Anyone looking at this video for education purposes he does a more in depth video than the person who makes the product! This video is your best bet for setting your gains
I know this is an older video but if you wanted to keep some of your speakers at -0db then you wouldn't need to use the overlap function. You would simply play the 1k hz -0db tone and back off the gain until the distortion light is off and your done.
Of the whole youtube this is the best explanation ive got of how to use smd thank you very much even the founder didn't give a clear explanation of how to use it I thank you again bro
i don’t know any of this, but i am going follow your method. No overlap on mid & high amp, plus 5 db on subwoofer amp 😅. thanks for the tips, very useful at least you gave a baseline of what is good sound.
Yes sir ! Always want to have your mids & highs to sound clean ! No distortion or clipping at all ! Just crystal clear. For your subs if you are looking for just pure sq keep it at 0db no overlap, if your subs are a bit underpowered you can clip to your liking , id say 5db 🤷🏽♂️, if they are overpowered (in my case) i keep at 0db . I tried to do 5 overlap but the clipping started making my subs stinky. All depends on your setup bro
@@SleepyBoiii i search all over to give a better explanation of how this dd1+ works but all i see people just turn up randomly without explaining why? i just set to no overlap because i just want to listen to good music. i don’t need my system super loud that can be heard down the block.
So first you set it with the SMD dd1 then the black smd crossover for frequency??? Thanks bro your vids are the best for instructional videos keep em coming your Tahoe looks good too what u got 2 mechman 400 alts and which batteries do u run them alts to run the vehicle or just power the system what's your voltage at on Tahoe?
Question after setting your gains and overlap on the amps I notice you put your deck/stereo flat. After setting your gains and overlap do you mess with the bass/mids/treble to adjust the sound or does that defeat the purpose of setting your gains in the first place. I notice everyone that has done videos never mentions if you are able to go back to the stereo and adjust your settings
Yes you can go back always go back to your hu & change a few settings.. Just dont go too crazy with it or else it will defeat the purpose of setting the gains. If you have a 7-13 band eq on your headunit even better. Just dont get to crazy on your eq
@@SleepyBoiii ok thanks nice to know. Usually on my head unit I turn down the bass all the way down and miss like -3 and treble usually higher but currently only have a sub with an amp and aftermarket deck. I just bought all new speakers and amps so this helps out since it's like starting fresh
@Sleepy Boiii Is setting the crossover switch to flat, the same as setting it to off on some amps? Thanks bro. Also on a stereo that has the option for sub level, should that be turned all the way up along with bass volume knob when setting the amp gains?
Wouldn’t you be better off using a tone generator from an iPhone vs using the CD from SDM? Most people play music through their phone via bluetoooth. Seems the best practice would be to use the same tones, but through your iPhone with the volume all the way up on your phone first, and then test your head unit volume for distortion level. Thoughts?
I'm trying to understand more and more of the little details, when it comes to turning the low and high pass filters up and down respectively, do you just leave them there? Do you tune those at the radio if available, or are they usually fine where they're at for tuning with the DD-1? Thanks.
Yes you usually leave them where your dd1 sets it to. You can also set your crossovers on your headunit. All up to you though. I personally set my amps & headunit crossver since i do hear a difference then just setting them on an amp.
Great video, Do you need to have a amp that matches perfect with your woofers, Meaning matching RMS? Seems like gain overlap is not meant for amps that are higher in RMS than woofers? Example- 1200 watt RMS amp combined with 600 watt RMS woofers. By the time you get to clipping wouldn’t it be wayyy over powering the woofer? Any information would be gladly appreciated.Thank you.
Yes, i wouldnt use gain overlap on a amp that is higher than subs. So in my case right now in my tahoe... i have 2 15s . Each subwoofer is rated at 1500 rms. I have a 5000w amp to both subs. I wouldnt use gain overlap in my case. Also subs can take more power than they are rated, sending clean power to them.
Thank you for replying so soon, So in your case do you give your woofers the whole 5000watts from your amp? Is there a percentage you use For example 3000rms woofer times 120% is 3600watts from woofers, Is there a calculation that you use to calculate how much power you give to the woofers before reaching max power? Or some type of rule of thumb?
Hello What kind of way should we follow when adjusting the amp gain, I used -3 db test tone for the whole speaker, except the tweeter, I used -6db for the tweeter, how do you think the gain should be adjusted as close to the music?
what tools can we get to help with setting rms or wattage. i have a more powerful amp for a weaker speaker. i dont want it that high. is there a tool to help with rms or wattage power and for adjustments?
Take whatever wattage you want to achieve and multiply it by the load of the speaker then get the square root of that number and that will be the volts you need to be at for that power. So example if I want to get 300 rms to a 2 ohm load I would do. 300x2=600 Then you do the square root of 600 would be 24.49 volts so use a multi meter with a o scope to achieve that wattage
@@SleepyBoiii hahaha yeah thanks again bro. Oh one more thing does the dd-1+ tell you to leave distortion on because thatbwould be considered 1% harmonic distort ion
I would do -3db . That way you can get a little bit more from your subs if they are underpowered. But remember, you can feed a 1500w rms subwoofer to 2500w - 3000w. With no problem. Just run clean power to them with no clipping (0db) and they should take it with no problem. All depends how the sub is built. I have 5000w running to 2 15s. 1500rms each no problem. They need more
If you listen mostly to corridos i would keep it at 5-7db depending on your subs. So it can hit a harder since corridos have really low bass. Try it with 7db if its not what you like try to get you a epicenter
Gain overlap is basically determined my the music you listen to... If you just want pure sound quality you would leave it at 0db overlap.. Which on the dd1+ shows "no overlap"... For your mids & highs i would recommend 0db because you want the cleanest crystal clear mids & highs coming out of your speakers... But if your speakers can handle the power you can lower your db and make your speakers louder... For subs its a bit different they can handle clipping alot more than speakers. If you just want clean bass keep it at 0db. Modified music (slowed, bassboosted, decaf) i would recommend -5db through -8db..

Appreciate it bro ! Tried my best to break things down. I Figured it out on my own & decided to share with all my people in the car audio game 💪🏽💯

make sure you check distortion from deck first then amps
I listen to Spanish corridors with a epicenter where do I set my overlap at

You can download the test tones from smd if you use Bluetooth.
I listen to a little of everything. What overlap you suggest? +5
Why do you hit read after the distortion light comes on. Wouldn’t u wanna do it before the amp is distorting?
Hey I have a Lc2i hooked up into a sub so I have to set the gains into that first but what do I tune up the AccuBASS or the bass knob it has
What do you set your hpf and lpf to when doing this please 🙏

Ok listen to corridos and rap what would be a good db set up for the bass amp
Me personally i would keep at a -5db
If my amp makes more rms than my sub is rated how much overlap should I do? 5-10
When your done setting up your gain do you turn down your frequency
Hello
What kind of way should we follow when adjusting the amp gain, I used -3 db test tone for the whole speaker, except the tweeter, I used -6db for the tweeter, how do you think the gain should be adjusted as close to the music?
Is it okay if I set my gains -5db 1000hz for midrange and -10db 40hz for subs? Thanks bro
Bro. How do you set hpf n lpf on fullrange amps for subs/bass?
Shouldn't u put the negative lead on the. Amps ground not the - speaker terminal? I always use the amps ground.
No, the correct way to do it is through the speaker outputs. It also says it on the instructions.
@@SleepyBoiii lol idid it on my dd1 like this works and my sub amp.
what tools can we get to help with setting rms or wattage. i have a more powerful amp for a weaker speaker. i dont want it that high. is there a tool to help with rms or wattage power and for adjustments?

And hey I listen to hip hop old classics and Mexican music is 0dB good to use
How do you use the dd1 on lc7i first
Do I use these same directions when tuning a 4th order enclosure?
Yes
@@SleepyBoiii if I don’t have a cd player how can I get the 40 hz over lap track?
My amp started smoking when I used my dd1
Thanks
Wouldn't you put it at -5db for sound quality when listening to decaf and modified music not +5
Correct, the dd1+ shows "+5db"... But in reality its -5db...
@@SleepyBoiii ooooo ok gotcha! That's where I was getting confused at fam lol haha
Haha yeahh i was confused at first but no problem
@@SleepyBoiii hahaha yeah thanks again bro. Oh one more thing does the dd-1+ tell you to leave distortion on because thatbwould be considered 1% harmonic distort ion
Do sub level supposed to be maxed or at 0 on the headunit?
All depends on your amp, i had to turn my down since taramp amps like 1.5 - 1.8 pre out voltage. They dont like more than 2v
So for good bass out of my subs what db should I run?
I would do -3db . That way you can get a little bit more from your subs if they are underpowered. But remember, you can feed a 1500w rms subwoofer to 2500w - 3000w. With no problem. Just run clean power to them with no clipping (0db) and they should take it with no problem. All depends how the sub is built. I have 5000w running to 2 15s. 1500rms each no problem. They need more
Do I set gains with car running or off?
Car running

What should you set it for corridos?
If you listen mostly to corridos i would keep it at 5-7db depending on your subs. So it can hit a harder since corridos have really low bass. Try it with 7db if its not what you like try to get you a epicenter

What overlap for hip-hop/rap ?
For subwoofers?
Sleepy Boiii yes, sorry for not clarifying. Unmodified too as well mainly just mainstream stuff off of Spotify
@@itsfusion9428 for unmodified music your safe zone will be -15db to -10db ... Modified is -8db to -5db

@@matthewgieling7842 yes , use the gain to set your overlap
