How to make car speakers louder without amp

Want to make your car speakers louder? Well, it's simple—get a good amp for your car audio system. That's what everyone will tell you.

But what nobody tells you is that a good quality amplifier can be quite pricey, and your budget might not allow you to get one.

And this gets you wondering…

"Can I make my car speakers louder without amp?"

The answer is, YES!

In this post, we have listed 7 simple but highly effective methods that will make your car speakers louder as well as improve your system's sound quality!

Let's get into it…

1. Use a subwoofer

One of the most effective ways of increasing the volume of your car loudspeakers involves investing in a subwoofer. Yes, a sub is a cheaper alternative to an amp and will do a great job of making your speakers louder.

For you to get the best out of your speakers, however, you'll need to place them in part of your vehicle, where they're not likely to experience vibrations and other forms of disturbances that might end up affecting the sound quality.

Avoid corner placement at all costs. Most audiophiles will recommend you to place your sub in the trunk for maximum bass production.

Besides placement, you should also ensure you fine-tune your new sub so that it's in phase with the rest of your system. This will help prevent competition for sound between your sub and the speakers—resulting in quality audio delivery.

2. Use sound dampening materials

Probably the reason why your car audio system emits low sound has something to do with the vibrations ad road noise that arises inside your car when you're driving your vehicle.

Luckily, you can take care of this by placing sound dampening (deadening) materials to your car panels. These will effectively lower the noise levels inside your car, thus increasing your sound accuracy and ensuring you enjoy high clarity in your music.

For instance, if you have door speakers installed in your car, they might be a victim to road noise and vibrations. This is because the thin metal tends to vibrate when riding, affecting your speakers' sound delivery.

Sound Dampening Materials

Now, if you attach dampening materials to the door panel, they'll deaden the vibrations to create a more stable environment for your speaker to output excellent audio performance.

Other parts of your car you'd want to dampen to lower the noise levels inside include the engine and floor.

3. Replace the speakers

You'll agree with me that the speakers you come with your car received the least attention when the manufacturer was building your vehicle. This means that your current audio system might not feature premium speakers. And this could be affecting the sound quality.

Luckily, you can get over this by replacing the speakers with brand new aftermarket speakers. You'll be surprised by the significant difference your new set of speakers will bring to your system. For instance, if you go for the best ​car speakers for bass and sound quality; you'll enjoy tighter bass besides higher clarity, and you'll even get to notice more details in your favorite tracks.

4. Replace the cables

Another overlooked factor that can heavily impact the loudness of your car speakers is the state of wires you're using to connect the head unit to them.

Cheaply made, undersized cables tend to affect the free flow of current from the unit to the speakers. The result is that your speakers get starved of the power they need to operate at their maximum potential.

Cables tend to lose their effectiveness with time.

Replace Speakers Cables

Regular checking and replacement of these cables will ensure you're always feeding your speakers with the right amount of power to enable them to perform at their best at all times.

If you haven't replaced your cables in a long time, take your car to a professional to have them replaced with quality ones. You might be surprised by the significant effect this simple change will bring to your car speakers.

5. Tune it properly

One common mistake most car owners make is maxing all their system's tone controls, believing that this will help make their speakers blast with cleaner and louder audio.

The truth is, this might give you clear sound on the driveway, but it easily gets distorted when you enter the highway. A heavy, low-frequency boost may end up putting too much strain on your standard system.

So, what's the best way to set your unit controls?

It's pretty simple; you tune them correctly.

Tune it properly

Let's say you want to get deeper bass from your OEM system. In this case, you can try using smaller bass boosts, lower the mids and highs. And then, turn up your overall level a bit more.

Even if you have already replaced your factory unit with an aftermarket stereo, we still insist that you avoid maxing the controls if you don't want your speakers to produce horrible audio.

If possible, consider creating a few EQ presets in advance. This way, you can try the presets until you find one that sounds great, depending on where you're driving your car.

6. Fine-tune the crossover controls

If your car in-dash receiver comes with frequency filters that work with your preamp and speaker output, then you can also tweak it to boost the sound that comes out of your speakers.

If you already have a sub hooked to your system, putting on the high-pass filters will help you remove low bass from your full-range speakers. This way, you'll receive what you've been missing—a cleaner bass.

Also, if you notice that your sub sounds as if the bass comes from behind, you can try experimenting with lowering and raising the crossover point on the low pass filter. This brings up the bass alongside the rest of your music.

7. Get quality ​audio files

One more thing…the quality of your ​audio files might be affecting the quality of sound your car speakers emit.

Compressing your files too much takes them closer to the low-quality edge. Too much compression of the files leads to loss of high and low-frequency info as well as some extra details. And this makes your ​audio sound disinteresting.

Whether you're using your smartphone, iPod, or mp3 player in your car system, we highly advise you to avoid as much compression as possible. The higher the bit rate of various tracks, the better the sound that comes out of your speakers.

For those who prefer streaming tracks from the internet, be sure to look for the option that lets you set the audio quality. Or stick to services that stream in higher resolution.

Final Verdict

If you crave louder audio in your car, but your budget won't let you invest in a good quality amp, it's still possible to make the speakers blast louder with an amp. We have offered you simple and affordable methods you can use to boost your car speaker's audio volume in this guide. Try a couple of these methods today to see which ones take your car speakers' performance level to their maximum.
