Car Stereo Subwoofer Selection Guide

By: Car Audio Professor

When choosing to upgrade your car stereo system, adding a subwoofer can produce amazing results. Adding volume at low frequencies is like adding a third dimension to your favorite music. Whether you're considering building a new audio system, or just adding one subwoofers to your factory system, this simple addition will give you the single, most significant sonic improvement. Simply adding just a little bass will make a huge improvement in your overall sound.

I'll never forget my first experience listening to the heart-pumping sound of bass.I was listening to my friend's newly-installed system (he had a bunch of 15's with a decent size amp), and it was literally shocking how great it sounded, I was completely amazed that you could actually feel the impact of the woofers. From that moment on, I've been a car audio fanatic.

Some of the best selling brands are:

Jensen, Pioneer, Kicker, US Amps, MA Audio, JL Audio, Hifonics

What type of sound do you want?

There are two main types in the audio world: (Sound Quality, aka, SQ) and Sound Pressure Level.

Sound Quality refers to just that — a very linear response that's not boomy and is very controlled, especially when listening to complex audio. An SQ System generally uses a smaller woofer and requires a smaller enclosure. A sealed enclosure would typically work best for this application.

SPL, on the other hand, is for you “Big Bass Lovers.” If you're like me, and like a lot of impact with your music (extended bass response and 3 dB more efficient gain), then you're probably looking for a vented enclosure. The smaller the enclosure, the more pressure is exerted against the cone under movement.

With a sealed enclosure of predetermined volume, we can also predict the cut-off frequency and Q* of the system.

Sealed enclosures will also forgive minor mistakes in design (up to 10 percent), without major effects on sonic performance.

The main drawback with a ported enclosure is that the design and construction are not very forgiving of errors. Unlike a sealed box, you must determine a number of different parameters: the box volume, tuned frequency, port area, and port length. But, the advantage is huge — you'll get more output with the same number and size of woofers.

With all of that extra output there's always a compromise. More bass naturally means more space. Generally speaking, vented enclosures will be to be 35- to 40-percent larger than a sealed enclosure.

You're probably thinking, can a vented box sound as good a sealed enclosure? The answer is, yep, but it's different in that it will have a slight rise around the tuning frequency (35 Hz) and roll off very fast. Both types of boxes have true supporters. What you decide to use really comes down to your application and how they will perform in your vehicle.
