Does the subwoofer output work with an internal (fixed) crossover, or should the crossover on the subwoofer be used?
Both of these solutions are possible. With a single D-Premier, using the subwoofer output, you use the crossover on the subwoofer. To activate the subwoofer output, you have to configure it on the website and to put the configuration on the SDCard provided. It is very simple. If you have 2 D-Premier, you will be able to configure easily a multiamp. An amp can be dedicated to basses. There is an internal and entirely customizable crossover within the D-Premier.
