I have a 2007 fusion SEL with navigation and the audiophile option. I'm not satisfied with the overall sound quality. I would like to upgrade all the speakers and add an amp to power them running about 70 watts RMS to each speaker. I would like to integrate this with the factory head unit as I don't have any issues with it other than the sound quality. I like the functionality and want to keep it the way it is. I was doing some reading on this forum and it sounds like a sound processor, like JL Audio's Cleansweep, would get the job done but I've never used one before. Would going this route give me good sound quality? If I were to go this route, where would I get the front and rear signals? I would assume that the rear door speakers get full range signals but what about the seperate tweeter and woofer in the front?
