Tuning car audio test tones

It may seem as if they should be similar processes, but installing a new source unit , amplifiers and speakers in a car is unlike installing most home audio systems. It is not as simple as plugging things in and hoping they work. Proper integration of your new electronics into modern vehicles and their wiring is getting more and more complicated as complex factory sound systems become more involved. Your installer will include this setup time in the cost to install your system. What does system setup and configuration involve?

How to Use RTA to Tune/EQ A Car Stereo


Home News. What came back was a 1st place prize and a realization that car audio has still much to learn. Luckily, I was able to catch Helmuts in his busy routine to get some war stories from his Finland adventure! The European Mobile Media Association is the main European organization which promotes all things related to in-car audio and visual entertainment.

EMMA has many regional chapters and they do car audio competitions from time to time. These competitions are held in two categories — sound quality and maximum sound pressure. SPL is pretty straightforward, these guys compete whoever makes the loudest sound at a set frequency. I competed in the SQ category where car audio systems are judged mainly in terms of sound quality, but you also get points for installation and presentation as well.

To be honest, I also used to think that these points for installation are rubbish, but get this — everything in a car runs on 12 Volt power. Want to run a W amp full-swing? Your power lines need to able to carry Amperes. This is serious high current stuff and should the isolation fail on a cable, it will instantly weld itself to the chassis of your car and cause a fire.

So you need proper installation and fuses. This is what impressed me the most. EMMA judges have a very rigorous framework how they judge sound quality. To become an EMMA judge one has to go through a training course and prove their listening ability and technical prowess.

To find out whether a sound system cuts the mustard they use a test CD. Sort of. They also take notes whether apparent elevation changes, depending on the spectral content. This is very hard to get right, because only tweeters are usually mounted in windshield stands.

Some then try to run the tweeters lower, so they play more mids, others put mids there as well. Then you get a nightmare of reflections due to all the windows.

One discipline where I lost a bit of points is soundstage width. They also judge the frequency balance of a system, where I got very high marks. And they also give points for general joy of listening, which is where I did get the maximum possible. As if! Driving to Finland was a nightmare. Nothing sounded right, because my car was full of luggage and the system was tuned for an empty car. Once I got to the venue I emptied the trunk and found out that luckily a only cable had come loose from one of the speakers and the driver itself was fine.

I had about 5 hours until my turn would come to show off my system, so I also walked around to check out my competitors setups. Let me tell you, there were some cars where you could see that there was a truckload of money spent.

Sadly, many of them fell flat once I sat down for a test listen. I was able to find out who would be my main competitors.

One of them was even an EMMA judge himself. They remarked some things and I took notes. The brains of my system is a regular computer which runs a Reaper DAW where all of the filtering takes place via plug-ins. To re-tune a regular competition vehicle it would take hours, for me it was a matter of readjusting an EQ plugin.

Maybe next time. Yeah, we agreed that I had a slight rattling noise in the front doors. I tried to pry some info from them on what to improve further, but they basically said to leave it alone, lest I make something worse. Kinda agree with that. Last time the winner got points. And I got points, a highest score ever recorded in Finland. How did your competitors react? I mean, you were the textbook underdog if there ever was one. I have full digital control over most aspects of my system.

And I base my designs on measurements. This allows me to select speaker drivers, without taking into account things like frequency response flatness or sensitivity. The two guys who placed 2nd and 3rd were using super expensive drivers from Scan-Speak and Accuton. I listen for the very final soundstage adjustments. Everything else is based on measurements. If you leave data crunching to the computer the result can be much better, because the data volume can be extremely high.

Honestly, the guys who took 2nd and 3rd place had way better setups than I did, yet they stood no chance. They brought knifes to a gunfight. Sure, do the measurement with Reference 4 Measure and then run the calibration on a smartphone via an app. Heck, we could get a rental car next time and use that.

Audio Test Signals

If you want to visit a local KICKER dealer in your area, we recommend calling ahead to confirm store hours and availability. It matches the output of the source unit to the input level of the amplifier and features Gain Matching to prevent clipping the input. Next, slowly turn clockwise the gain on the amplifier up until you see the Gain LED light up or hear audible distortion, then turn it down a little. In any audio system, the goal is to reach maximum input and output levels without distortion or clipping. The engineers at KICKER have taken the guesswork, and hassle, out of matching the output voltage of your source unit to the amplifier with the Gain Matching feature. These test tones are sine waves meant to provide a consistent signal for the KX amplifier to reference. The different recording levels are designed to give you the perfect gain match for your application.

Music is powerful, and a fantastic sound system makes it even better. It not only protects your equipment but gives you excellent sound quality too. This also prevents the clipping of sound. Here are the step by step instructions to tune an amp by different methods. For this, cut off the power supply of the speaker. Then determine which terminal on the speaker is positive and which is negative. Record the ohm resistance visible in the multimeter. Remember, the resistance of maximum loudspeakers is 2, 4, 8, or 16 Ohms.
