Message: [QUOTE="jdc753, post: 817177, member: 52"] Just take it slow and steady, and remember ONE step at a time, ONLY change one thing at a time, and each change is small and steady till you get it fine tuned. Just to add to GHO's post I am assuming your box is a sealed box right? If so I would honestly leave the subsonic filter off, or as low as possible. Subsonic filter is designed to cut off the extremely low frequencies, and this primarily comes into play in large ported boxes or extremely large sealed boxes where the sub is pretty free to play and could possible damage itself from over extending on the lowest of frequencies.
