Yeah i have my subsonic filter off now. Thanks Julian, what state do you live in ? Does your dad own a car audio shop ? You need to go to ebay and click on sell and follow the directions. Its actually very simple. I have a headache right now but ill be back to answer more questions.

MO, with sealed box, subsonic filter is not useful cause of the flatter frequency response curve. You can however still use it. Set it around 18Hz.
