Check out our best-selling 8" raw drivers

Bass is important for good sound. In this article, we'll look at six of our best-selling and most popular 8" subwoofers:

  1. Bass on a budget – JBL Stage 82AM
  2. Versatile installation – Infinity Kappa 83WDSSI

Whatever type of music you prefer, to hear the full range of sound you'll need a good subwoofer. There's nothing like the experience of deep bass to make your favorite music come to life, and 8" subs give you the low, tight bass you're looking for in a compact, easy-to-fit package. But with so many subs to choose from it can be hard to make a decision, so we put together this handy list of some of our most popular 8" subs.

How to choose your subwoofers

There are a few specs you'll want to keep in mind. Power and sensitivity ratings tell you how well the sub handles your signal, its frequency range shows how low it can go, and impedance matches the sub to the power produced by the amp. For detailed information, read our Car Subwoofer Buying Guide.

The subwoofer enclosure is important, too

The woofer is only part of your bass system. The box you install it in has a direct impact on how your bass will sound:

  • A sealed box provides tighter bass that's more accurate; smaller footprint.
  • A ported box delivers bass that's louder and boomier; tends to be larger than sealed boxes.

Popular questions customers ask

It's simple. A subwoofer gives you more bass, reproducing lower frequencies that your other speakers can't deal with. And subs aren't just for "bassheads." Filling out those lower frequencies will make any kind of music sound better. At Crutchfield, we love to see that look of surprise and joy on someone's face the first time they hear a sub in their vehicle!

The larger the woofer, the deeper the bass. A 12" sub will play louder and deeper than a 10" sub. A single subwoofer is all it takes to reinforce your music, but if you're looking for volume, then two subs are certainly louder than one.

A sealed enclosure will sound tighter and more accurate. A ported (or vented) enclosure makes the bass louder, with more boom, but with a slight loss of accuracy. A bandpass box is a combination of those two designs for even more output in a narrow frequency range.

First, figure out where a sub will fit. If you have limited space, consider a small powered sub. You'll be surprised how much bass you'll get. Also, what are your plans for your sound system? A small sub and amp will work great for adding some bass to a factory radio, but if you have plans to expand your system, go with the biggest sub that'll fit.

Yes, all subs need an amplifier. Some subs even come with an amp built-in (called "powered subwoofers"), so you don't have to match the sub to the amp. If you prefer to customize your system, make sure to get an amp that's powerful enough for your sub. The more bass you want, the more power you'll need.
