How to wire amp to sub?

What's the best way to wire this? What do I do with the high/low pass filter, the input sensitivity, the balanced/unbalanced switch, and the stereo, bridged or tri-mode? Also, what gauge wiring kit do I need and where is a good place to get one?Please help a beginner?
These are my amp specs:

75 watts x 2 at 4 ohm RMS
150 x 2 at 2 ohm RMS
300 watts RMS bridged into 4 ohm
Gold-plated power/ground and speaker connections
Gold plated RCA inputs with extra set of RCA's for adding an amp
Balanced/unbalanced switch for RCA inputs
Infrasonic filter at 25 Hertz eliminates inaudible low frequencies that waste power
High or low pass filter with on/off
Stereo, bridged, or tri-mode capable
Hi-pass filter adjustable from 50-200 Hz
Lo-pass filter adjustable from 50-200 Hz
Input sensitivity (gain control) adjusts from 5-0.2 Mv

The back of my 10" sub says
-4ohms
-500W MAX
-250W NOM
Frequency responsiveness 18HZ - 2.5 kHz
sensitivity 87 dB

does your sub have 2 pos and 2 neg?

If not, run one positive to the outside positive and one negative to the outside negative

It has two pos and two neg

you can get 150 watts out of it

hook up each pos/neg to eac channel
