$10 Subwoofer Amplifier? TPA3116 Amp Dyno Test

Просмотров 179 тыс.

% 2 132

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!

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

@wal 7 лет назад

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

@PixelUser 7 лет назад

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 watching another RU-vidr 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.

@claysonwebster1622 7 лет назад

awesome video man you should definitely do more of those amps

@wal 7 лет назад

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.

@AgribusinessDR.G. 7 лет назад

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.

@wal 7 лет назад

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

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!

@jeffm2787 3 года назад

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.

@maine420247 6 лет назад

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?

@wal 6 лет назад

It should do ok with your Polk sub. For $10 seems worth it to try 🤷‍♂️

@maine420247 6 лет назад

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!

@williamsquires3070 7 лет назад

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.)

@pizzablender 4 года назад

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.

+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

Thanks! The 12V batteries in series give me at least 10A of available current.

@djohnnineonesix820 3 года назад

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.

@wal 3 года назад

My source unit has over 4V of clean output, but your point is valid for those using headphone jacks and such

@roblc11 6 лет назад

+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 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

Anyone have a problem with the poor suppression of interference from the power supply? Anyone fixed this specificaly with this board?

Would it be wise to use a 20v 4.5 amp power supply for this amp for home use? What do you recommend?

@SoXDYTB 5 лет назад

this is great , but if u want the maximum power just use a power supply that can do 26v 10A and you will not have any problem

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.

Are there any better but little more expensive alternatives to this sub amp?

@wal 6 лет назад

Yes, but they require expensive power supplies. At that point you’d do better getting a plate amp

I have a question please? Is it possible to connect 2 of this amp in parallel to get 200watts output? Not an electronic guy here, just want to learn something 😅
