Kicker PXA500.1 amp help

EDIT. I just noticed the number of the switch is different from the actual amp and what the owners manual says. owners manual has them from 5 to 1 and on the amp there are from 1 to 5. the low pass filter switches and the input level switches are the ones im having a hard time figuring out where to set them?

I’m in the process of installing this kicker amp to run my Punch P2 10" sub. There are 5 dip switches on the bottom of the amp. Im not a real savey stereo guy so im having a hard time figuring out what is the best way to set these switches to run my sub. Whats the difference in Hz from 60Hz to 120Hz? I have attached a link to owners manual and switchs are on page 4. I will also attach a pic of the switches.

Switch

5) im setting to 12V

2) this where im confused
1) what should i set at??
