Yes, I am trying to set up my aq2200d and I have a few questions about the different filter settings. Amp is hooked up to a single DD 2512 D4 wired to a 2ohm load(2.43 to be exact). Sub is installed in a a box built at 2.0cf before displacement with 44" of port turned to 38hz. I know how to properly set the gain but I am somewhat clueless on what I should have the Low Pass Filter and Subsonic Filter set at. Bass Boost will not be used so its of no concern. If you could give me any kind of advice on the filter settings I would greatly appreciate it.
