Car Stereo Subwoofer Selection Guide

By: Car Audio Professor

Whether you're considering designing 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 even a little bass will make a big time improvement in your overall system sound.

I'll never forget my first experience listening to the heart pounding sound of bass.I was listening to my friend's newly-installed system (he had a gang of 15's with a decent size amp), and it was literally shocking how loud 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.

A Few of the best selling brands are:

Hifonics, SPL, Legacy, Jensen, US Amps, MTX, JL Audio, AudioPipe

What type of bass do you prefer?

There are two main types in the sound universe: Sound Quality 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 songs. 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 ported 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 trade off. More bass obviously means more space. Usually speaking, ported enclosures will be to be 35- 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, yes, but it's different in that it will have a slight rise around the tuning frequency (35 Hz) and roll off very quickly. Both types of enclosures have real supporters. What you decide to use really comes down to your install and how they will sound in your car.
