Which subs you think to go with 2 10 g2 dynamics genesys or 2 x10v3 sundowns

[@taracushingberry1]

🤔

[@thatautogarage3644]

Please build a tiny vented or ported box for those 1.5" subs. After that's completed take it to the next audio competition and demand they score your setup to scale!

[@r-ratedstudios3847]

why do you call an RC speaker a sub ? u take us for dumbfucks bro ?

[@one1onetime935]

$29 now

[@LowLevelNC]

Big D, I've got the inside scoop on that amp and subs. They were developed in collaboration with the Geico Gecko. He's branching out into car audio. 15 minutes could give you 10 watts or more.

[@chrispello5487]

😆😅🤣

[@Werewolfmage]

hahaha

[@Van1018s]

Nice. lol

[@RyanBassForLife]

Haaa😂

[@CRGMONEY]

Does he insure it if it burns to the ground? Lol

[@williamvonroenn8063]

I want to see the tiny subs in a box!!! Do it bump doe?!?! BOX THEM UP!!!

[@bozanimal5576]

Tiny amp, tiny sub, giant bandpass box. In a push-pull. With a passive radiator.

[@Bassotronics]

In individual solid pvc tube t-lines.

[@1pcfred]

With no flange on the frame how do you even mount those tiny speakers? Glue? There's nowhere for screws. But yeah an enclosure makes a bigger difference than you'd think with speakers. Any enclosure. Heck even just a board. The problem is the sound waves off the back of the cone cancel out the front ones. It's weird. You need to separate the front of the speaker from the back somehow.

[@bozanimal5576]

​@@1pcfred They're press-fit. The hole needs to be precision cut then you glue them in.

[@1pcfred]

@@bozanimal5576 gluing speakers in is a somewhat crappy method especially in a DIY application. I'm more than capable of cutting precision holes with the tools I have. Generally I just use a router and a custom made circle cutting jig. I know how to do all of that. How to do the calculations so it works out. Although today I do happen to have a CNC machine too. It's repeatable to within a thousandth of an inch. Still, I view having to glue speakers in as lousy. What do I do if I ever want to take the speaker out? Hammer and chisel? Yeah I don't think so.

[@fishyfool]

I'd be impressed if the tiny subs were in a boxed enclosure with a bandpass port. My Harmon Kardon bluetooth (Onyx studio 4) speaker has two 3" subs and 15 watts per channel and it does thump.

[@erichill7560]

get 25 of those long throw bad boys and slap 'em together on a box

[@FrostyTerps21]

Nobody's tryna impress you bro

[@macromage]

what if instead u made them into open back headphones, that'd be nuts but also mad fun to listen to

[@spankthemonkey3437]

I used to do this with head phone speakers in my model cars as well as "hydraulics" too back in the late 90s🤣

[@TimpBizkit]

A big horn enclosure as it's more even in its boost than a bandpass.

[@HamidNazemi-YT]

I replaced my Toyota Tacoma's original speakers with more powerful ones and used this tiny amp to power the rear speakers. The Amp installation was a piece of cake. Now I have a much better sound in my truck to enjoy. So far, so good!

[@captanspace]

Here in brazil, we use it to power the compression drivers. The guys here use woofers to play from 30hz to 1000hz and compression drivers with exponential horns for the rest. Since they have an insanely high sensitivity with only 40w, you can get 110db at 6m. And yeah, they only do it to be loud. They have 0 sound stage, 0 imaging, and the dsp isn't even calibrated. They just look up a generic video on youtube on how to set it up, just to protect the compression drivers😂.

[@gabrielv.4358]

Nice! um BR! Thanks for sharing

[@CaptainNero]

Looks like it was fun making this video with those mini subs. Definitely made me smile watching the mini subs bump and flex.

[@deciplesteve]

This would be amazing in a kid's power wheels. The Bluey soundtrack would be perfect for this.

[@theaudioasyulm]

Excellent test D, I remember a similar amp to this shown to me by a distributor in the 90's, It was TINY! It was supposed to be used at each door, effectively giving multi channel, passively split amplification. I always thought they were cool. This amp with simple wiring and auto turn on would work really well biamping a mid and high through a bi ampable crossover.. Imagine having 4 of these, one on each corner. It would sound great!

[@arcademania7544]

Wasll are

[@BlueDinnie]

The fact that you can get 90 Watts out of something this small when 20 years ago the thing would have been The weight of an Escobar shipment is ludicrous. 😎

[@josue_kay]

Yup, the magic of class D digital amps and neodymium speaker magnets 👌

[@erichill7560]

SCIENCE!

[@MrBonger88]

Escobar shipment. Lol, love it

[@West3rror]

Except for the fact that this actually will NOT give you anything glose to 90 real watts... There is a difference between messuring weak watts and real watts with actual current/amps behind them. I have seen many 50-100w amps eat 200-300 wannabe watt amps for lunch. It's basicly the same as with horsepower and newtons on a engine... 100 HP with i.e just 10 NM would be pretty worthless...

[@joerunyon5824]

I've love if you could 3D print a sub box for those mini-subs to really give them a proper demo.

[@Iowa599]

Should have a 3.5mm high-level input… It makes as much power as a head unit, so it should be ready to use with other portable audio sources.

[@Manic1578]

The only problem is it has now low-level input.

[@ATSNorthernMI]

These are really noisy amps if they aren't filtered correctly. You really need a good charger that doesn't introduce charging noise. I have a few of these TPA based chips in various amplifier boards, that I used to build a distributed audio system for my house. I use a head unit to power the 4 speakers in the dining room ceiling, a cheap class d based mono block to power a 12" older sony xplod sub and the tpa amps power the bathroom speakers and porch speakers. The cheap 20 dollar walmart head unit has good enough filtering but the TPA amps don't and they have terrible hiss and "data" noise in them. It's ok when you're cranking on them but they won't be silent with nothing playing.

[@yahnsolo]

there is only network of resistors and capacitors to adapt speaker high level input before attacking the TPA's balanced inputs (i suppose the LM393 is there for the signal detection for the power on; not for input stage of the TPA's). So for a 3.5mm input, this is absolutely possible and easy to add low level/highZ input, just picking up the inputs on the correct place. Also keep in mind that the frequency response is limited by the input network filter, because TPA's can indeed go as low as 20hz

[@yahnsolo]

@@ATSNorthernMI if you have hiss and that "data noise" thing, it is probably related to decoupling and grounding, on the pcb side. Also, if there is more than one TPA chip on the same system, it's highly recomended to sync their PWM (pin16, SYNC pin)

[@RobinsonDanieldosSantos]

Nosso valente amplificador brasileiro. Taramps figurando bem no mercado mundial.

[@JasonRayShute]

I brought something similar from wish. I was about twice the size and claimed to be 500w. It would be nice to have a tester to see what it really is. Its It's probably the same, but sold as a 500w because it has 500 in the name. Great video. Very informative.

[@Brock_Landers]

This really reminds me of my first stereo system ever. It was in my first car, a 1990 Ford Festiva with a Sony Xplod tape deck, a Blaupunkt 12" in a truck box, with a bass booster. It hit OK for not being powered well, but it didn't slam until I bought a Sony four channel amp with a sub channel and MB Quart split sets.

[@ReelFilmer1]

This perfect for adding bass to my motorcycle helmet audio system!

[@whitecompany18]

I've got those mini subs in an RC Vietnam Swifty boat and that amp looks perfect for what I need to boost the volume from the mobile phone I use for the mp3 files 👍cheers

[@jvsyoutube3298]

should make a tuned box for those little subs hehe, make em slap!

[@monunyabidness5949]

Put that inside a small boombox from the 80s/ 90s, upgrade the speakers appropriately, and suddenly that lil boombox is thumping like a JVC M90 or Conion C100 at full blast. I had a little Sony CFS210 when I was growing up and that would be *perfect* for surprising people if modded in such a way.

[@cfunkbooya]

The dayton audio boards are legit, i Built my daughter a homemade portable speaker out of an old cherry wood cigar box and put two 2.5 inch dayton audio speakers and a passive rad and that damn thing is loud.

[@m3rk201]

I have something like this being powered by a milwaukee m18 battery on tool cart. Sounds stunning.

[@MeTuLHeD]

Fun project idea. 10 of those mini subs in an enclosure!

[@kjjustinXD]

Modern headunit power with class D efficiency while being 2 Ohm stable? Sounds like a Easy sound upgrade for classic Car stereos. 2 of these would be perfect for my Factory Quadrasonic 8 Track Sound system.

[@Gold63Beast]

A lot of installers use these to supply more power to door speakers without the whole amp in the back. You can hide them within the door.

[@SteveSega]

Is this the future hobby? Build RC cars with micro systems that bump? *Will IASCA start a new class for them?*

[@thebotlobbydaily]

Pull up to the lane with it😂 hilarious

[@henriquecasonatto8881]

hey i'm henrique from brazil. the porpouse of this amp is for hook in those chinese heads with like 1 or 2 watts, so door speakers sound good.

[@ATSNorthernMI]

These would be good with passives. I built a tube out of 2" pvc pipe I had laying around, Peerless by Tymphany 2 1/2" long throw line array drivers, with 2 1/2" dayton passives. I bought a DSP based TP3116d2 amp board by dayton and programmed the DSP with enhanced bass response with volume compensation so the louder you turn it up, the less bass it puts out. You have to hear this thing to believe it. It can hit lows so low that you'd think there was a subwoofer attached. I can hear all of the subwoofer tests you have on here with 2 1/2" drivers. I don't think you can find the drivers anymore. They have double magnets on them and hold like 30 watts. They are louder than the JBL flip tubes and other blue tooth speakers you can find at a store and sound clearer with tweaking the DSP and don't need tweeters being so small. Crazy little subwoofers though.

[@robsorgdrager8477]

Most head units do this power but if your car is newer and has a stupid infotainment system then this works great because you can get two and wire it into the speaker wires and run better speakers without using , my favorite, audio control component or buying a 2,000 dollar stinger head unit that may or may not work with the lin system in some cars.

[@Carl_Jr]

I know that KZbin compresses the audio in the videos, but based on previous videos you've made that amplifier seems to break up the highs a little bit and mid bass is really strong. Other than that, who can complain about a solid 80 Watts for $35?

[@GoldSrc_]

Seeing something like this just 20 years ago would have blown my mind and I would have called BS on it lol. Impressive how much more efficient class D amps are.

[@gu1m1ch3l1n]

In Brazil, they use a small amplifiers to make handmade Bluetooth speaker boxes.

[@vincentrusso4332]

Be a great headphone amp powered by any cordless tool brand battery in a backpack or fanny pack. Solder up the ¼" or 3.5mm jacks and you're golden. Great test D.

[@aaronatwood9298]

This definitely is meant for a Tri-amp system powering tweeters. What happenes if you feed it 40hz? Is it input filtered so nothing happens or does it chooch?

[@juniorsilvabroadcast]

Taramps is a brand from Brazil. My country. Here the car audio culture is something very very big. Lots of good quality equipment. And they are references worldwide

[@tkienzle22]

I usually watch these on my home theater system so I can see what they sound like when they. This one I watched on my phone. I felt it was fitting.

[@vforce1988]

at the 7:30 mark dont u mean 5 caps? unless the 5th is for something els?

[@chester82gtstang]

This would be sick for RC Modelers! 4S batteries would be a touch over 16 volts would love to see some RC cars with walls in them!

[@MOBAudioUSA]

I actually started my company MOB Audio just to serve the RC hobby.

[@chester82gtstang]

Link!?

[@Bassotronics]

Great for tweeters. 🤷🏻‍♂️ Great for model trains and bicycles.

[@rickyt310]

I bet a couple of these would do good in my stock chevy sonic. They've gotta push more power than my oem head unit.

[@jdlech]

Do you realize that this little thing puts out about as much as many 1000W. J.C.Whitney specials back in the day? And probably twice as efficient too. Just thought I might mention that. Not saying I'd rush out to buy it. Just that we've come a long, long way.

[@terracar2003]

Cool amp although I do wish it had Bluetooth, anyways i think i know the perfect use for these, that being a boombox, i have one that allegedly runs at 50W and i would love to bump it up with one (or maybe two) of these suckers, its a pretty small boombox (store bought) so size matters more, simple wiring + easy power = more fun listening and less time building, now to find some better speakers for it

[@ShlongOmatic]

I wonder how it would do on a 20v drill battery. Looks like the chips and caps would take it 🤔

[@HarmsWay500]

Those mini subs are awesome! I wanna hear them in a box!

[@HighVybeTribe]

All kinds of cool projects especially the custom RC cars with a banging system

[@gumpi5]

Maybe it's good improvement for old car cassette radios. They usually have 4x10 or 4x15 watts max.! But a thing I don't figured out a 100% is the following: When car radio have 4x 20 watts so can every speaker use up to 20 watt - in total (math: 4x20=80) 80 watts or are the 20 watts the "common shared maximum"? So the chip is outputting a 20 watts maximum and one speaker on one terminal could use up to 20 watts when the ohms are low enough or all 4 connected speakers can use up to 20 watts in total (so the effective power to one speaker would drop to 5 watts)?

[@therandomized2821]

dude best commit right here put it in a rc truck pure conteint right there

[@hatsunemiku838]

Can it be bridged to mono? And can it take 24v in? Awesome video!

[@dre04mach]

The purpose of this is easy, side by sides and motorcycles. I have an MTX "stereo" that fits in a rocker switch spot, this and a couple of 2ohm 5.25 speaker pods would be a good enough stereo for it...

[@johnperalta9415]

The main purpose of that i think is to fix headunits with bad audio amps. You could just wire that instead of replacing the whole radio. Good when you're doing a restoration and have a busted headunit. Also, it can be used in motorcycles and tricycles here in the Philippines. Its tiny and easy to hide. Makes it harder for thieves to find😅 lol

[@aaron71]

haha love it! I used a little 1" sub from an old Dell laptop with a diy bluetooth amp board and put it in a 1:18 scale Supra that had a fake audio setup in the back. Coolest bluetooth speaker ever! 😄

[@MAGGOT_VOMIT]

If you mounted the tiny subs in a Pringles can facing each other, would they cancel each other out?

[@hbeezey]

There are a lot of mini amps like that, although this one looks pretty decent there are better ones for cheaper, with volume controls, eq, and bluetooth. You can use 18650 batteries or even an adapter for a power tool battery like dewalt etc for a portable bluetooth setup.

[@Bubu567]

Possible use case would be to convert a passive bookshelf into an active desktop speaker. It's form factor seems ideal for that.

[@MrSmith-qu4nx]

That would be perfect to wake up a bluetooth speaker with a buck converter power supply addition. Thanks for sharing this little gem. ✌️✌️💯💯

[@nothanksgoogle5879]

This would be perfect for diy people or an electronics learning kit IF they got rid of the speaker level signal inputs and replaced it with a BT receiver and use a 9v system or a lithium battery compatible power input. I have a couple BT speakers that were damaged and I gutted them for spare parts or future projects, they're just collecting dust at this point... I know there are boards and converters you can put together or buy already. This is the only application I can think of for this product. They were onto something, but missed the audience that these would sell to by using the signal and power inputs that they went with IMO.

[@Choralone422]

There are tons of amp boards on places like parts express, ebay and so on with battery operation, BT and plenty of power. I built a PE Boom Box kit with my son last winter. It was fun and easy to put together and gets really loud with pretty good quality. This Taramps unit seems best suited for use on a motorcycle or similar vehicle.

[@RyanBassForLife]

Nice it would make a good amp for a portable stereo with speakers you can put in your pockets.

[@dyslectische]

We use in the 2000 and up small amps like that for mopeds and some speakers.beuld in a hardtop top koffer on the back . Speakers are shelf one. Easy to make and use

[@TheDutchman1980]

I vote that a little sub box be built for the mini subs lol, that would be awesome 😅

[@1sonyzz]

class D switching amplifiers are very efficient and used in most of new devices from phones and smartwatches to bluetooth speakers, the 200w rms amplifier in my AIWA Exos 9 bluetooth speaker from 2015 contains two class D chips the size of a dime without any heatsinks on them - each having 100w rms when bridged or 50w rms in stereo mode, one of the class D chips is used to drive each channel 3'' mid's and 1'' high's while second class D chip is driving dual coil 6.5'' subwoofer in a 7kilo boombox sized package on a battery power for 6 hours max volume and 10 hours with high capacity battery, I'm sure JBL came out with something better these days since Aiwa is from 2015

[@anchorbubba]

these are absurdly practical for seeming like a novelty product

[@joshuasilva7189]

I have one of those those AMPs lol. I got one to mess around with. It actually powered an 8" sub and also an older 200 watt 10" sub perfectly fine. But the low pass filter was at like 50hz or something like that. It'll power small speakers well :D

[@ghumphrey85]

I’ve got this amp in my garage on a skar 8” wired to 1ohm and it actually bumps harder than expected.

[@ChristopherGraham13]

I have a bunch of these little speakers and some tiny 3W amps and some Bluetooth audio receivers. I'm not an audiophile but I'm trying to figure out how to make a small enclosure for portable speakers. Something fun clearly not amazing but so it at least gets usable pocket sound. All the enclosure design stuff is for car subwoofers I assume the idea is the same but I would love to see how it works for these little booger speakers.

[@atticchopshop8180]

[@CommanderBeefDev]

this will blow your mind, i took a 20 dollar bluetooth speaker and put the output from it to a giant ass floor speaker and it ranit well and had bass, that was ten watts and ran off its own battery lmao, now make a box and put a regular 12 inch sub in it and use this massive 45 watt and i bet you need to turn it down, i couldnt keep the volume maxed at ten watts on my contraption without annoying other people

[@msunmshop5449]

Big D, I understand it would be just another thing for you to do, but would you be able to calculate the Db gain or Db loss when showing the output power of the amps? Some of us don’t understand what is negligible when comparing actual power vs rated power. Thanks as always for what you do!

[@JasonWW2000]

It's very simple. Plus or minus about 10% is pretty normal for all amps. It's negligible. Doubling the power is about 3dB. So a 100w amp that does 90w is about 0.6db down. It's the big deviations that are abnormal. A 100w amp that only does 60w is down 40%. That's about 2.4dB.

[@Wattitdo]

These would save so much time to just toss inside door panels really quickly😂. Real talk tho looking at the progression of car audio tech I can't wait til 2050 and be able to fit a jp77 in each door panel and a jp83000 on a single 12 with 4000% efficiency 🤙🔥

I want to see you test it at one ohm. For the last couple years I've been buying similar $30 & $40 mini amps on Amazon. Same situation they claim to be 100 w 2 channel but my ear says 20 watts. Yes peaking input Voltage does sound better and clearer. I have one 3 channel micro amplifier that powers a nice set of Polk Audio bookshelf speakers. The third channel the sub-channel makes it bump I'm impressed with it. I'm thinking somebody is JBL and other small mini expensive Bluetooth amplifiers basically have the same circuitry but they have a micro fourth and sixth order subwoofer arrangement given that that Dynamic boom with you here. I'm a hardcore hobbyist and I think I'm going to try to replicate something like that on my own out of wood or maybe 3D printed.
