$10 Subwoofer Amplifier? TPA3116 Amp Dyno Test
ฝัง
- เผยแพร่เมื่อ 3 ก.ค. 2024
- A few years ago, I tested several inexpensive amps bought off eBay and found there were crazy claims made with unimpressive results. Recently, I've noticed a new batch of inexpensive amp boards, yet this time with more reasonable claims. I've purchased several amps I'll be testing in upcoming videos, but first up is the $10 TPA3116 mono subwoofer amplifier. Yes, I said $10...including shipping! This amp is rated to deliver 100 watts to a 2 ohm subwoofer. You know how we roll, let's see what this amp is all about!

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?
bought, what a neat little thing!
I love your amp dyno videos, great channel
Thanks man!
BigDWiz nice D..I just bought a TPA3116D2 100wx2 its on his way can't wait to do my 1 of 2 projects Boombox?
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 TH-cam. I can't thank you enough for this video man lol thanks
Cool man, glad the video helps 🤙
please do more tests of ebay chinesieum amps. There is plenty of interesing ones that I would love to see! Thx
Forthcoming!
Chinesieum! Will it chooch?

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!
Interesting little amp. I've been wanting to test one on my bench. The budget audio guys seem to like these TPA3116 based amps.
+JohnAudioTech does your power supply adjust up to 24 volts? I wish I had a cool o'scope like you have
I know a Amazon store,the Subwoofer Amplifier TPA3116D2 Amplifiers also well,AOSHIKE brand
+JohnAudioTech Yes John please do!
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.
Cool vid, I appreciate the variety Big D!
Thanks for watching and commenting 👌
I'm glade I found this channel... will be watching many more of your videos.
Glad to have you here, thanks!
Every time you say "OLD SCHOOL!" I make sure I am subscribed. Never change!

That's the boombox amp I've been looking for!
Get the 2.1ch version instead. It's only a few $$ more and is an even better value
Building one with cheap 5 inch components and an almost 8 inch sub, total cost like 50-60 bucks, hpe it will sound good
cesare vissani that's about what I'm going for.
Already tested the stuff withouth a box and it's pretty loud, hoping to get it better with a proper box
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.
+Derek Sr. 👍
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!
Awesome! Great to have you join us 👌
thank you for the video! and keep in mind u can get decent high voltage charges for a dollar or 2 at goodwill and other thrift stores!
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.
I've been curious about these, thanks D!
+motoman22atgmail me too! I figured a few peeps out there might be curious 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!
Cool 4real it's perfect for a motorcycle
I've been watching another TH-camr 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.
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
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
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.
Great demo/video...thanks.
Thanks for watching and commenting!
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
this amp out-performs that pyramid shadow amp you tested earlier
Crazy right? You could probably fit 5 or 6 of these in that heatsink also
tweco knight betatl
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 😆
excellent presentation man! thanks
+MR Moon thanks 👍
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.
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
Good video, good explanations...
+masterjumpstyler1 thanks for watching and commenting 🤙
Is that NAD s final..? I could really find an sweet spot for her, among my old C350.. :D
Keap makeing good videos WAL..!
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.
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!
Nice ! 👍
Great with adapter for my power tools 18/20 v batteries.
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.
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.
I love these tests, I make pawnshop scores based on the tests.lol
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
Some TPA3116 mono specs: Power output (w/ 21 VDC power supply): 100W x 1 (2 ohms, THD 10%), 87W x 1 (2 ohms, THD 1%) pretty close to me.
Hey BigD! Last week I got PPI-2150AM from local crassfields for only 12$! And it's in perfect working order!
It's the bargain of the century!
+urosb82 now that is the deal of the century fo sho 😱
urosb82 paid 400 for mine in 1993
Hope you hold on to it all these years. I got it stupid cheap (white series with artwork) to the point I almost feel guilty...
Great video DI'd like to see these tested 300W Class D IRS2092 IRFI4019H IRAUDAMP7S Amplifier kit L15D LJM purchased on fleabay
Thanks for this
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!
+HenkeB20 I haven't tested any Directed amps yet, but have heard good things about them
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.
Keep doing great video like this one
+Georges Obeid I have a ton of mini amps to finish testing, thanks for watching
Great video! I'm new to board amplifiers, which is best plate amplifiers or board amplifiers for sub woofers. Not based on price. Thanks
awesome, I've been building with these.
That thing would be great for a 6.5 inch sub on a boombox setup.
Exactly what I thought
Efficiency is king here, so something like the Goldwood GW-410D would rock with that amp.
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.
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
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!
You sound like the "Track 6 - woofer excursion test" track
+MoonBlade don't steal my thunda 🤔
Kinda does huh
@@wal Drop Bottom, Dropbottom dropdropdropdropdropdrop Dropbottom, Drop Bottom Drop Bottom (consider this a warning muthabrutha) 😆 any 90s bass head will know this track. For those that don't, its power supply second album more bass more boom more bottom, the song is, you guessed it....Drop Bottom
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
Nice video. Super amp for the price. Your chart would be a lot different if you used a 24V 8a AC/DC power supply. Much higher wattage.
Thanks! The 12V batteries in series give me at least 10A of available current.
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
Hey..!! I have two woofer 4ohm, 20w each. Can i series it with this amp to make a cheap boom box?
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!
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
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.
I put a small amp like this in my logitech sub when its board went bad. And it would overheat when the volume was too loud so I put the little amp in the speaker's port so air would blow over the heatsink XD and that actually solved the problem lol
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).
You think an amp based on this would be ok for 2 atmos speakers? Or better go with the TDA7498E
so, what more important?
the voltage or the current of the power supply?
It's both.
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.
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)
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
This would be a good amp for tactile transducers.
+D4rk51d332 I bet you are right
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!
+impuls60 I've noticed the units without the BT modules seem to sound best. But yes, they have impressive sound 👍
What the benefits of using battery to power this board instead of ac-dc power supply?
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
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
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.
Lol i got the exact same model as a subwoofer amp. Paired with a hollywood hesa 12 with a 8 ohm 12" kevlar subwoofer. Btw im using a 19v laptop power supply, in my car im using a 12v to 24v 10A step up converter.
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
nice still be nice to se the behringer ep 4000 or 2000
will This Work ok On a 2ohm 250WRms 1000W max 12inch Subwoofer ?
It would be good to use for a computer 2.1 sound system
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.
My source unit has over 4V of clean output, but your point is valid for those using headphone jacks and such
I have this for my bass shakers on my couch
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
Wish u would do Memphis 1000d
What does it sound like?
Is there a new Cheap mono board good for subwoofers that has taken the crown?
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 $$ 🤔
Damn dat shit bumpin
😜👍
Are the 15$ 24v power supply good enough?
xD the brand of his main amp is SMD
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
Shocked anyone could produce and amp for $10.bargin of a lifetime. 👍
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
Yeah I'd probably use this for a small boombox speaker, throw a 150w speaker on there and get some jams
When are you going to do a old school powered EQ amp dyno?
+Jesse Wise the last one I tried would not measure properly b/c it wanted speaker level inputs and all of my test head units are setup for RCA outs only.
it's a nice amp I would like.to buy a few for highs and mids
This one has a crossover and does low frequencies only. There are 50x2 and larger full range versions out there, just note the voltage they require to reach full output. Most require 24 volts, some require 32 or even over 40 volts depending on the model.
Kool thanks for the heads up man I luv your videos and I always will the amps bring back so many memories and u have really good content and unknown hard work gets put into making them
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.
Hi do have a video of the tpa3255 and the tas5630?? Can you test them on your dyno pls
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!
me gustan tus vídeos de la vieja escuela, yo soy DJ REY from te 80" to now! y Í AM a Base lover! Andrea forma That Price, no puedes pedir más!
Can you test the xh m190 v3 in 12v and max volts ? I will make this in my car for the doorboards...
Nice - but how do i connect one of these - to fx a bluetooth tda7472p blutooth amp ...is it possible ??
Big D idk what's going on but TH-cam 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 👈😊
what if I wanted to make it portable. could I use rc batterys.and could ya make a video of that? please
Yo big d! Do you think you have the ability to dyno a concept cc-d2400a??? I've had one pushing four alpine type r 12's for about 12 years now. Can't believe the reliability on both sides. I've read online it's half ohm stable but can't find any real specs and unfortunately threw the manual away years ago and can't remember. Thanks man.
