Car Stereo Subwoofer Decision Guide

By: Car Audio Professor

When choosing to upgrade your car stereo system, adding a subwoofer can produce massive bass. Adding volume at low frequencies is like adding a third dimension to your favorite tunes. Whether you're considering building a new audio system, or just adding or more subwoofers to your factory system, this easy 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 jamming to the heart pounding sound of bass.I was listening to my friend's newly-installed system (he had a few of 15's with a regular size amp), and it was literally shocking how real it sounded, I was completely amazed that you could actually feel the impact of the woofers. From that second on, I've been a car audio fan.

Some of the popular brands are:

Hifonics, Lanzar, Legacy, SPL, Rockford Fosgate, AudioPipe

What type of bass do you want?

There are two main types in the stereo universe: (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 music. An SQ System generally uses a smaller woofer and requires a smaller enclosure. A sealed enclosure would typically work best for this application.

Sealed enclosures are also known as “Acoustic Suspension” enclosures. When a speaker is placed in a sealed enclosure, the pressure becomes trapped in the box and restricts the cone movement, so the air inside the enclosure acts as a spring. 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.

Ported enclosures are very similar to a sealed enclosure in construction, but feature an additional opening for a port. Essentially doubling the effective cone area.

With all of that extra output there's always a trade off. More bass naturally means more space. Usually speaking, vented enclosures will be to be 30- to 40-percent larger than a sealed enclosure.

You're probably thinking, can a vented enclosure sound as good a sealed enclosure? The answer is, yep, but it's different in that it will have a minor peak 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 car.
