Where to find O-scope:
Search amazon/ebay/etc for O-scope. you will see them for sale. Fine one that is assembled and has included power supply. The units come in white and also black. They are branded by many different companies but all pretty much function the same.

I got one of these. Helped me quite a bit. I'm new to car audio. I've learned a lot in the last 6 months. I now have 2 Skar evl 12s with a skv2 1500.1 ( it's enough, don't want to upgrade alternator yet), jvc touch screen head unit with a dual AGM battery setup with a stinger isolator. It's in an 09 maxima. Did the big 3 as well. Every wire is 1 AWG ofc. I'm proud of my install since I did it all by myself. Had no idea what I was doing. Through trial n error and many upgrades I ended up with what I wrote above. Also I was struggling to tune untill I saw your video. Thanks man.
Thanks for the feedback. Awesome!
just got my o-scope, can't wait to tune my salt 3k. Hopefully I have enough power for that amplifier. I have a 240 amp alternator, and (1)xs3400 battery. Pushing (2) skar vxf 12's @ 1 ohm. Currently have them on a jp23, but they seem underpowered.
Sounds legit
That's man no one starts as a expert congrats ... On ya install
It’s been two years how’s the car audio been going ?
Iam Computer Engineering student and love to mess with this stuff on my spare time. That O-scope should be good enough for most of us. There is definitely other small parameters but honestly, the difference is minimal if you're looking just to set gains.
Hey bro, from one car audio enthusiast to another, thanks for your video! There was alot of useful information :)
Keep up the good work!
Thanks!
Not a problem 😃👌
Let's Have NLA (Next Level Audio) printed on the scopes and sold like SMD did except they will be affordable for us average Joe's..... 🙏
Good idea! 😂
Great idea!! I would buy one!
If I purchased one of the SMD, I'd probably put a decal over it. Dude is a 🤡!
😆
Saved my life, wallet and gear! I say life because my wife would kill me if I had to replace my gear again! Great vid bro! your on that NLS!
I have this exact oscilloscope and guess what... it runs on 9v. Which means yes - you can hook up a grocery store disposable 9v battery to it and have a truly handheld accurate oscilloscope! Cannot confirm if this affects the accuraccy or anything, but mine's been running great for ages with a 9v disposable battery connector soldered to the + and - of the power cable input. Just double-sided tape'd a 9v battery holder to the back and voila. No idea why they didn't design it like this to begin with, seems like a no-brainer to me.
Been doing the same thing. Bought a 9v adapter and a rubber band holds the 9v to the back of the device. Still on the same battery even a year later.
I have the same little cheap O-scope. I had to build it myself, it was a kit. And it came with a 9V battery connector-wire with it, to use it exactly as you describe. So yes you did great, it's meant to be used by 9V battery. Power supply must be very precise between 8-10V so a 9V battery is perfect. I just don't understand why it has to be external instead of the manufacturer designed the 9V battery internal in the housing :) would be even easier to use and maintain.
Thank you for this video. I bought that O scope because of you.
By holding down your V/DIV button should make the hole line visible not only the top part ( the same as the big Oscope one pretty much )
just seeing you explain the other channels test tone, you're awesome! thank you!
Im going to order this this coming payday thanks man.....i like that how you are not arrogant you're just humble
Thanks man
@@NextLevelCarAudio no... Man... Thank you
I had to buy one 🔥🔥🔥 life saver next level audio ✌️
Hell yeah
I love the little oscope i just got one last week and tuned my amps... something to listen to..
100x4 and a 1200x1
Hey brother I have a cool video idea!!! So you’ll set the gains by ear and then see how accurate it is by reading the sine wave with that oscilloscope!! 👍🏽👍🏽👍🏽
I’ve actually Tried that. But have not video recorded it. Maybe in a future video
Please do a video on different db Metters for us budget builders
Thanks for doing that test I would definitely buy one of those cheap ones not worth it for me to buy something expensive when I'm not a pro thanks again
I used this method to test my Kicker CXA400.1 "400 watt" amp and it made almost 700W before clipping.
Wow! That’s impressive
@@NextLevelCarAudio It was also useful for finding out my Pioneer DMH-W4660NEX head unit doesn't clip on the outputs until 39 out of 40 total volume and this was with the EQ set using a pink noise generator and the Spectroid app. So I knew I wasn't sending clipping to the amp, and then was able to find the clean limit of the amp. So easy, so cheap, don't need several hundred dollars of equipment to do it right.
You got that right. That’s awesome man 💯
@@jamesg8246 The _what_ app? Seems I can't find it...
@@RAW_Reality Spectroid
Very good video ! Thank you.
😂😂😂 SPOT ON!!! HATERS ALWAYS HATE WITH NO RESEARCH DONE😂😂 NICE VIDEO! BUYING ONE TODAY FOR $37
Hell yeah man
In fact your right some people just want a good amount of power and crisp and clear sound its not always about max max max max if you have plenty keep it lower more headroom less loss of dynamic range and less harder on your amplifiers........nice vid bro
Thanks!
@@NextLevelCarAudio with a 40 hz test tone and listening at a sub its very very easy to hear the sine wave starting to clip true in the higher freq its a bit more difficult
What do think about buying amplifiers that are too powerful for what they need to power therefore using lower gain underpowering the pre-in and losing dynamic range ?? Myth or it needs to be really really low to happen?❤
I think having a certain amount of headroom is important to not over work your amp. To what extent tho I’m honestly not sure at when or if at any there are any deteriorating factors. Good question tho.
@@NextLevelCarAudio thanks bro your content is awesome 😎 im trying that o scope today ❤️a big hug man
might just go ahead and buy this one!!! hope its as accurate as you say it is!
I have to subscribe for sure. Keep it up bro 💪
Thanks for the support!
Should you also do the test with your normal settings after you do it with flat settings on your deck? Or does it not matter?
I always do it with my head unit set how I will actually listen to my music
Hey brother I have stereo kendwod Exelon 907S seems no clipping at max volume that weird no. Is 5 volts what do you think
Some head units (good ones, not the cheapos) don’t clip at max volume.
Just ordered one ! The Luimy one i have is garbage..resolution is so bad i cant see the signal clip until its almost square
Great content, people its not a volume controll , good videos, next level 👌
Is it a concern that the handheld o scope doesn't have the range to see both sides of the sine wave? Mine is also this way and didn't know if you could clip on one side of the sine wave before the other?
I got mine for 25$ now if my box is 43 hz is that the tone i use. Thanks for sharing
When setting gain on four channel amp just connect the probe to the speaker output as well like for subs have my sub amp gain how I want with the 40 dollar scilscope you mention from Amazon but now I want to set my 4 channel amp
Yep, that’s it!
Hi, need advice. I bought the same O scope from amazon. I have followed your videos to the letter yet i cannot get my O scope to display the clipping wave like you have here. I have my setting set as you do here but i only get very tiny display. Nothing like yours. What am I doing wrong? How can i see the same as you have here? I tested my radio first. Found the distortion is just pas half way up volume. Then I started adjust my amplifier gain. It sounds good but I feel lost. Can you do a video to better show how to manipulate this device better? Thank you. Im installing 2 two channel amps on a 2019 BMW K1600 Grand America using the output of the stock sterio to the input of the amps. It has a line level filter on both designed for this. Front and rear speakers as well.
Can you do a video showing and explaining how to calibrate oscope please?!?! Mine came with crappy instructions that actually had 2 different contradicting explanatioins?!?! I got aggravated with it and tossed it in a catch all drawer. I have a system in my car and I've been wanting to use my oscope. My scope doesn't do anything but show error message and very irradiate graph...
Why does my wave start in the middle not rise from the bottom like yours?
In have no idea... never had that issue. Sorry man :/
@@NextLevelCarAudio I'm having this exact same issue... mine reads from the middle showing the top and bottom of the sine wave. I've watched this and your other video multiple times trying to see if I was setting something wrong. 20v does not give me a large enough window to see the full sine wave with it reading from the middle. (I have your exact "cheap" O-Scope). If someone finds the answer to this issue please let me know!
You have to go to the 20v symbol and click the yellow box off of it then turn the adjust knob till it moves from the middle to the bottom
Cool, i have order same or simelar on ebay. will be cool to try out, have a monoblock i need to figure out how it clip up to the clip light on the bass level control in my car audio.
Do u have a video on how to use this tool?👀👀i just order one
I need help with a fancier o scope.. can ya do a video with the fnirsi 1013d o scope
Last part you said alot.great job look foward to more vids
Thanks!
I bought the oscilloscope and I cannot get it to work properly at all the sign waves are not show up bigger what am I doing wrong
Excellent vid! Can you measure the clipping signal without the speaker connected do the amp? Or do you need to have them with you connected all the time?
Can do either connected or disconnected. :)
I have a oscope like this but when i tune my amps it don’t square off when clipping the wave is always fuzzy
great "how to" vid, thanx man!
You bet!
Can you do a video on subsonic filter and also when tuning do I set the subsonic filter first and then the gain or reverse
I kinda go over it here:
ua-cam.com/video/ChhbQfpV8wk/v-deo.html
Dial in all your filters first then set gain. Gain should be the last thing you touch.
Hey brother. I blew my amp using oscilloscope because the settings was not set correctly. I blew my sfb 8000.1 sundown audio. I cried then got my ass up and order down4sound and order one more. Then im waiting for my amp too arrive this Thursday. I have my back up amp and this time i set the settings correctly how your video show me. And it did not fried my amp because of your video haha
Dang man, that sucks. Sorry to hear that. But glad it is working out for you now!
@@NextLevelCarAudio yes it is brother. And i i got me two 15inch zv5 sundown audio subs. I have question. The box says 2000 rms. What the actually highest rms can the zv.5 put out on rms. They told me 4000 rms. But since you have 3 of them. You should know the answer.
My 3 are getting about 5k each (15,000 total) but I have very solid electrical. They can definitely handle 4K each. Just don’t send a clipped signal to them and your golden
@@NextLevelCarAudio Thanks brother!! Im glad there people like you that helps and comment back. Im going be using my order that i order SFB 8000.1 Sundown audio mono block. If my wiring are solid connected can the subs ruined my amp any kind of way of it hurting it.
The only way your gear will get ruined with your setup would be if you drop below 12v or you send clip signal to sub. So set gain properly and have good electrical. Done ✅
iknow u said just fade the speakers so the test tone want damage door speakers well my lci is taped into front speakers which gives signal for subs. so fading to rear will that effect setting gains
Well damn. I just spent $190 on a dd1.
Im tuning my factory head unit should i keep the oscope at 2v?
Great video man
Thanks!
Will amps clip at different frequency, if my head unit is at its max clean signal and I know ima be playing 30hz, would the lower tuning change where the amp clips at.... or is it clean at any frequency once it’s clean..?
Only if you are boosting certain frequencies.... for example if you are bass boosting say 60hz, but dial in using 40hz 0db tone, the. You will be over clipping when you hit 60hz. So need to be aware, yes.
Will it withstand/measure well when Vpeak is > 50V?
Thanks for this video! I want to set my gains for my amp however I'm not sure how to turn off the signal to my front speakers so I don't blow them up with a 40hz signal? It's a pioneer avh501ex...any ideas?
If they are crossed over then no issue. Or are they stock speakers running off head unit? If so, just adjust fader all the way to the rear. That will cut out the front almost completely
@@NextLevelCarAudio I am running after market 6.5s directly to head unit. Have my head unit crossovers at 100hz but will now attempt doing the fade option to see if this solves my issue. Thank you!
Awesome. Yes, that would work just fine
How to check crossover frequency
I have a 4 channel amp running 6x9 for rears and 6.5 components for doors.my question to you is should I set my hpf. Of full or lpf?confused
HPF around 100hz... you don’t want them playing below that. It will sound distorted, below 100hz you need a subwoofer
Thank you
@@NextLevelCarAudio gonna hammer you with a few questions here, if I set my 4 channel for my mids/highs at 100hz on hpf what should I set my sub at? LPF 100hz as well? Or 80hz? My mids and highs have a range between 60hz-22 Khz, is it ok to go lower than 100hz on them? Also you mentioned that we should setup all our EQ settings before setting gains? Can you explain that and what should I set the EQ min/max dial at on my amp that's above my freq dial and below my gain dial? Thanks for all your knowledge!
100 is just fine for sub LPF and mid HPF. You set EQ before gain because if not, you can introduce distortion by increasing the db on your EQ after gain is dialed in.
QUICK QUESTION ARE YOU ABLE TO TEST THE MAX VOLUME WITH THE OSCOPE OF THE HEAD UNIT BUT USING RCA OR DOES IT NEED TO BE OFF THE SPEAKER WIRE ?
rca are low voltage so wont get proper readings
@@NextLevelCarAudio ahh thank you!
Would this work on headunit RCA preout to see highest cleanest volume?
Yes
@@NextLevelCarAudio how would one set that up to see max clean volume from rca pre-out connections ?
RCA pre out or low level hardly ever clip even at Max volume. Just set as normal and put one probe on outer sleeve and one on inner.
So I'm setting my gains on my amplifier right now and it works great but where's the voltage Vmax vmin vpp and vrms which one do I use
I think I might have found it I think it's vpp
So next level do I use VPP yes or no?
Not sure man, I don’t recall and I won’t have my meter with me anytime soon. Away on business now. Sorry
It's cool I definitely figured it out thank you . anyways I just made sure I had a clean sine wave then used my DMM using the square root method to get close to the Watts that I needed to match my subwoofers RMS. then when I went back to the oscilloscope I seen the same voltage that was on my DMM on the vrms of the oscilloscope. So boom there it is. BTW thank you for showing me this oscilloscope I've been wanting to buy one forever but didn't know which one to buy... this was the best one ..easy to use and had the cleanest picture to look for clipping, easier to read than the Liumy..thats for sure...yeeeeeeew💪💪🤙🤙👍👍✌✌🔥🔥
Thx for the video 👌🫡
man I don't know what the hell wrong with mine I can't get it to come set at 40hz it's stuck at 1khz idk what to do it looks nothing like what's yours is doing it's all distorted looking and show no peaks of the sign waves
That sucks man. Yeah, not sure what the issue is…. Sorry :/
Still the happiest bass head ever
I seen your other video. You said to test mono for subs on 40hz to set the gain. Now would I use the same thing to set up four channel for speakers (6x9 and 3.5 tweeters)?
Absolutely, but 1000hz vs 40.
I got two of those cheap ones, I can't get it to show what yours shows as set up. Any chance you could do a set up on the oscope how you got to those settings on the screen?
I have an older video of me setting it up. Look for video called cheap o scope.
@@NextLevelCarAudio thank you 🙏
Ok here is a real good question on how do I set my amp gain with a multimeter I have two skar zvx 1ohm dual voice hooked up to a skar skv1500 x1 I have a 2006 caddy dts factory head unit plug and play pre amp hooked to the back of the radio gain turn all the way up on them ok I need 38.72 to read on my multimeter but the highest I’m getting is 10 and that full volume bass eq flat across the board and gain all the way up on amp to is there something I’m missing or doing wrong need help
I’ve never used the multimeter method. Sorry :/ i like I scopes so that you can actually see the wave
You can use this to train your ears too to listen to distortion
hell yeah!
There are differences between the subwoofer connected or disconnected?
Slight voltage differential, in some cases more apparent than others. In my case, with how my system is setup and the power I’m running, it did not matter if I had them connected or not, as the results were negligible.
So once I know the clipping point on my head unit and all settings done on head unit. and turn bass knob all the way up and I set my amplifier to before clipping. Should I set the amp right before clipping or back it down some more for safety????. I've blown my sundown x8v3 4 times already. I think because I set my Kenwood double din to volume 29. And sometimes I would go 30 31 32 33 34 and max 35. Maybe that killed my subs. Or the box wasn't built specifically for my sundown x8v3. . I did something wrong. I play nothing but deep bass music no words just bass . I used to play my system to loud too long. Not anymore I turn it up for a little bit then I turn it down for a while. Then every now and then I turn it up to let's say the volume 29 where it's safe. I'm slowly learning how to take it easy. I just wish I had a system i could just bang on for days. I just bought some sundown x10v3. Upgrade time. And I really don't want to blow those new subs. So I need all the advice I can get bro. I appreciate all your videos and helping me. Your videos are so helpful.
Yes. Set head unit volume to max unclipped point. Then set gain to max unclipped on amp. Then DO NOT turn volume knob past that point orb you will be clipping and kill your subs
@@NextLevelCarAudio alright. Thank you for the tips. I will follow the instructions.
Bro I body and I said it like yours but I can't get the signal wave lines to go like yours can you break it down for me or let me know what I could be doing wrong
What signal? Frequency?
I just bought the mini oscope. How do you test the deck RCA? I've hooked the clips up to the rcas played a 40hz tone but no wave is shown on the scope
You need to adjust the voltage on the scope. They are low level so sensitivity needs to be set higher to read it properly

I’d definitely go Mechman. They are rated very well even at idle speed. That with your big 3 and under hood AGM replacement I’d be shocked if you are still dimming. If you are, at that point it may be that Gains are too high.

You bet!
Like the fox hat do you ride dirt bikes

When setting the amp by ear what volume should the deck be at?
Max unclipped volume. If you don’t know what that is, then industry standard people use is 75% volume
@@NextLevelCarAudio and bass know at max right?
Yes, or max you will ever turn it. Then just don’t go past.
@@NextLevelCarAudio can you set it with music or it has to be with a 40 hertz tone?
Has to be a sine wave. So yes a tone
what is this powered with, USB?
Standard wall outlet.
Great videos!! Can you tell me how exactly you connected your bench top oscope; I got one used and it wont give me a signal? I'm thinking maybe I'm missing correct wires. Thanks.
The clip to negative speaker wire and probe to positive speaker wire. That’s it.
@@NextLevelCarAudio that's what I did. I wonder what I got wrong or if its faulty. I have a liumy and found absolutely no clipping on my deck , RCA or amps. I find that strange so I wanted to recheck. It's a kenwood excellent deck and monogram alpine for sub and 4 channel bridged to 2 channel for rear sets. Gains and volume are maxed and no clipping on liumy and I hear none by ear.
Wow.... that is strange. Did you try tweeter method? Cheap and easy.... I am releasing a video in a couple days going over it.
@@NextLevelCarAudio I'm not familiar with that method. I'll be anticipating your video. Love them, thanks.
Hey nextlevelcaraudio last night I heated up my sub and it started to smoke. I was doing some test to set my gain. But I shut it down immediately once I saw it. Should I be worried the sub seems to be fine.
Usually the smoke is just the glue keeping the coil wound that’s heating up and burning off. If you turn it off right away, you may be okay. But the integrity of the coil is probably weakened
I know to disconnect my subs when running a 40hz wave , but my front door speakers are connected to my HU. How do I keep the 40hz from running threw those. Do I need to pull HU out and disconnect them ?
You can always adjust fade setting on head unit all the way to the rear. That will pretty much eliminate all input going to your front speakers. Then you are set
my issue is factory radio my lci is tap into the front speakers because ford thats where u get voltage -ohm readid to tap in so can I still fade it rear to set gains
Hello I just received mine in the mail but it didn't come with a power cord what did you use for yours.
It should come with one! Either wall plug or 9v battery adapter. Your unit seems to be missing parts
Bought mine months ago, opened the box lastnight mine was missing the power cord also 😅... just ordered one off amazon like $8
Dang. That’s sucks
Thx sm 💪💪
Hey next level... can you read the voltage of how many volts are coming out of that amp on that scope? Let me know cuz I'm going to buy ASAP if it does
@ next level..How does that oscilloscope connect? I see it comes with a 9 volt cord but do I plug that straight into the wall and does that cord converted back to 9-volt I'm confused. Help.. because when I went on the site it says not to use with anything over 9 volt or it will fry it
Some have a 9v battery input, some have 120v ac wall outlet input. Depends on the model you buy
It does display voltage
@@NextLevelCarAudio I just ordered the etepon ...the same exact thing different name... but it comes with one of those plugs . I also ordered one of those little 9-volt battery adapters with a lithium battery rechargeable so I can take it outside or wherever without a cord. But if I wanted to use that cord it came with. do I just plug that straight into 120 volt wall socket that's what I was asking earlier. I don't want to fry it it says it's a 9 volt battery cord . does that power cord convert high-voltage into low-voltage(9v) is all I'm asking?.. I know I'm asking a lot but I'm just curious sorry
Yes. The wall outlet has a voltage regulator as do most handheld electronics. so Its not going to get 120v lol. You good

Where do you place clips to find clipping on head unit brotha just bought one
On any speaker output coming off head unit. Can be left front speaker, right rear, etc.
Don’t know if you saw this video yet. But it will help: ua-cam.com/video/1R7QE0bqztQ/v-deo.html
What if you have an amp connected to my speakers already how would I check for clipping on head unit ?
@@josecunsako31 I suppose you'll have to tap into a speaker wire from head unit. Then do each channel for your doors from amp to set gains

Hi, can you help in something I don't know if I'm doing something wrong, but today I try to set my amp gain with the $40 Oscilloscope and I couldn't make it work right the sound wave was all over the place 😅 how I do it was playing a 40hz test tone at my max volume with out distortion since I'm using a external EQ I did my sound setting there and I maximize my bass level and also my epicenter level and in the Oscilloscope my settings was 10v and 5ms and when I play the tone and start increasing my gain just so little the sound wave was all over the place I couldn't get a clear view, then later I did the test again but only having connect my head unit just to the amp amd it work just fine I don't know if the epicenter is maximizing the signal too much or I just don't know how to set my amp gain having connected and epicenter and a external EQ can you help me!?
Man that is strange.... if you were adjusting the settings as described in the video and still nothing I’m not sure what it could be... might be the epicenter which is the only real variable.... but not 100% sure. Sorry man:/
@@NextLevelCarAudio yeah I think the epicenter is the problem it would be fine if I set my gains just adding the EQ and when I'm done I just add the epicenter you think it would distor my sound? I have the epicenter because 90% of the music I listen is Spanish and one last question what it means when the sound wave on the Oscilloscope reaches the top and still there's no distortion? It distors when it reach the top? Because the sound wave gets flat when it gets to the top
That could work.... if the wave is still not distorting before the top. then try setting the setting differently on the scope sonic clips half way up the screen. That way you can see it and be sure
@@NextLevelCarAudio I would try it like that thank you!
How it on brasse amps
Not sure, but should be fine with all
Also, I bought one from Amazon lol
I think it's unfair too ues ones product and mass produced these units to sell at a very expensive price for what is a simple light the smd dd1 is good for what i does but Steve should be ashamed for over pricing a piece of equipment that only has a light no screen and advised everyone that they need he's product so he can continue too live out his expensive life style. I bought one because i too fell into the track . I repair and install and modified car audio and im a electrician as my job i been installing car audio since i was 12 and since then i love car audio i remember the real and fun reason the days of car audio and electronics and it's why i made my hobbie too learn it i will simply say dont believe the hype i uesd the tool that cost me up too 200 plus shipping with a cd and a blinking light knowed as the smd dd1 and i returned it the next day reset my gains in my system and too my ears i was more pleased with my sound again i noticed that my gains were a little lower than with tool . The car audio and sales is all about making money now . And selling cheap products made and deigned with cheap parts what does matter if it says made in usa with cheap parts from China. People stop making these con artists rich they over price there gear and boasting there worth all over the internet. Car audio was never about money it was about music and joy and products that were way better than todays junk for half the cost i should know i been repairing amps and electronics since i was 17 in fact my amps are modified and are old school Components cause i know how well they outperform todays way over priced junk back in the day you did get what you payed for.
I can only find 50hz -5db
DJ rusticals has free test tones. Check out his site
How about this little old scoped over a year ago it's been working amazing
Awesome!
the cheap scope cant handle more than 3,000 watts being thrown at it. So i switched to Liumy.
???? I set and confirmed my gain on my crescendo 12k that puts out over 15,000 watts. Verified with bench scope and with SMD AMM1....
Not a big deal but I did this with my multi meter and did get .5 volt higher on channel 2. Same with channel 4 vs 3.
great cheap tool
Do you still have the speaker for sale?🤣
Hello, I am new to car audio. I bought a cheap oscilloscope from Amazon like the one you have and tried to check my mono block for clipping. I wired everything according to how you explained. I turned the gain all the way up and the scope showed no clipping. The signal went up some and that was it. I feel like something is not right because I have 2400 watt at 1 ohm amp wired to a dual 4 ohm sub. If you can help me figure this one out, I would gladly appreciate it.
Yeah, that’s not right. Is volume at head unit turned up to 75% or max unclipped volume during the test?
That quimat oscope is like $110 noww
Wtf? For real? That sucks
🤣😂 $ 20...
??? I’ve seen the unassembled units for sale for $17/$18 right now available. So yeah, for $20 and a little work to assemble someone can have themselves a perfectly working o-scope
@@NextLevelCarAudio i think he was referring to you saying $20 for that test speaker that blew up.
@@NextLevelCarAudio lol.. yes the speaker that blew . It made me laugh when you said speaker blown now it's for sale.. .. as for the O- scope I took your advice from previous video & got me one..
I forgot about that lol. It is still for sale tho! Lol 😂
Put your sine wav in the middle of the screen on the pocket oscope so you can see the bottom.👍
Great video, thanks again
I usually set my gains with a 0dB sine tone as I listen to a lot of non-mainstream trap/EDM. Is there something I can use to figure out what the maximum dB is of songs that I listen to, or can you recommend a dB sine tone I should use for my requirements? I know -5dB is the default but I'm not sure if this might be too much or too little and I'm really looking to maximize my gains. Thanks so much for any help you can give!
I use 0db as well. I also listen to a lot of bass boosted music. I don’t have that knowledge of how to do what your asking. Sorry bro. Maybe someone else will chime in
Awesome presentation! I'm new to the car audio world and I bought a Rockford Fosgate Prime R2-750X5 that has C.L.E.A.N. in and out technology that lights up red when it detects the signal is clipped so you can back it off and avoid distortion. What's your opinion of that tech., do you think I should still go buy something like that $40 oscope to double check?
It is a good system. Like a clip indicator on a amp or bass knob. Gives you a good baseline. Does not hurt to double check. I’m releasing a video in a couple days talking about tweeter method. It is a anywhere from free to dirt cheap to perform and is very accurate
Would you mind doing a video and showing us step-by-step exactly how to set up the small Ascope in the settings because I cannot figure out how to get my graph to match yours I want to follow you along in the video and I’m super frustrated I can’t find that information anywhere, just need a step-by-step how to set it up to test it like this.
So I test subs and mid range speakers with 40 hertz and 1000khz with tweeeters ?
That’s what I do
What if you have components and the speakers are wired together?
For my main speaker not subwoofer what sign wave should I use ?
Setting distortion by ear is simply not possible. Distortion is occuring before any audible change occurs that the human can hear.
Just ordered my o scope, can't wait to not have to rely on my ears😭
does anyone know how to change the frequency on one of these units?
Hi bro i want this o scope.
Can u give me link where r can buy....
