Just installed new car subwoofers but you’re not getting the kind of bass you expected? If you’ve invested in the best car subwoofer and its bass output is wanting, there’s probably something wrong in the setup. Essentially, subwoofers are specially designed to reproduce low frequencies. However, getting the perfect bass may be a challenge for some car owners. In this article, you’ll learn how to get more bass out of your subwoofer.
Invest in a subwoofer enclosure
If your subwoofer doesn’t have an enclosure, then you’re missing a lot on its capabilities. Enclosures work by allowing a subwoofer to produce an enhanced bass response. Essentially, you’ll need to choose between a ported and sealed enclosure.
Sealed enclosures allow for more accurate and tighter bass whereas ported enclosures allow for louder and heavier bass output. Here, your choice should depend on the kind of bass output you want. However, sealed enclosures are smaller in size and more ideal for cars with limited space. Ported enclosures are generally larger and may not fit in some tight spaces.
Regardless of the enclosure you choose, ensure it’s made of premium quality materials for the best performance. You can choose to build a subwoofer box or buy an aftermarket subwoofer. Ensure the subwoofer is properly designed and constructed. It’s recommended to fill the subwoofer enclosure with polyester fiber, cotton, or poly-fill for more quality bass output.
Proper subwoofer placement
Subwoofer placement is extremely important. The location where you place the subwoofer in your car cabin will play a major role in the overall bass output. Improper subwoofer placement can reduce the base effect.
The best location to place your car subwoofer is the trunk. The trunk is typically roomy and will allow for low frequencies to be heard throughout the car. Ensure it’s not positioned in a manner that it faces another speaker as doing so would lead to distortion and poor sound quality.
Upon placing your subwoofer in the trunk, move it from one position to the other until you determine the exact position where it sounds best. For some trunks and cars, the subwoofer may sound best when facing upward. In other cars or depending on your preferences, you’ll find it sounding best when it’s positioned facing the back or the front of your car.
Add an amplifier
Although some head units come with inbuilt amplifiers, they’re not powerful enough to drive subwoofers with sufficient power. Thus, you may not get the best bass output from your subwoofer without an amplifier.
The best option is to either invest in a powered subwoofer or buy a standalone amplifier. Powered subwoofers are easier to install as they come with a built-in amplifier. Thus, you can connect them to your head unit directly. However, powered subwoofers may not be the best option for a serious bass enthusiast. If you want serious bass output, consider investing in a standalone amplifier to feed the subwoofer with sufficient power.
When choosing an amplifier, ensure the RMS power rating matches that of the subwoofer. Essentially, the RMS power rating of the subwoofer should be higher than that of the speaker. Also, ensure the impedance rating matches. For instance, if your subwoofer has an impedance rating of 4 ohms, pick an amplifier with a similar impedance rating.
Make proper adjustments
It’s important to adjust various settings on the head unit and amplifier to get more bass out of your subwoofer. One of the most important settings is the equalizer setting. Ensure the low pass filter on the receiver or amplifier isn’t set too high as it’ll fail to send lower frequencies for the subwoofer to reproduce the best bass. Set the low pass filter lower until you get the best bass output.
Some factory head units may only have bass, mid, and treble settings. In this case, set bass to the middle position. You can increase it slightly but remember that setting it too high may introduce distortion.
Also, ensure the gain level is set properly. It shouldn’t be set either too low or too high. If it’s set too low, you won’t get deep bass. In this case, slowly adjust it higher but take care not to introduce any distortion. If it’s set too high and there’s distortion, slowly adjust it lower until the distortion is eliminated.
Also, you can flip the phase switch button on the subwoofer or amplifier from 0 to 180 or vice versa and leave it to the option that gives the best bass output.
Use high-quality audio files
The kind of audio files you play from your receiver largely determine the bass output from your subwoofer. If you’re playing music from highly compressed music files, you’re likely to get low bass quality. The reason behind this is that highly compressed music files have reduced audio quality. It’s advisable to use audio files in their original quality even though they’ll take more memory space in your flash disk, CD, or smartphone. Alternatively, you can stream music in higher resolution. If you must compress music files, use lossless compression techniques.
Install sound deadening material
Bass tends to be extremely heavy. A subwoofer pushes a lot of air to produce bass. As a result, there may be vibrations on the car panels that’ll interfere with the sound quality. Thus, consider installing sound deadening material in your trunk, door panels, car roof, and car floor. Sound deadeners work by reducing vibrations for an improved listening experience. Also, they absorb engine noise and road noise to improve your listening experience inside the car cabin.
Check the wiring
Several people overlook the car audio system wiring. Improper wiring may lead to poor bass output. Ensure you use premium quality connectors and wires when installing your car subwoofer. Also, ensure all connections are done right, including the speaker wire polarities. Improper connections may cause distortion and short-circuit. Also, ensure all connections are tight. Any loose connection may cause the sound to cut in and out.
With these tips and tricks, you’ll stand better chances of getting more bass out of your subwoofer. Whether you’re playing music from your smartphone via Bluetooth, streaming online, or using music files from a USB flash disc, you can get the best bass output from your subwoofer by following the aforementioned tips. Always use your ears when making any adjustments to ensure the bass output is boosted to your preferences.
