Our take on the JL Audio CL441dsp CleanSweep®
You can keep the look and functionality of your factory stereo, and still get outstanding audiophile sound with JL Audio's CleanSweep sound processor. It connects to your factory stereo's speaker lines and cleans up the stereo's output by sweeping away any processing from the stereo that could diminish the sound quality.
Many factory stereos use built-in equalization designed to make cheap factory speakers sound better, but this dressed-up signal can prevent aftermarket speakers from living up to their potential. The CleanSweep uses a 32-bit digital signal processor to remove the factory adjustments, then sends your external amplifiers a perfectly clean signal.
The CleanSweep connects to your factory radio's speaker wires, then takes the output of your factory radio and eliminates the peaks and valleys of the preset equalization, leaving a pure, unadulterated signal for your aftermarket amplifiers, speakers, and subs to work with. Your music will spring to life, with resonant lows, sparkling highs, and a realistic sense of depth and presence.
Keep all your factory radio functions
Since the CleanSweep attaches to the speaker wire outputs of your factory radio, it doesn't interfere with any factory radio functions like OnStar® or hands-free calling. Use the two sets of preamp outputs to connect your new amplifiers, and build your system from there. Best of all, you can take the CleanSweep with you when you purchase or lease a new vehicle.
Once you've connected the CleanSweep, pop the included CD into your stereo, and the CleanSweep corrects the equalization in as little as 20 seconds. You don't have to adjust anything the CleanSweep utilizes its built-in 120-band digital equalizer automatically, without the need for external control devices. The equalizer settings are saved in the CleanSweep's memory, even if you disconnect the car battery.
Adds an auxiliary input
The CleanSweep not only improves your sound, it adds extra functionality to your system. The built-in auxiliary input lets you connect an extra source, like an iPod® or a plug-and-play satellite radio to your system, and enjoy the superior sound quality of a direct audio connection. A remote-mount volume knob lets you adjust system volume and select your auxiliary source. If you choose, you can still use the factory radio's volume, treble, and bass controls as well.
The optional CL-SES source switch lets you expand the CleanSweep to accommodate up to three auxiliary sources. Some factory systems use more than just front and rear speaker outputs if you have a system like this, you'll need to purchase the CL-SSI Signal Summing Interface to merge the different signals so they can be processed by the CleanSweep.
