JL Audio FiX 86 Sound processor for adding amps and speakers to a factory system — 6 outputs

You want to upgrade the sound system in your car with new speakers and amps but replacing the factory radio is just not an option. However, your factory system uses unusual EQ curves and preset time alignments that work well with the inexpensive factory speakers, but will prevent your aftermarket gear from reaching top performance. JL Audio's FiX 86 digital signal processor removes the factory system's equalization, crossover filtering, and time alignment, providing you with a completely flat and focused audio signal that your aftermarket amplifiers and processors can turn into high-fidelity music. Integrates into almost any system The FiX 86 gets its input signals from your vehicle's speaker wiring — no outboard level-matching devices are necessary. The FiX 86 automatically re-synchronizes any signals that have been time-delayed, returning precision to the sound. It takes your factory radio's 2-way, 3-way, or 4-way outputs, matches their levels, and combines them into six full-range stereo signals. Then 1/3-octave equalizers automatically flatten the frequency response, leaving the system ready for your custom processing and amplification.
