Driving home from work on a crystal-clear day earlier this week, I rolled the windows down and jammed out to some of my favorite tunes. But about halfway through the first song, I realized something.

“Man, this sounds like #!*%.”

It was frustrating, to say the least. I drive a vehicle manufactured in 2025. This isn’t my old beat-up Camry we’re talking about (no shade to those still holding on to a Camry). My speakers should sound at least OK. So, I did what I always do and got to researching. In this situation, most people blame their speaker setup, but the real culprit is the Bluetooth connection and a few tiny settings most people don’t even know exist. Here’s why your car’s speakers never sound as good as they should, and how to fix it before spending a few hundred bucks on a new setup.

Bluetooth puts a squeeze on your tunes before they hit your speakers

It plays telephone with your favorite songs

To put it plainly, Bluetooth compresses your audio before it reaches your car’s speakers, and while there are both good and bad types of Bluetooth, most cars support only the most basic codec—SBC. Some cars even play music through the phone-call channel, which further degrades your audio quality.

If that sounds like your situation, there may be a fix. First, check your car’s supported Bluetooth codecs in the owner’s manual. Then, make sure that “media audio” or a similarly named setting is turned on in your car’s infotainment settings. Finally, forget and re-pair the phone to the infotainment system, and that should fix the issue. If it doesn’t, though, aftermarket head units can handle a better connection, and they may not cost as much as a full speaker system swap.

Your settings could be working against you

Your phone is whispering, your car is yelling, and your music app is being cheap

With some primitive Bluetooth connections, you can control your car’s volume with your phone’s volume (and not in a good way), and low phone volume plus high car volume can create a hiss that is pretty annoying to the ear. Also, depending on the streaming app you use and your phone’s signal strength, some apps switch to lower-quality audio to queue up your next track.

When that happens, the phone EQ, the car EQ, and the app’s EQ can stack together in a way that turns your audio into what’s essentially a pile of mush. But what’s the fix? Well, there are multiple. First, if your car runs on a basic Bluetooth connection, make sure your phone is at full volume. Then, adjust any settings in your streaming app to keep the audio as high-quality as possible. Finally, make sure that you flatten every EQ except the car’s. This will ensure everything comes through as clearly as possible.

Something in your car is running interference

That cheap gas station charger is sabotaging you

Is your cabin full of neat little gadgets that you love to tell your friends about? They make great conversation starters, but in reality, they could be throttling or interfering with your Bluetooth connection. Some of these plug-in gadgets can cause static to bleed into your audio output, create a buzzing noise from interference, or even cause your wireless connection to drop entirely.

Luckily, this is the easiest fix on the list. Simply unplug or replace these gadgets one at a time, and listen as your sound quality improves with each new addition. If that’s not feasible, though, unplugging them when they’re not in use could likely fix your issues if they’re related to your other devices.

Skip Bluetooth entirely if you can

Maybe the cord was right all along

What’s the best way to get around a shoddy Bluetooth connection, you might ask? Avoiding one altogether. When you plug your phone into your car’s infotainment system, it sends audio through the USB connection instead of through the air via Bluetooth. That way, you avoid the compression required for Bluetooth audio. That said, Apple CarPlay and Android Auto both use Wi-Fi for wireless audio transfer, which usually beats Bluetooth.

If you have an older vehicle, an auxiliary connection is a perfect fallback and can handle similar data to a USB, again, with a caveat. If you’re still using a traditional FM scanner with an auxiliary input, like I had to in my old pickup truck, those tend to sound worse than Bluetooth in the first place. Want to test it out? Pick your favorite song and play it over your car’s stereo with Bluetooth. Then play the same song via USB and see if you notice the difference. If you can, you might be an audiophile without even knowing it.

So, as a final reminder, if your car’s audio doesn’t sound quite right, there’s a good chance the issue is your Bluetooth connection, not the speakers themselves. Personally, I always opt for a wired connection now on my road trip jam sessions, and I recommend you do the same.
