Improving the Sound of your SubwoofersThere are only a few things more frustrating to the ears than your car audio system producing hollow bass. When the bass output in your car is no longer music to the ears, it may be time to check, fix, or upgrade your speakers, especially your subwoofers.

If you are not an expert on car audio systems, the best thing to do is to ask professionals for help. Car stereo installation and repair service providers, such as Tri Audio Sound Inc., will figure out what to fix or enhance in your system, such as an amplifier that doesn’t have enough power to amp up your speakers.

On the other hand, if you already have basic knowledge of the system, here are some things you should consider doing:

Verify Polarity Compatibility

Before you start any project to enhance your subwoofers’ performance, verify first if there are minor issues you can correct. This is so you don’t have to unnecessarily alter your subwoofers’ engineering.

If your subwoofers don’t produce the bass output you want, it may be because of wiring issues. Positive wires should be in positive terminals and negative wires in negative terminals. If your speaker wires are reversed, the signal becomes out of phase, which means there will be oddities in the acoustics and bad bass response.

The easiest way to check for polarity is by using a polarity test tool, which doesn’t cost much.  When you have your wire in the proper terminal, your speakers and subwoofers will build upon the compressed air to create great acoustical energy and bass output.

Subwoofers and Speaker Setups

Install a Digital Signal Processor

If you have extra money and are eager to enhance your subwoofer performance, you can consider purchasing a digital signal processor (DSP). The device allows for time alignment, which is essential in the car to make sure the production of sounds from all speakers is synchronized.

To use a DSP, first, you measure the distance of each speaker with one another. Then, input these measurements into the DSP software, which lets you digitally delay the sound waves of the closest speaker so sound coming from all speakers reach your ears at the same time.

DSP also allows you to control crossovers, which lets you limit what range of frequency will be sent to different speakers. You can send high frequencies to tweeters while low bass frequencies to subwoofers. This also means your speakers only play frequencies they are designed for, preventing damage.

Change Subwoofer Position

Getting the best bass output is not just about the power of your amplifier and your speakers. It’s also about the location of your subwoofer box. To make sure your subwoofer is properly placed in your trunk, move it around. Then, test if there are phase cancellation issues.

It’s not just about where you put the box, but also which direction the speaker faces. If you are satisfied with the output, fully secure the box by properly bracing it to make sure your speakers don’t lose any acoustic energy.

With compatibility, additional devices, and correct placement, you’re sure to have killer acoustics that will put Nicki Minaj’s Super Bass to shame. Now, every time you cruise the road, you don’t have to deal with hollow sounds – you’re sure to drop the bass.
