Tuning a car audio system requires the use of an RTA and an RTA microphone. An RTA ( Real time analyzer ) allows us to use an equalizer and adjust each octave so that our sound system's output is more acoustically correct. We can also use an RTA to match the output of our left and right side speakers which helps to create a true center image from stereo sound. In this video I introduce you to the new AudioControl SA-4100i RTA microphone and show you how to use it to tune my car audio system's DSP unit.

Excellent video. I concur, please more videos like this, I am (and I am sure lots of people too) interested in knowing how to correctly tune the low/high-pass filters, which slope to use, Butterworth or LR, etc. also a bit of info on how to select the right polarity of speakers and how to find the right RTA curve for your needs. Thanks again Mark, your info is always first class.

@macgeek2112 7 лет назад

Recieved my SA-4100i a few days ago. I haven't had the opportunity to tune my car with it yet but I'm impressed with the quality of the mic. I was surprised that the CAF discount was still valid when I ordered it several weeks ago.

@tvalchev 8 лет назад

This is great. In my opinion, every car audio place where audio systems are being installed must have one of these. The question then would be if there is the right person who has the "ear" to tune the system. I hate to see/hear folks spending $$$ to upgrade their car audio and the end results are worst than the original with imbalanced freqs.

I installed my system 3 years ago, and have never tuned it. It's a class act installation with complete dedication and thoroughness. I don't trust local car audio installers for any advice or tune. This is where I'm at. Can I tune my 2 and 4 channel amps with the pioneer HU on my own? I don't compete. I just want to pull the best from the system, and justify any future upgrades.

@jameseberhardt3551 6 лет назад

I was wondering if you could do a video on how to tweak your DSP EQ curve once you have the time alignment and balanced EQ curve set? I have a great sounding system thanks to using the Audio Control DM 608 and JL Audio DM 900/5. I adjusted the curve to my listening preferences keeping with a rule of less than 3 db per octave between frequency bands (I am 1 db at most). My issue is that I have drums rolling up the left side of the dash and down to the right kick panel. Not sure why I have a stage that seems to be low on the lower right side. I had Audio Control remote into my DSP and run several tests and they could not some up with the issue. I double checked the door speakers to ensure the wires were secured. Also the volume levels were equally matched. Its a bit frustrating to have a rock solid image that seems to be tilted.like the Titantic going down. Its beautiful but... Also, how do you get the image to project out onto the hood of the vehicle? I had a car in the 90's with Image Dynamic HLCD's and 8 inch mid bass loaded into the floor. We got lucky with the staging as it was quite high and centered but it seems near impossible to get the depth with door mounted speakers. On a side note I am using Hertz 6.5 inch coaxial drivers @90 hertz x/over point. The tweaters are on-axis toward center point of the ceiling (I am going for center stage not the driver listening position) which are loaded into sealed enclosures I made using your videos for making the composite plastic speaker rings which I added fiber glassed pods to. The rest of my system is a single 12 inch JL sub and two Rockford 5x7's for rear fill. This is installed into a 2013 Ford F150 Super Crew. I am designing the amp rack but wanted to get the sound adjusted properly before fabricating the amp and DSP racks. Thanks for making these pro quality videos!

@jameseberhardt3551 6 лет назад

Found the issue..the factory pin configuration chart was reversed from 2010 to the 2011 model. e front and rear left speaker polarity was switched to assist in bluetooth issues. Oddly enough most tech sheets do not have this update.

@YourSoundPath 3 года назад

Hi Mark, thanks for your videos. I have a couple of points to add. If you use pink noise than you actually want to see the graph falling down at higher frequencies and not being flat. The second point is that RTA do not using a FFT prossecing. It is a variation of that measurement and you have to consider it in the tuning. The speaker polarity test is too variating regarding how you hold the microphone to the speaker. There is better way to check this using the DC voltage ( a AA Battery or couple of those if you test the woofer) to see if the membrane of the driver moving in the right directioin by applying the DC voltage.

@cgrenesh Год назад

Under RTA settings, what is the best for tuning with pink noise? Flat, A or C ?

@wozzatherockdog1778 4 года назад

Waited many years for standard type head units to build in adjustability. How long before we can adjust individual speakers without expensive hop ups? I’ve finally been able to drag my SA-3055 out of moth balls in recents times. No longer do I have to leave customers with mediocre sound. Great to see technology become cheaper. Though I do recall many years ago some upmarket head units had their own mic & pink noise generator.

@esmokebaby 4 года назад

Long time listner first time caller. I'm a fan. I've been updating the sound system in my 2014 ram 1500 since i got her last year. So far i've swapped out all the speakers with a slightly upgraded version and upgraded the wiring and added 2 subs and and amp for the sub and one for the speakers. I got a DSP in my price range the DSR-1. How do i go about adding two more amplifires so each one only controls one of the high lows and mids. I'm a little curious how i would go about setting something like that up as well. Any advice is greatly apprciated.

I have a 04 Fiat Panda 169 with stock a audio system which included a subwoofer under the pas angers seat. I will be getting a new 2d 7'' head unit and want to also replace the 8 speakers. 4 tweeters and 4 subsw speakers. The stock subwoofer is quite nice and has a good thump, which I love ;-) boom boom. The doors hold 6.5 and the tweeters are 1'' so my question is which speakers would be best for the my car that delivers a good thump boom ting :-o Since there is a plethora of speakers and opinions, I was hoping you could direct me with your expertise wisdom in the right speakers. The Panda is like the Fiat 500 but nicer :-D Thank you so much for your help, Cheers.

@bongospank8321 2 года назад

I am getting new head unit which fairly deep independent front/rear eq (and new sub / amp / speakers), but this is an audio mix-check reference system, so I want a fully dialed target curve to be achieved when all head unit sliders at +/- 0dB so I know exactly how and where I am deviating from target curve if any sliders engaged. So... do I need another inline EQ to dial in that target curve according to the RTA measurements, or (on a relatively tight budget) is there some better way like more advanced amp or other item that lets me do that plus dial in crossover points or otherwise correct any imbalances? Also, for convertible, do you do two sets of RTA measurements (open and closed top)? If so, how do you handle switching system when top opens/closes?

@1marcelfilms 2 года назад

What if instead of a DSP you applied the EQ setting to your mp3 files with some program? or eq APP on the phone? Then it would be extremely cheap!

@CarAudioFabrication 2 года назад

It doesn't really work that way because you would only be correcting a left and right channel. Not the multiple channels needed for every speaker in a build

@TimothyArmstrongamblixVR 2 года назад

@CarAudioFabrication 6 лет назад

+Yang Du tune with one. Any fancy mic array is just going to average to one central position anyhow.

@yangdu 6 лет назад

Thank you so much for your reply! The issue is how to EQ with two mics. Should I use left mic to EQ left speakers, and right mic to EQ right speakers? The reason I'm thinking about using two mics to EQ is because I found with a single mic that the EQ changes when I sit inside the car.

@yangdu 6 лет назад

Also do you know how to tune a system with center channel speaker? I think a system with center channel is better because we don't just want the driver side to sound good. The issue with aftermarket car audio nowadays is it seems like nobody knows how to tune a system with center speaker. How to EQ? How to set the volume of each speaker?

@smiter102 3 года назад

@@CarAudioFabrication Hey thanks for the reply! Sorry but im still kinda confused. @5:16 you say you adjust one single speaker at a time and that you start with a tweeter. If you have an amp with only 4 channels running 4 woofers and 4 tweeters in a typical FL FR RL RR setup, this means that on each of the 4 channels you have 1 woofer and 1 tweeter receiving the same signal. How would you separate woofer and tweeter signals in the DSP? Dont you need each speaker to have its own dedicated channel (IE an 8 channel amp)? Or do you just unhook the woofers while tuning tweeters, and then vice versa? (using a passive crossover to protect tweeters of course) Thats the only way i understand how to tune 1 at a time.

@mikkolaine4883 2 года назад

@@smiter102 , he meant he has them active so every speaker has their own amp channel. If you have passive crossovers, you need to tune the EQ with mid and tweeter together.
