BigDWiz great video! I Love watching these tests videos, I got a home audio amplifier by Adcom it's the gfa 5300 mosfet, it would be great if you could test this one?
BigDWiz like the other guy said... Chinesium amps... Please order them from wish or geek... Been wondering about those for my old crappy toyota with 0 security whatsoever... Looking for crap no one wants to steal... But does the job.
I can't believe you have a Dyno test for this amp! I literally just found amp on Amazon and decided to look it up on RUclips. I can't thank you enough for this video man lol thanks
Imagine if they had these back in the day (90s). I'd have bought one and put it in my boom box so I could have the loudest boom box on the block lol. Im sure I'd burn thru alot of D batteries though 😆
got this thing together with a splitted one for my ~ 200W 2.1 system. did build it with some high end high and mid range speakers and a 150W RMS Kevlar Subwoofer ... at just 1/5 of bass my neighbors going berserk on me. system in total cost me around 120$ (100$ for speakers, 20$ for the 2.1 amp). and BTW I got some high end system from Logitech and Bose, both around 200-300$ but my self made system is still my favorite one. only minus is that its slightly hissing when no audio is plugged in. but that's the only thing
Did some tests on a TPA3116D2 sub amp. 2 ohm non inductive load 24 volts supply they will do just 100 watts at around 1% THD. Problem is the inductors on most of these Chinese amps just aren't up to the task well among other things. The TPA3116D2 chip itself can do the business if you can find a decent board. The way the batteries in this test were wired together would have caused a voltage drop, I mean stuffing wires in holes is not really a good connection.
I would like to see more of these tests with these Class D amp lot of people are using them out there for projects and such it be nice to know what they actually do
I agree, perfect little amps for home made boomboxes or even for retrofitting into old boomboxes. Again, main issue is 24 volts, but you could get by with 12 volts if you don't need as much power. Pretty cool they can handle such a wide range of input voltages
I have built several small projects with them. I have 1 running a small system with cigar box speakers and a 5in sub. It's a 2.1. I have some sitting around tell me how to send some to you and you can test a few more.
Thats bad ass. I like this because it is different unlike a car audio amp test. Nice job you should test more of these little eBay amps because these seem to be big sellers for little audio projects with the Bluetooth boards.
Another great video! Thank you for testing such a wide variety of amplifiers. The ratings on these amps are based on the heat they dissipate -- not the power they produce. If you can squeeze 50% of the rated power out of these then you have a quality amp.
It sure appears that way by the specs of the chips, but the sellers are advertising them in a way that would make the consumer think these are the actual wattage output. Either way, now we know the truth
If you read the TPA3116 spec sheet. it is rated at 50wpch at 4 ohms at TEN PERCENT DISTORTION! so bridged mono it is rated at 100watts at 2 ohms..again at 10% distortion!
I just bought this open box on amazon to run a cheepo sony subwoofer from a blown receiver to add to my Z-5500. I just subbed because I randomly came accross this DYNO!. AMEN! Kudos, keep it up!
I was given a JBL Sub from a SUB 2.1 Soundbar, I Had the same amp but with a Crossover Freq knob. I ran it with a 19v 3.5a Laptop Power supply. It's great and makes my 4" KRK Speakers sound like they should. Only downside is the Thump with power off, but I will fix that.
The input limit reaches 3v same as the tpa3118 full range mono. Phones or rca's cant fully drive it even if it is at the max voltage of 26v. Unless your stereo can push more than 500mv on plugs. I have one tpa3116d2 full range stereo amplifier with signal booster that I modified to no hizz, for my homemade Bluetooth speaker with a dewalt battery and Bluetooth module and a dc-dc voltage booster 12-26V. Also I replaced my Yamaha amplifier with 2 TPA3118 mono block boards dc-dc voltage booster 12-24V driving 2 shelf book speakers sharp CP-C3900 150Wrms and they thump... Happy with both systems.

Great job! I bought this same amp, and it arrived today, because of this review. Playing around with it first before I get another to hook up to D4 VC 8s to add a stereo bass setup to our home theater. Thanks!
That is what I just built! Did a vid on my channel. Running a 2-channel version of this 100w amp with dual TPA3116 chips. Using a DC-to-DC booster off my lithium battery to bump up the volts to 24.00v.
Buy tpa3116 boards with larger inductors! Gives usally less distortion and check out the forums to find out which versions who has no hiss! Properly designed boards with this chip sounds really good!
I'm running my system off the stereo version that uses the same chip, I built it into a cigar box. It sounds clean and provides ample power, I paired it up with a Chinese tube preamp and they sing.
Don’t forget they run best if your power supply has adequate amps as well . Anything under 3.5 amps really won’t be powerful enough and will effect the performance of the amp board
Yo BigD, nice video as usual, hope you'll get around to doing some more cheap stuff videos. It's great seeing the cheap stuff getting so close to rated power. Someone asked about running it on batteries, I got something like that going in a salvaged parts project, but while it makes a lot of noise, its quality is laughable, all reused broken parts. I would make a video but I higly doubt anyone would be interested. You said something about retiring in a comment response, are you that old? you don't seem like it, maybe you were talking about the later future and I misunderstood. Anyway, cheers and keep making great videos for as long as you can, you're doing a great job!
Might be 5 or 10 watts more available as the 100w was at @ 26 volts whereas the test was using 25 volts. I ordered this little Class D amp for a 6 inch portable subwoofer
Given that "TDA" is a common prefix on other amplifier ICs, it's likely that "TDA3116" refers to the actual IC (as indicated on the silkscreen on the PCB), and TPA3116 refers to the whole module (or may have been a misprint.)
Probably just a mistake. TDA is a common series. I would easily mix up Chinese characters when I had to put them on a board. I suppose that happened here as well.
I really enjoyed the video. I was just testing one of these today made by sure electronics that I got from parts-express. They work surprisingly well, especially for bass shakers. Will have to give this one a try for my subs!
I've been watching another RUclipsr JohnAudioTech test these little amps for a while and have not seen him do the TPA3116 amps yet and I love playing with unique amps, so I decided to pick up a few. I must say, the 2.1 models seem to be a perfect match for a custom boombox. This one I tested here would power a 6.5 or maybe 8" sub well for a small room.
lol, I like the make line on your results sheet @8:40 "some chinese dude". Nice video. The tda3116 is the name of the board, and tpa is the chip as there are no tda3116 ic's that i've ever heard of.
Hi, im a big fan of your old school amp tests! Love the old Hifonics 👍 got a question for u, have u ever tested the Directed amps? i would love to see the old Directed 2400d from early "2000ish" om the dyno! u know if they are any good? Keep Up the Good work!
Thanks for the video. For what wattage is the power supply that didn't work rated? I found the exact same on eBay and thought maybe I'd better buy a more powerful version than yours. Also, did you experience any overheating issue?
+konnichy it would shut off at 5A of current pulled at 24 volts. When I contacted the eBay seller it was like they were not surprised. I only ended up paying about $5 after the refund, but a bit bummed as it was supposed to be a 20A, 24 volt power supply. Overrated fo sho
Nice video man. Want to say thank you for your quick response and input. I thought of you got instantly when I came across it. I did not take it home. I appreciate it a lot.
The power connector that they use will drop voltage for sure. Also the filter inductors they use are another weak point. The TPA3116D2 is becoming one of my fav chips for these cheap amps. It just sounds decent for the prices paid.
That fuzziness near the peaks on 2 Ohms, is the result of current limit, and core saturation of the 22 uH inductors. you're peaking about 12.5 amps on inductors rated for 10 amps, and I don't even know what the peak current limit is on the TPA3116D2 chip is. I can't seem to download the data sheet on that device. The closest I can get, is that the amp requires a 3.2 Ohm load, with 26 volts, to achieve 100 watts RMS, without clipping. That would put you right at the current limit rating, and, high enough voltage to get that wattage without clipping. Too low impedance, current clip. Too high impedance, just won't draw the necessary current without voltage clipping.(current clipping looks ugly on the oscilloscope)
Class D, 94W into 2 ohms with 6.5 amp draw - so a quick calc: 24V x 6.5a = 156W. Not quite class D efficient eh? Seems little better then the average ebay amp though, esp at $12.
The dynamic tests are tough to get accurate current pulls. The new Fluke clamp meter I got has an "inrush" mode which averages the very fast peaks and all I can say is seeing 6.5a or more pulled from this amp would be a rarity.
Your very right that it's hard to really measure those spikes. But the cert test does tell the story efficiency. Hmm, think it's possible that the 100W rating is total power draw as opposed to power out?
That would be a strange way to rate, but seems to be the case. The spec sheet I found was not detailed on the wattage output or distortion in any detail at all. I must say, they are getting better on ratings though. The amps I tested years ago said "500 watts" and put out less than 20 watts...
I bought 6 or 7 of them, many were the 2.1 models (rated 50x2 and 100x1). Some were RCA input only, others were 1/8" input only and a couple are BT only. I've noticed the BT models have noise issues. I guess it should be expected for a $15 amp rated 50x2 and 100x1 with built-in Bluetooth module! I'm going to probably compare the similar amps, will test them all, but most likely not individual videos. I guess it really depends on the popularity of the videos and how many people want to see these amps.
Thanks for testing these! I was thinking about building a bluetooth ottoman, looks like 36v and a "50+50+100watt" will push mids, tweets, and a dedicated sub very well! what was the draw at 24v?
+Chris Lesmerises most of the TPA3116 based 2.1 amps want about 25v max (be careful as some have 25v caps, most should have 35v). Current draw on sub channel was around 4 amps at clipping
I know it's not quite apples to apples, but I'm looking at a 36 volt 2.1 Bluetooth board :) Thank you for keeping notes, you've surely saved me an R&D revision, at the least, saved me some test parts!
+Chris Lesmerises I just got a 32v version using the ST508 chip and is rated 80x2 and 160x1. I bought about 7 different models of the amp boards. Most were TPA3116, but a few were different. I've noticed the BT models are a bit noisy. There are mods to lower the input gain. Still amazes me what you can get for so little $$ 🤔
Hey Big D! I'd love to see a Dyno test of the Tripath TK2050, supposed to push 50w two channels. Also, peaking on it doesn't sound harsh, while the TPA3116 sounds terrible. Just my observation.
Powerful little amp! I'm looking for an amplifier like that only stronger ... Do you know a stronger model than that? 150-200w Want to build a subwoofer just for fun lol
Yes, there are 2.1 versions, 120x2, 210x2 and even 500 and 600x1 boards. But the bigger the board, the bigger power supply required (and high voltage also). You will spend more on the power supply than the board in some cases
I was considering using one of the old Jensen first generation 4400 amps as a power supply (since the power supply is separate from the amp board with only 4 wires connecting them), and using whatever board was voltage compatible with the output (+28/-28 volts). it would have to do better than the original TIP 35/36 setup they originally had or it wouldn't be worth the effort.
This particular model has a low-pass filter and is designed for low frequency speakers only. There are several other models including 50x2 models that would work great for the two 6.5's (and the amp is full range)
I have the Nobsound NS-08G TPA3116 2.1 amp its a much different build to this amp and id say it quite powerful as im using 2 Q acoustics 15-75w speakers and one sony subwoofer from a 5.1 system and that's rated for 130w rms and this amps really uses all of the subwoofers potential at 24V At 5amps so much so I can bottom out the subwoofer quite easily without even maxing out the amp especially using a tuned equalizer this with the subwoofer volume set to 40% on the amp also and around 45% master volume power and the speakers gets used quite well also can max out these speakers without any distortion.
Hey BDWyz, love the channel & all the hard work you put into videos! But would this work on a Polk 10"sub with a blown stock plate amp? Was a great sub but I'd like to add it to the shop stereo in my woodshop?
BigDWiz- Thank you for your time & help! But how would I connect this sub amp to a amp without a sub out. Should I use a 3.5mm cable with a double end...? From source to 1amp & 1to subamp. I used to run the speaker wires through the Polk sub when there was no sub out on the amp I was using. Found the board on amazon for s11&change. I can't wait! My first build!
Is this output bridged from 2 channels on TPA3116? Little low power on 19V input for bridged mode but I might be wrong. What is the roughly cut-off frequency on the low pass filter on this? Thanks for the review. It is awesome.
i have one but its a 2.1,and i play It on a pair of 3 way Tower speakers that are probably 50w RMS each,and a 2000w digital designs subwoofer,that one is my dad's sub,and my own sub is a 50w LG subwoofer with a custom build box
+the Forza guy I got several more of these to try out, including a few 2.1 models. I plan on testing them all and going over pro and cons of each model
I have a 4 inch subwoofer that’s rated 20 Watts 4 ohm. What voltage do you think would be best at getting the most out of the subwoofer without blowing it when I crank the volume.
I’ve heard people say this before and I have no idea why this is happening. Maybe it’s your wife/girlfriend not wanting you to watch vids of amplifiers 👈😊
Do you think this is powerful enough to drive 2 x 8" or 2 x 10" subs in parallel @ 2 ohms at moderate listening levels when used in a personal 2.1 system for music/gaming? (not planning on using for entertainment or turning it up loud).
Can I use a similar amp like that to put in a smart speaker that stopped working? It's already wired for a battery pack and 18v plug in power. An Altec Lansing Stream X speaker... it just stopped working one day. I figured maybe just wire one of those up to the speakers and battery pack and power input from the cord and it should work??? I'd like to find one with Bluetooth and about 30 Watt
sir, i attached 10" subwoofer 200 wats with this device and 24 volt and 3 ampere adaptor. but when I am increasing the volume the indicator light of this device is blinking some time became light and high, and subwoofer is creating pop sound. should i use 6 amper adaptor to get rid of this problem. please solve my problem.
I don't think it particularly matters if this chip will actually reach the specified power at 10% THD, because 10% THD is so distorted, nobody would want to listen to it anyway.
I really want to know the true power of the Bluetooth amp board from Parts Express. Made in America so they run much more expensive than the Chinese ones, but are they worth it?
So, 24V and 5A power supply should be ok for this amp @ 2ohms right? 2 speakers @4 ohms in parralel . And if i add an 4700uF capacitor or maybe more, for peak amps? Thanks, waiting for your answer :D Greetings from Romania !
+Dragosh Remus hello sir! Yes, that power supply should suffice, although it may give run out of steam when pushed to its limits. Make sure that 24 volt power supply really puts out 5 amps as some are overrated. I will check this amp again and measure current pull and let you know for sure
If I wanted to power a Subwoofer and wanted more power than this item - what can u recommand - and that does not brake the bank. I have a passive Subwoofer i need to power and was going to use this item... but its not really going to push anything... can u help me find somthing that is 100W
Have you ever thought about taking these cheap little Chinese at and strap them together to see how many of them you can get into a daisy chain to basically get a larger powered amp

The power connector that they use will drop voltage for sure. Also the filter inductors they use are another weak point. The TPA3116D2 is becoming one of my fav chips for these cheap amps. It just sounds decent for the prices paid.
Great demo/video...thanks.
Thanks for watching and commenting!
That fuzziness near the peaks on 2 Ohms, is the result of current limit, and core saturation of the 22 uH inductors. you're peaking about 12.5 amps on inductors rated for 10 amps, and I don't even know what the peak current limit is on the TPA3116D2 chip is. I can't seem to download the data sheet on that device. The closest I can get, is that the amp requires a 3.2 Ohm load, with 26 volts, to achieve 100 watts RMS, without clipping. That would put you right at the current limit rating, and, high enough voltage to get that wattage without clipping. Too low impedance, current clip. Too high impedance, just won't draw the necessary current without voltage clipping.(current clipping looks ugly on the oscilloscope)
Class D, 94W into 2 ohms with 6.5 amp draw - so a quick calc: 24V x 6.5a = 156W. Not quite class D efficient eh? Seems little better then the average ebay amp though, esp at $12.
The 94W measurement was dynamic though. The certified test 2 ohms was 25v x 4a = 100W...measured 85W, so 85% efficient
BigDWiz Okay, a lot more effecient then I thought.
The dynamic tests are tough to get accurate current pulls. The new Fluke clamp meter I got has an "inrush" mode which averages the very fast peaks and all I can say is seeing 6.5a or more pulled from this amp would be a rarity.
Your very right that it's hard to really measure those spikes. But the cert test does tell the story efficiency. Hmm, think it's possible that the 100W rating is total power draw as opposed to power out?
That would be a strange way to rate, but seems to be the case. The spec sheet I found was not detailed on the wattage output or distortion in any detail at all. I must say, they are getting better on ratings though. The amps I tested years ago said "500 watts" and put out less than 20 watts...
Does not ship to South Africa :-(
Hope you found a solution, alliexpress has a million
awesome video man you should definitely do more of those amps
I bought 6 or 7 of them, many were the 2.1 models (rated 50x2 and 100x1). Some were RCA input only, others were 1/8" input only and a couple are BT only. I've noticed the BT models have noise issues. I guess it should be expected for a $15 amp rated 50x2 and 100x1 with built-in Bluetooth module! I'm going to probably compare the similar amps, will test them all, but most likely not individual videos. I guess it really depends on the popularity of the videos and how many people want to see these amps.
+BigDWiz I would want seeing more cheap stuff.
BigDWiz well I'm very interested
Thanks for testing these! I was thinking about building a bluetooth ottoman, looks like 36v and a "50+50+100watt" will push mids, tweets, and a dedicated sub very well! what was the draw at 24v?
+Chris Lesmerises most of the TPA3116 based 2.1 amps want about 25v max (be careful as some have 25v caps, most should have 35v). Current draw on sub channel was around 4 amps at clipping
I know it's not quite apples to apples, but I'm looking at a 36 volt 2.1 Bluetooth board :) Thank you for keeping notes, you've surely saved me an R&D revision, at the least, saved me some test parts!
I'll sign the inside of the T-line port "BigD" for ya
+Chris Lesmerises I just got a 32v version using the ST508 chip and is rated 80x2 and 160x1. I bought about 7 different models of the amp boards. Most were TPA3116, but a few were different. I've noticed the BT models are a bit noisy. There are mods to lower the input gain. Still amazes me what you can get for so little $$ 🤔
Hey Big D! I'd love to see a Dyno test of the Tripath TK2050, supposed to push 50w two channels. Also, peaking on it doesn't sound harsh, while the TPA3116 sounds terrible. Just my observation.
Great info! I'm just getting in all of the little amps I bought, so I'm testing them out when I have time.
Sweet! Can't wait!
Powerful little amp! I'm looking for an amplifier like that only stronger ... Do you know a stronger model than that? 150-200w Want to build a subwoofer just for fun lol
do they make a bigger or more expensive board ?
Yes, there are 2.1 versions, 120x2, 210x2 and even 500 and 600x1 boards. But the bigger the board, the bigger power supply required (and high voltage also). You will spend more on the power supply than the board in some cases
I was considering using one of the old Jensen first generation 4400 amps as a power supply (since the power supply is separate from the amp board with only 4 wires connecting them), and using whatever board was voltage compatible with the output (+28/-28 volts).
it would have to do better than the original TIP 35/36 setup they originally had or it wouldn't be worth the effort.
that is a GREAT idea ! i have a couple old jensen's with dual board also .
Hey..!! I have two woofer 4ohm, 20w each. Can i series it with this amp to make a cheap boom box?
datasheet says 120w mono at 1% thd with 24v supply. so i suspect your leadacids were voltage sagging underload.
Data sheet for the chip and we’ve seen these underperform before
thanks for the video Big D. know what's funny is that little amp did better than the pyramid amp you tested a while ago.
Now that's a hoot!
How about a shoot out? Lol.
Does this play full range as well? Would be cool make a portable system with a pair of 6 1/2's with this amp.
This particular model has a low-pass filter and is designed for low frequency speakers only. There are several other models including 50x2 models that would work great for the two 6.5's (and the amp is full range)
I have the Nobsound NS-08G TPA3116 2.1 amp its a much different build to this amp and id say it quite powerful as im using 2 Q acoustics 15-75w speakers and one sony subwoofer from a 5.1 system and that's rated for 130w rms and this amps really uses all of the subwoofers potential at 24V At 5amps so much so I can bottom out the subwoofer quite easily without even maxing out the amp especially using a tuned equalizer this with the subwoofer volume set to 40% on the amp also and around 45% master volume power and the speakers gets used quite well also can max out these speakers without any distortion.
Great video! I'm new to board amplifiers, which is best plate amplifiers or board amplifiers for sub woofers. Not based on price. Thanks
I've been curious about these, thanks D!
+motoman22atgmail me too! I figured a few peeps out there might be curious as well
Another great video,
How hot did the amp get?
cheers
+08ds it was warm, but not hot to the touch. I'll measure temp and let you know
What the benefits of using battery to power this board instead of ac-dc power supply?
Can't believe that thing moved that sub at 10hz! My four 8 inch American bass subs and jbl 1001ez won't flex like that at 10hz!
Hey BDWyz, love the channel & all the hard work you put into videos! But would this work on a Polk 10"sub with a blown stock plate amp? Was a great sub but I'd like to add it to the shop stereo in my woodshop?
It should do ok with your Polk sub. For $10 seems worth it to try 🤷♂️
BigDWiz- Thank you for your time & help! But how would I connect this sub amp to a amp without a sub out. Should I use a 3.5mm cable with a double end...? From source to 1amp & 1to subamp. I used to run the speaker wires through the Polk sub when there was no sub out on the amp I was using. Found the board on amazon for s11&change. I can't wait! My first build!
You think an amp based on this would be ok for 2 atmos speakers? Or better go with the TDA7498E
Is this output bridged from 2 channels on TPA3116? Little low power on 19V input for bridged mode but I might be wrong. What is the roughly cut-off frequency on the low pass filter on this? Thanks for the review. It is awesome.
Great video DI'd like to see these tested 300W Class D IRS2092 IRFI4019H IRAUDAMP7S Amplifier kit L15D LJM purchased on fleabay
Explains why it works so well on a m18 battery CURRENT!
perfect for PC speakers
I really like the video. there's a tonne of these cheap amps on fleebay and good to see what is worthy allways a thumbs up from me bigD
i have one but its a 2.1,and i play It on a pair of 3 way Tower speakers that are probably 50w RMS each,and a 2000w digital designs subwoofer,that one is my dad's sub,and my own sub is a 50w LG subwoofer with a custom build box
+the Forza guy I got several more of these to try out, including a few 2.1 models. I plan on testing them all and going over pro and cons of each model
Hey Big D Wiz . Love the show. But I was wondering have you ever had any Sherwood amps on the dyno ? Now that's a old school amp
I have not yet, but those were budget amps and most likely right at or just below rated.
Yeah I remember them. I had a neighbor that had two 240 watt Sherwood amps on two Cerwin Vega 12 in. subs
excellent presentation man! thanks
+MR Moon thanks 👍
please do more test from tda line like tda8950 tda7294 tda8920 tda7498 and sta516b rated @ 200wpc 400w bridge
and please do test on receiver amp like technics harman kardon and denon and other brand
will This Work ok On a 2ohm 250WRms 1000W max 12inch Subwoofer ?
I have a 4 inch subwoofer that’s rated 20 Watts 4 ohm. What voltage do you think would be best at getting the most out of the subwoofer without blowing it when I crank the volume.
Big D idk what's going on but RUclips un-subscribed me from your channel🤔 I just noticed and resubbed.
I’ve heard people say this before and I have no idea why this is happening. Maybe it’s your wife/girlfriend not wanting you to watch vids of amplifiers 👈😊
Is there a new Cheap mono board good for subwoofers that has taken the crown?
Do you think this is powerful enough to drive 2 x 8" or 2 x 10" subs in parallel @ 2 ohms at moderate listening levels when used in a personal 2.1 system for music/gaming? (not planning on using for entertainment or turning it up loud).
$12? How is that even worth the effort of making that amp? Very good value.
+zzzACE73 zzz it was actually under 10 dollars...shipped 😱
Can I use a similar amp like that to put in a smart speaker that stopped working? It's already wired for a battery pack and 18v plug in power. An Altec Lansing Stream X speaker... it just stopped working one day. I figured maybe just wire one of those up to the speakers and battery pack and power input from the cord and it should work??? I'd like to find one with Bluetooth and about 30 Watt
xD the brand of his main amp is SMD
sir, i attached 10" subwoofer 200 wats with this device and 24 volt and 3 ampere adaptor. but when I am increasing the volume the indicator light of this device is blinking some time became light and high, and subwoofer is creating pop sound. should i use 6 amper adaptor to get rid of this problem. please solve my problem.
I don't think it particularly matters if this chip will actually reach the specified power at 10% THD, because 10% THD is so distorted, nobody would want to listen to it anyway.
Nice ! 👍
Great with adapter for my power tools 18/20 v batteries.
Good video, good explanations...
+masterjumpstyler1 thanks for watching and commenting 🤙
what if I wanted to make it portable. could I use rc batterys.and could ya make a video of that? please
I been meaning to say it, about time you threw your Kline away and got a Fluke! I got my Bluetooth one loving it!
I didn't throw it away, but yeah, that Fluke is the bee's knees! I should have invested in long ago
How hot did that little heat sink get ? That's not to bad for less than $10 and that chip being so small doing all that.
Barely got warm during the test. It appears this heat sink is WAY oversized based on the ones I've seen on similar TPA3116 chip amps.
if im gonna use it for 1 single subwoofer,how big and how many watts of a speaker can I use on this?
Anyone have a problem with the poor suppression of interference from the power supply? Anyone fixed this specificaly with this board?
For this type of amp what is the minimun watt woofer spec should i buy, I already have one woofer but not enough for this amp to play
Can you do one 1ohm ans one 0.8ohm test please ?
one channel 25volt 3Ampera 55wat. two channels 25 volt 6 amper 55+55 wata ?
test please the number 5 an please test the American Audio DJ PA 2500 with 2x 1.2kw at 4 ohm
shit amp
I really want to know the true power of the Bluetooth amp board from Parts Express. Made in America so they run much more expensive than the Chinese ones, but are they worth it?
I don’t believe any of the chips are manufactured in the US anymore
So, 24V and 5A power supply should be ok for this amp @ 2ohms right? 2 speakers @4 ohms in parralel . And if i add an 4700uF capacitor or maybe more, for peak amps?
Thanks, waiting for your answer :D
Greetings from Romania !
+Dragosh Remus hello sir! Yes, that power supply should suffice, although it may give run out of steam when pushed to its limits. Make sure that 24 volt power supply really puts out 5 amps as some are overrated. I will check this amp again and measure current pull and let you know for sure
I would also like to know because I also have 24V 5A power supply and I wonder if it is sufficient for peak power.
Thanks for this
If I wanted to power a Subwoofer and wanted more power than this item - what can u recommand - and that does not brake the bank. I have a passive Subwoofer i need to power and was going to use this item... but its not really going to push anything... can u help me find somthing that is 100W
Now we know what's inside Bose home theater!
👈😜
Have you ever thought about taking these cheap little Chinese at and strap them together to see how many of them you can get into a daisy chain to basically get a larger powered amp
+VdubSPAZ lol, yeah, thinking about a home sub build using one of these
