Hi. Anyone familiar with JVC HU's? There's something in the settings that's really confusing me. There are x'over frequency settings for tweeter/front/rear/sub but there are only 3 sets of pre out's for front/rear/sub. So how could the tweeter have its own x'over freq, when there is no pre-out for a tweeter? Check out the screenshot of this page from the user manual. I am using the 2-way crossover setting items.
