besides audiocontrol, who makes a good electronic crossover?
i'm looking for something that is 4-channel with at least 18db crossover slopes, preferably with some kind of bass enhancer. in-dash would be nice. i'm familiar with audiocontrol's line of products; i like the three.1, HPX, and EQX. however, i'm not familiar with any other good lines. any suggestions? thanks for the help.
