If you went by Pimp My Ride episodes, improving your car's sound system involves buying a new head unit, speakers, amplifier, TVs, an extra gaming console, etc. Fortunately, JBL's engineers don't watch MTV, so instead they came up with the JBL MS-8 System Digital Processor ($800). This non-intrusive box packs a powerful digital signal processor offering digital sound processing equalization and DSP time correction, optimizing up to eight channels of sound using an included headset. Other features include an LCD display, wireless RF remote, preamp controls, and a graphic equalizer with 31 bands.
