"Although, I haven't tried it on my own unit, I did ask a similar question of Pioneer on their FB page before the 80 PRS was released. According to them, if you are using network mode (high, mid, sub) the crossovers only work on the rca outputs. Not on the speaker level output. If you are in standard mode (front, rear, sub) the crossover works on both the rca and speaker level outputs.
Bottom line, if you want to use network mode, the speaker level outputs are useless."
