As automakers continue to abandon the stand-alone, standard-sized head-unit in favor of integrated designs, JL Audio’s product development team felt that a need existed for a high-quality integration solution. This product would need to deliver world-class audio results while not interfering with vehicle functionality, safety or reliability.

To this end, we embarked on a two-year project to develop the CleanSweep® CL441dsp — DSP-based solution that permits almost any factory-installed audio system to serve as the source for a high-performance aftermarket sound system.

If you own a newer vehicle, like the ones shown here, chances are that the head unit is not easily replaced due to cosmetic or functional concerns. This doesn't mean you have to settle for whatever audio quality your vehicle manufacturer decided was "good enough".
By accepting, processing and controlling the audio from almost any factory-installed head unit or amplifier, CleanSweep® makes virtually any modern vehicle a candidate for high-end sound, without costly fabrication, integration or radical surgery to the dashboard (and without needing to purchase an aftermarket head unit).
Think of it as freedom of choice wrapped in black sheet-metal.
