New sub box, change settings on amp?

[95lincdog]

My box is tuned to 34hz, should I have the low pass filter adjusted to (around) 34hz too? Or is that different? Where should it be at?

80.

The low pass filter is how high you want your sub to play. It only filters the low end spectrum hence the name low pass filter. If you low pass at 34 hz, it will sound like the sub almost doesn't exist. I don't even think most lpf will even go down that low anyway. Just stick with 80. Also, make sure to have your subsonic filter to around 25hz since your box is tuned to 34 hz.
