Video: JBL MS-2 Car Audio Optimizer
Zak Billmeier grew up in southern Vermont and coastal Maine. After graduating from Mary Washington College with a Geography degree he still isn't sure quite what to do with, he eventually settled in the mountains of Central Virginia. He spends his free time chasing his daughter around, taking pictures, gardening and cooking. He joined Crutchfield's car A/V writing team in 2007 and is now a lead producer on our video team.

Heads up!Welcome to this article from the Crutchfield archives. Have fun reading it, but be aware that the information may be outdated and links may be broken.
The JBL MS-2 is a portable digital signal processor that improves the sound in your car when you use a portable player like an iPod. It does not require permanent installation, so you can take it from car to car. It'll clean up your factory sound, even "premium" amplified systems. And it also works with aftermarket systems, including those with subs.
In this video, we hook up an MS-2, run through a setup, and then switch back and forth between the factory stereo and the optimized audio from the MS-2. Put in some earbuds or don a pair of headphones to best hear the difference.
