised. The independent channel controls are nice too, If you are facing towards the face of the knobs the farthest left knob is the Left and Right channel volume, the middle knob is the Bass channel volume, and the farthest right knob is the Master volume. As for the terminals, if you are looking at the amp top down with the knobs facing towards your chest, the farthest left terminal is the left channel, the middle terminal is the right channel, and the farthest right terminal is the bass channel. The screw in wires are great, and the aux input is a life saver, it is a hundred times better than the 3 pin input, those things drive me wild. I'm running mine on a 7.5v power supply. It says you can use 12 volts, and yes, you can, but you have to be much more careful about the amperage of the power supply if you use 12 volts, as it will get hotter faster. So you could buy a lepai amp for 40 dollars and get 25 watts on 2 channels, or you could spend 1/4 the price and get 4x the power. Get this amp.

I've been using the little two channel Xh a232 two channel amplifier board that's 30 Watts by 30 Watts and it would blow this thing out of the water this is nothing I only got it as a preamplifier for a big powered floor subwoofer but I'm not sure it's going to have enough output signal to make the Taramps 250watt 2 channel amp bridged to mono at 4ohms really produce any bass and I will guarantee this if it doesn't I will be returning it because the xha-232 at 12 volts produces way more power than this and I just tried it with a 15 volt power supply and no change it's weak very weak
