My front stage consists of 1100.4, two PWX6's and crescendo super tweet in each door. Channel 1 has a tweet, channel 2 has a tweet, channel 3 has two 6's on it as does channel 4. I have the gains set with a DD-1 but when it comes to setting up the subsonic filter, crossover, HPF/Full/LP-BP im lost. Ive played with the settings while listening to music but I can barely hear a difference. I have a CC-1 on the way so I just need to know what you guys have these dialed in at.Thanks for any help.
