whatever you want it to be at. for a sealed box it really doesn't matter all that much. just mess around with it til it's where you like.

I've woundered this too and have messed around with it alot anywhere from 40-140hz and cant tell a dam bit of difference. What exactly does it do, put more emphasis on the frequency its set to?

Assuming this thread is in reference to the lowpass frequency setting on the amplifier.....you are setting the crossover frequency for the lowpass crossover built into the amplifier.

As to the original question....set it to where ever it sounds best. This is not something that can be answered over the internet, as the best setting is entirely vehicle, installation, equipment, and listener preference dependent. Listen to some various songs that you are used to, and change the frequency until you find the setting that best blends the subwoofer with the rest of the system and maximizes the sound quality of the subwoofer and the system overall. Typically it is somewhere between 50hz and 85hz...but can be above or below this range depending on various factors. That range is simply a generalization.

No, i am not referring to the low pass filter. MY low pass filter is set to about 70hz. THis is a completely sepereate dial that just says "frequency". IF anyone has the kac-9152D heres the link to a pic of it. Its hard to read but its the dial next to the bass boost seperate from the amplifier. http://us.st11.yimg.com/us.st.yimg.com/I/millionbuy_1905_43530672
