The Merits of a Subwoofer in the Car’s Rear Speaker

Better bass response

The company manufactures the factory-fitted subwoofer in the car audio system to expand the bass response of low-frequency sound in the music played in your car. However, it doesn’t produce enough bass response; it usually enhances the sound above 50Hz but doesn’t go below this limit.

Thanks to an aftermarket subwoofer, a better bass response is possible for your car to produce a shallow frequency of around 20Hz.

Reduce in distortion

The vibrations caused by speakers and amplifiers usually create a distortion. To reduce this distortion, you will need a high-quality subwoofer in your car’s speaker. You can enjoy your music with high volume without distortion, even if your favorite music contains nothing but bass.

Greater clarity in sounds from low to high frequency

This sound clarity is an excellent property, which helps produce the fastest response to the bass. It makes tight bass sounds very clearly due to its superb quick, responsive effect. 

Full-spectrum response

A good quality sub for the car will help your speaker system create a full spectrum without putting too much load on the speakers. With a full-spectrum response, your speaker will get the power to produce the high to mid-range frequencies with the best clarity.

Having less load on smaller speaker

With a car subwoofer, low-frequency amplifier, and proper bass management, your car will gain the full potential with your music. The car sub lightens the load for full-range speakers, improving their overall performance to better sound quality without distortion. It also relieves the smaller speakers from having significant loads for producing low-frequency sounds.

  • Sound pressure level: This helps subs to maintain the power it needs to produce the given volume. The more the SPL of sub means, the less energy it requires to make a sound.
  • Enclosure: You should shop the sub with a sealed enclosure as this design has a better sound quality. You can also purchase them separately.
  • Voice coils: Generally, the subs come with two voice coils, including single and dual. The dual voice coils increase the range of amplifiers that you can purchase and also help maximize their power.
