Properly tuning your car’s audio system can make music playback sound better — if you’ve ever explored your receiver’s various knobs and settings, that much is obvious. It’s finding those proper settings that proves a challenge. In the hands of an expert, tuning your car audio can make your music playback sound much, much better. The following expert tips will give you an idea of what you’re dealing with.
Make sure your car speakers are in phase
Car audio experts like to describe the stereo listening experience as a sound stage, meaning that a properly tuned car audio system should create the illusion that a band is playing in front of you, with lead instruments coming from the left and right, and with the rhythm section and vocals centered right in front of you. If your speakers don’t create this impression, the culprit may be your speaker wiring. When the positive and negative wires connecting your speakers don’t match, one speaker will be vibrating forward while another vibrates backwards.
This is what’s called being out of phase, and it can suck a lot of the color out of your stereo playback, especially in the lower frequencies. An easy way to diagnose this issue is to turn the balance knob on your receiver all the way to the left or right while playing a piece of music. While listening closely to how it sounds, turn the knob back to the center. The bass should sound noticeably louder when your balance is centered. If it doesn’t, then your speakers are out of phase.
EQ for clarity
When listening to any piece of music, the goal is for the bass, mid, and treble frequencies to play in balance to one another, so that the music sounds most natural. To check your balance, start playing a piece of familiar music, and listen to the lead instruments and vocals. If they sound dampened, or like they’re playing in the background, your mid-range is out of balance. Using your car stereo’s equalizer, add boost to your mid-frequencies (around the 400-1000Hz range) to bring these sounds forward, to preserve your sound stage.
Conversely, if the drum cymbals in the recording lack sizzle, or sound muffled, you may need to boost higher frequencies. Higher range frequencies don’t travel as far or fill space as much as lower frequencies do, so depending on the configuration of your car, the problem could be that the tweeters are physically installed too low to compete with other components, so rather than a boost, the best solution may be installing discreet, dedicated tweeters.
Find the right amount of bass
We’ve all witnessed that car with huge subwoofers, driven by a proud someone who turns the bass up so high it vibrates the whole block. That’s a fun idea, but it’s not how experts would tune a stereo to bring the best sound out of the music. To set the proper amount of bass, use your equalizer to turn down the low frequencies all the way. Then, while listening to a favorite piece of bassy music, slowly raise the bass level until it the song sounds full again, and the sound stage sounds complete. You can always bump a little higher if you’re looking for extra boom, just make sure it doesn’t drown out your midrange again.
Meanwhile, if you have a dedicated subwoofer that makes it sound as though the bass is coming from in front or behind you, you may need to adjust its crossover frequency. Even following the sound stage model, when it comes to true bass frequencies, generally in the 20-100Hz range, you should be unable to tell which direction the bass originates. If you sense which direction it’s coming from, then some of your mid-range is coming through your subwoofer, which will. Make it tougher to accomplish that expert tuning.
