Tips on How to Make Subs Louder Outside the Car
You can make your existing subwoofers louder without buying an additional amplifier. Check out;
1. Set the Cones Facing the Car Roof
Airflow compromises bass-reflex effects on subwoofers. You should leave a clear space in front of the cone for your music to reach the streets.
The best way is to lay the enclosure flat on the back seat with cones facing the roof. Air will flow freely, and the music will reach further.
Ideally, you can fold the rear seats if you don’t have passengers. More space will make them even louder.
2. Use Multiple Subwoofers
If you have one subwoofer, you’re doing it wrong. Combined cone surface areas will push the air better.
Further, the more the rms and watts, the louder the bass. You can bridge the amplifier or lower ohm impendence on your speakers. You’ll create earth trembling tremors on streets.
3. Have a Ported Subwoofer Box
A sealed enclosure will amplify the sound waves from the cones’ back with the front waves.
It will generate loud audio with the effects of someone blowing through a bottle. It’s usually loud.
Enclosures are usually cylindrical or rectangular. With either shape, it’s easy to install them around the car.
This flexibility will allow you to tune and set your subs to boom and produce maximum sound.
4. Turn Your Subs to Face the Trunk
Another option from facing the car roof is the trunk. The lower the frequency, the longer the wavelength. And this is achieved by directing the cones to the back.
The bass is mostly well balanced because the trunk will amplify sound inside and balance the outside.
However, setting the subs facing the back seats is wrong. And keeping much cargo in the trunk isn’t right too. Neither of these will give you the best outcomes.

5. Feed the Subwoofers With Enough Power
Subs are naturally power-hungry. They are designed for loud music and bass. You should be ready to supply them with enough power.
If they are underpowered, you may overwork the amplifier to make the music louder.
Check on your amplifier to avoid clipped signal to the subwoofer. It will be a mess.
6. Sound Deaden Your Car
We all believe sound deadening a car restricts sound from getting outside. But there are special ways you can do it to increase the sound from outside.
Frankly, a car has many internal components like the upholstery, toolboxes, and spare wheel in the trunk. Most materials are made of fabric which may tamper with sound wavelength.
To get rid of noise and excessive vibrations, you need to sound deaden your car. Here is how to make a subwoofer have more bass by soundproofing the car interior;
- Target the floor since the floor mats and the carpet may have a higher impact on the sub sound.
- Install the soundproof material around the roof because most roofs are made of fabric material.
- Door panels also absorb most of the wavelength, preventing it from getting outside.
- Sound deaden the trunk too but be careful with the door spaces.
Siless liner 157 mil is the best car sound deadening material. It has closed cell foam and a heat blocker. Further, it’s lightweight for the car interior.

7. Roll Down the Windows and Open the Sunroof
When the bass strikes harder, the sound waves will go out easily with open windows.
To prevent excessive wind from blowing and affecting the engine performance, leave a little space on the windows.
You can leave the sunroof open provided it’s not winter season. You wouldn’t want to freeze trying to gain street attention.

8. Properly Tune the System
The last tip on making sub louder is properly tuning your system. Play around with the system to get the exact sound you need.
However, you should be very careful to balance the bass and your audio.
- Set your amp’s gain.
- Adjust the subs gain and low-pass filter.
- Adjust the subsonic filter and the bass boost.
- Finally, match the receiver volume with sub-level.
Play with the knobs until the distorted sound turns clear and louder from the outside. But be careful to note the maximum sound your receiver can deliver.
