this makes me feel a lot better about my purchase, I was worried about the sound quality. Not much technical testing out there for these android headunits. Can't thank you enough!

i wont lie, this some higher grade analysis bro, mind=blown!!!

Man, I'm LOVING these new videos! Please keep all this content coming Sam!

So funny I was JUST complaining about not being able to find any legitimate Bench test data on this unit and bam you posted it immediately before I get online to look for it lmao. Excellent detail, thanks man!

Appreciate the detailed head unit breakdown! I wish everyone went that deep with the nerdy details. Unit faired better than I expected it would.

Wow - this it's mind blowing how knowledgeable you are. Thanks so much for making these videos.

This is really usefull to me as i want to turn up my amp gains to lowest as increasing the amplifier gain induces slight noise in system and also increase turn on thump, good work mate , thanks to your work

I love the scientific approach of this video. The A/B comparison was really cool. I also thought thered be some coloring from the headunit as I remember some old sony headunits had pretty bad coloring in the highs

Very nice Sam. Most people dont realize that they dont get the power thats advertised on cheaper equipment. Then you have to take Impedance rise and frequency tuning and response.

Thanks for making the video and for your unbiased analysis. I got one of these Atoto A6PF's as a cheap and cheerful unit for our daily beater, and to see if these Android head units are anything more than just a gimmick. Frankly, I was expecting a less than stellar sound quality with interference galore, so I am honestly quite surprised by the clean output of the unit. Was also expecting those high-level output adapters to absolutely butcher the signal, but no. Now I'm kind of regretting the fact that I didn't look into these earlier.

great to see it all explained on the scope!

I really enjoyed this VIDEO!!!!:-D great job man,& HAPPY HOLIDAYS:-)

Please do more head unit reviews, this is amazing

Learnt alot. Cheers Merry Christmas

How did you known that i was looking at this? 🤔 Love your videos ❤️❤️

This is the way all head unit reviews should be done. What are the chances we can get you to do the same on the maxpeedingrods brand unit? Diy Car audio guy reviewed the unit and it seemed to be a strong competitor among these android units. I would be interested to see the variation, if any, amongst them or if they are all similar in build and circuitry. Great video, I'm a subscriber.

Quality review , product seems legit.

finally a really good analysis. thank you. Some reviewers didnt even talk about the sound at all. i mean wtf

7:41 20 years ago i remember having an Alpine HU (CDA-7873) with the "60w x 4" V-Drive amplifier that bumped the voltage up to 17v internally IIRC, pushed the MB Quart Discus 5x7's i had on it quite well

DEH 8500 BT+, brilliant old school head unit,loads of in and out, sweet sounds

I have a pioneer head unit a 4400 NEX Last year, it was stuck in a boot loop. I was so angry didn't last more 3 Years I was thinking... So I kept looking online and found out a fix. It turns out the internal SD card failed. Turns out they use very low quality SD cards so I had to find a way to put that program onto an SD card ... Luckily, on a KZfaq video and a online forum, I found a program and the software to put onto the card using a laptop.. It was pretty involved, but I dismantle the unit got the card out with no damage replaced the card .. It booted right up like it was new better than new because the SD card I used has a higher read speed It's only a second or two faster which isn't much... But I used a pretty high-quality SD card, and I made a extra copy just in case I need to do it again in the future.. works perfectly. I even recorded me dismantling it and replacing the card but I never put it on my channel. I still need to edit the video. That was over a year ago... but yeah, another thing that annoyed me about this unit is the touchscreen dust particles behind the glass... So a few months ago, I decided to take the detachable face apart carefully.. I dismantled the screen And just cleaned away the dust particles it was pretty easy actually now it's spotless again.. But yeah, most of the battle is taking that 1st step with repair things. Being scared to mess things up as long as you're careful, you should have no problems.. Just to send in the head unit they wanted a few hundred dollars to just look at it.. for the card fix .. there's also a guy on KZfaq that made a video that pointed me in the right direction.. Other pioneer units have The same problem Poor quality SD cards in the unit. Hopefully they fix it. But I'm sure they didnt . They want the repairs to come in.. are you doing any Christmas repair special this year? It was fun last time

Superb analysis. Learned a lot in a methodical manner. Just ordered blaupunkt key largo 9 inch android player which does have rca outs. Hope it can serve as a good player.

Back in the 90s a lot of pioneer head units had a feature that allowed you to lpf the rear channels and you could bridge the rear channels of the head unit too I believe. There was a guy in my hometown that had 4 6x9s n the rear deck of some kind of like 90s Oldsmobile with one of those pioneer decks and it put out impressive bass. I believe they were 4 like oem GM speakers.

Great video sir keep up the good work 👍 👍

Thanks a lot for this detailed analysis of the Atoto head unit. The first Atoto I had was the 10” A6 that completely crapped the bed on me after like 6 months ownership. Atoto refused to replace it with an identical unit, only offering a lower tier head unit than the one I had purchased. Instead they forced me to pay the difference, so I said screw it avx upgraded to the 10” s8 from Atoto. About 6 months into owning, the stupid thing started factory resetting itself completely out of the blue. It’s extreme frustrating to have yk download every app, sign into everythhvg again, tube the dsp and stereo, just to have it factory reset two weeks later. Atoto has been ZERO help with this even though it was within warranty. They told me I had to send them a video if it happening…..HOW TF AM I SUPPOSED TO TAKE A VIDEO OF THE HEAD UNIT RANDOMLY FACTORY RESETTING ITSELF?!! I would have to record hours upon hours hoping to catch it in the act. I e had 2 Atoto these units, both have shit the bed within 6 months of being brand new. I will never buy from them again after failing to stand by their product and they’re warranty.

good video mate cheers

This cheap head unit is perfect for my convertible since acoustics go out the window anyway.

~14 minutes in, I don't see that you listed the deviances in the resistive values that were used. Such deviances could also be because of minor differences in the 4 ohm load. 4ohm resistors are rarely very precise. With that said, as an electrical engineer, I loved seeing this style of "not-a-review" analysis, keep it up! Very well made!

Thanks 😊 I just picked up an A7... good 👍 enuff

Hey Sam, I'm surprised you don't have an rta to see the electrical response of the signal. Its great for looking at crossover response. If you have an xlr microphone going into a xlr AD converter and REW you can swap the mic for an rca adapter and run the signal in. You can then see the frequency response. You can also see the frequency response of passive crossovers as well.

This was awesome thank you so much for this and all of your videos, I tremendously love your channel. I know you probably don't have 1500 bucks just laying around, but would you considering doing this exact video for the Kenwood flagship 1057? I know this is a long shot, but if you do thank you in advance and keep it up brother!

Would be interesting to see the same test ran. On a joying or teyes head unit.

Love the video! Is that the music from Zelda in your comparisons?

About a year ago, I tried using a fake topping d10 ( Aimpire AD10) with my double din android head unit. I used UAPP (USB audio player pro). Sadly UAPP would never detect the Aimpire AD10. The built in DAC in my android head unit was horrible when using the RCA outputs. I switch to a line converter which didn't help at all. I got rid of it. Im now using and EQ to switch between the factory radio and a 5th gen IPOD playing lossless using rockbox. The 5th gen Ipod DAC sounds great.

Sam, I have an Atoto A6PF in my Kia Optima, driving some Kicker 6.5 inch speakers in the doors driven by the head unit. I've been very pleased with the audio quality. Do you have a suggestion of a budget 4 channel amp for this setup? The Kickers can handle up to 85w RMS. and my budget is quite limited, not interested in a sub. Thanks for all you do for audio, and thanks for the collabs with Big D Wiz!

id like to see you full test a top tier head unit next to this ali express one

I am an Engineer working in this field, and would like to say I think you did a really good job in testing this with what you had available. Obviously most users of this system will not be testing it like you have done, but it is interesting to see where the system fell down. One thing, if your scope allowed, you could measure the time delays and compare that to the input on the screen. Either way good job!

Dyno headunits needs to be new trend

100% In agreement about the complexity of modern head units. The oem hu's lag behind good Android phones in high quality Bluetooth audio streaming and only the most expensive after market hu's match Android phones. I have bypassed the hu in my own installation. I stream APTXHD Bluetooth audio from my Pixel to a FIIO BTR5 Bluetooth receiver that is plugged in to an Audiocontrol Three2 in dash equalizer. The Three2 provides all the basic audio controls and the BTR5 has an 11 band equalizer as well as handling phone calls. A Tunai Button Bluetooth controller provides steering wheel controls for all the basic functions on the phone.

It is the best head unit I ever had. 🙂👍

I wished you where fixing amps in the 90's.. i had a Rockford Power 300 Mosfet amp which did my whole system until it blew a channel and nobody could fix it, never heard the sheer power from such a small little amp in those days.

Nice one brava

This is the truth

Love the thorough approach ! as an AV engineer with a degree in Sound production i am very pleased with that process. Only i would have liked to know what is the Quality the bluetooth transmission and streaming over carplay... especially bluetooth ... even my pioneer unit dmh-1770-nex is REALLY disapionting over bluetooth. thats one of the reason i was looking for a change. i had a 30$ gadget from amazon that streamed better bluetooth that the pioneer headunit... thanks man !

Very interesting

GREAT analysis! Question: Atoto has various versions of the A6. Was the one you tested compatible with 2 ohm speakers, and if so, could you run a test to see how that would do? Thanks!

15 watts is standard for 90% of modern head units. their internal amplifier is rated at 25 watts peak at 18v. so the output is pretty standard.

I agree with you about having physical controls in a car. I bought the Atoto S8 which doesn't have any physical buttons at all and that is really a downside for me. Anyone considering one of these touch screen head units should take that into consideration.

So the amp of the unit is enough or i have to use the line converter to use the amp of my car? i buy this atoto yesterday! thanks bro!

I tried out a deck with a real built in amp. Had to run dedicated power and ground to it It will cut out without them but I quite like it its greatly simplified my setup only need a sub amp now and the built in dsp and time alignment is good enough that I no longer need any sort of processor. No distortion until volume is at 100% and its plenty loud well before that point anyways.

How does it compare to a good old pioneer headunit ✨✨

I get very little volume from the internal amp until it’s about half volume and at that point the ear fatigue the one I have causes is unbearable. It was to the point I thought one of the tweeters was burnt out! I’m surprised to see this perform like it did. China quality?

Depending on your choice of DSP, you can have all of these options this Android unit is offering on your phone, tablet, and computer, without replacing your head unit. I always tell people, your head unit is your source and the heart of your audio. If you’re going to get a head unit, get a well known manufactured head unit with history of building quality units. Why buy a piece of crap, or go cheap, or settle? Save your money, buy a phenomenal head unit, and go from there. Not only will it save you from unknown disappointment, but it will save you from spending unnecessary money to get what you want. You have to know your system and what you want.

krasser Typ 😳

I was complaining just today on how I can't find a deep analysis of Atoto head units on the net and voilà my favourite channel posted it! I'm looking for a 2 din to buy for xmas; I have sound proofed doors, Hertz cento speakers and sub (sealed enclosure) and Hertz amplifiers. I'm stuck deciding between Atoto S8 Premium (built in rca outputs) or Kenwood dmx8020dabs or Pioneer sph-da360dab I know that probably japanese head units have better hardware and sound output, I had a sony mex-xb100bt and it was really nice, but the atoto is cheaper and offers better multimedia beacuse of the android os, but will it bottleneck my "quite expensive" sound system?

Very interesting. I love seeing the objective data we never had for decades. Confirms that even a lower end android has impressive dsp capability and signal quality. The DSP labeling is just a quirk of your unit. Consider testing a better unit like the Teyes CC3 I just installed. It has more sensible labeelling of controls and full RCA outputs as do many others. I agree they can be a distraction. I think this diminishes with time. So far the thing I like least is no volume knob. I does do 2 finger swipe for volume which may be fine after more time to adjust old habits. The ability to customize all its functions to individual tastes is impressive. I can even monitor OBD data. While there are some features I don’t yet fully understand I’m very impressed with the dsp benefits.

Wow over my head a bit lol. I just notice that when i use apps to control the volume like Power amp and change back to the radio, it tries to blow my speakers through the doors.

Mostly of car radio can't produce a deep bass , Hpf to 60hz like you say will reduce that cheap noise in car doors. I m remember some old decent pioneer, alpine,sony, jvs, Kenwood, made in Japan ,will produce only 7 watts x4 , nice sound .

Have you seen the 400v 100.000w car-amplifier that belongs to Loudfiat here on yt? How does it work? Any thoughts?

Curious how much can you turn up the gain on these Atoto line level converters before distortion in introduced? Kicker ones gets to 7.4v before distortion is introduced.

I was searching through your old videos about setting gains and as simple as it sounds, you really do not have a video that I can find on the process of setting them. You had a video about matching multiple amps and then another about setting gain with/without subs connected. Would be nice to just have a short video or topic about setting gains.

What's the power output chips on the stereo?. My Sony MEX-XB100BT have class D outputs and I'm sure is using a High Power Current DC to DC Step-up voltage inverter to elevate the feed voltage from 14 to above 24V. How you test that?

I suppose the x-over on that H.U. having lo-pass filtering would allow you to bandpass a pair of channels if you needed to, like if you only had mid bass woofers in the rear.

I have a pretty cheap double din android head unit. I've debated on installing it but just for testing purposes I hooked it up to a set of 15" sharp cabinets from the 90s and it puts some decent power to them before clipping. It's surprising to see you wouldn't be able to hear this head unit over road noises from a section of concrete highway 🤣

What are the correct settings so that audio accompanies navigation? On my A6PF unit I only succeed in one out of about 20 tries. When I bring up the microphone search symbol when I am on Google maps sometimes it chimes before entering a command and at other times it does not. When I say _navigate to 1234 Main Street_ the route is always marked with a thick blue line. That feature always works. It is a distraction to glance at the screen. What I really want is audio that provides directions. The speaker symbol that comes up with route search is not in the mute position. Both GPS and WIFI are connected. Somewhere I must be overlooking a setting and the directions that accompany the unit are of no help.

Wow... didn't understand one single bit of the video. :) It's so technical, for me it is like a hieroglyphics.

Hey same what volume did this clip at. Would help me with gain balance.

Oh yes, i hoped you were able to use USB DAC's on Android headunits, i was thinking about ever doing a SQ build with pro amps or perhaps door speakers made out of a pair of old studio monitors with their OG amp on an inverter, a balanced in/out dsp and an old M-Audio FastTrack Pro i've still got around, that's fucking awesome as you can probably buy the cheapest and worst Chinese Android headunit and get great quality audio now i wonder if you can do multiple USB DAC's for more channels/copies of the L+R or will it only output to one? USB DAC?

thanks for the info on Android head units I bought one says it's HD radio 🤔

How do you not have a million subs cant beat you reviews

Sony makes a high power head unit. Big D even put it on the dyno, did better than rated. (50w x4 rms)

btw. ive tried an alternative cable that has front l,r Output so the hu has this but is limited through the cable that comes in the pack. i wounder if there is a right channel for the sub also hidden in the socket.

Some Sony head unit come with 55rms × 4 watts!!

just put this in my car, but for some reason the gain adjustment knob for my amp isnt responding and has very low bass out put still tinkering with the settings

Thanks! Have can bus?

Would this radio go good along with 2 deaf bounce neos ?

What was the second song you turned on?

I wonder if you can unlock the USB volume control by getting into the Android Developer Options. I also wonder if you can use a Dayton/Ground Zero 4x8 DSP as a USB DAC. 🤣

The android head units are alright, but you definitely need to run a dsp to help clean up the signal and add a slight boost to the subwoofer channel

I think it's respectable they sent you one, or perhaps they didn't know how poor these units are themselves. However, great video and loving the analysis!

So can you use this Atoto A6 head unit to power an external amplifier and "bypass" the build in one? Does not seem to be any pre amp output.......

@barevids i recently installed a really cheap Android HU (thanks to a friend) and i noticed that when i play with volume above 25-30, i get a lot of higher frequencies, voice, etc... but anywhere below that, everything becomes so muffled it's horrible. Sound is really not that great going straight to the speakers (no amp). Did you notice anything like that during your tests. Or is mine just wayy to cheap?

I will stick with my alpines they always been my favorite.

What was the most powerfull head unit ever made?

The wires on the desk......... Now thats a rats nest to be proud of! lol

hello, Itnx for making this video. But I can't find a answer on my question. I wander this, Is it possible to install a working Smartlife on this kind of Carradio? I would like to use this as sort of a home kiosk? TIA... Reply

barevids i agree i like sliders and knobs f all that hi tek crap

Good day can u do a review of the mmats 4000.05 please if u can

Does anyone know if the Atoto Equalizer can be installed on another Android headunit? I'm really liking the crossover HPF in the eq, but do not have that option on my Kroak headunit.

I run a single din kenwood, works best for my bass system.

Hey, can you please do a video on how to bypass filter section on amp for improved sq

Someone should send a modern head unit to ASR

At what volume level does it clip?

Has anyone installed this in a Hyundai i10 2010? If so, what mounting kit did you use? Thanks

Should have done the Atoto S8 pro

People have different levels of attention spans. I fully agree that majority of people have a shorter attention span over all. Now, when the climate control is needing to be accessed by touch screens, as more things are needing to be accessed that way, the more it takes away from the drive. But as far as navigation, I find it helpful, as long as it is mounted high enough that when I scan to my rear view mirror I can, roughly see the layout of the road I am driving towards. That means that if I am not familiar with the road I am on, it will show me where I need to slow down dramatically, because of sharp turns, and maybe a wider sweeper, so I can keep my speed to where it feels comfortable, and I might pull my speed down smoothly, before I get to the sweeper, and then if I did need to reduce my speed, then that prevents me from shifting my weight to the front thus removing weight on my rear tires. That means that I would then have a smooth pull out from the corner. What if I am just driving in creeper mode, then I will not be shocked if a vehicle pops into my direction that I am heading towards, or instead of slowing to a creep in a sweeper, pissing people behind me, and vice verses, keeping a little too much speed into a sharper corner.

Would this be could with a good amp

I have the 8 version of this head unit and it's much better!

Got a fast question for you I have a M.A. audio HK4000D hard kore competition amplifier trying to figure out the output channel has irfp064N for power supply possibly like irfp9640 and irfp240 would like some information on it I've searched everywhere including old school forums thanks thebestyet218

Only bad thing about the atoto is it's only 2v output
