Gold Member Username: InsearchofbassPost Number: 6734 Registered: Jun-04 | I like setting my lowpass fiters no higher than 80 hz but sometimes 70 hz is the best depending on the sub. As far as subsonic set it a just a few hz below port tuning if the box is sealed you probably wont need it set but test it to see. The bass boost I leave alone typically and boost sparingly off the headunit. The gain should be set by digital multimeter. Phase is set by ear and from my experience one way is usually tighter and the other is louder but less tight. |
