And what are the speaker inputs and outputs on the back of the sub for? They are the crimp the wire in the hole style (push the knob down and insert the wire and release). A detailed info would be very helpful...Thank You in advance !!! Thanks Again !
And here's another question....if a blu-ray disc's audio is noted as LPCM 5.1 ( NOT Dolby True HD or DTS Master) or what not..what setting on the receiver do i use or set it at?

I think if the audio on a Blu-ray is LPCM it is automatic, no settings needed.
The easiest way to hook up your sub is to connect the (red/white) RCA inputs on the sub to the sub pre-out on the receiver using these:
"If your home theater receiver has a single mono RCA subwoofer output and your subwoofer has left and right (L/R) RCA inputs, then this product can be used to split the signal to the L/R inputs on the subwoofer without degrading the audio quality."

You can also connect the sub to the receiver using the sub speaker outputs. You would have to connect speaker wire from the left & right front speakers to the matching speaker inputs on the sub. Then connect speaker wire from the sub speaker outputs to the matching speaker binding post on the receiver. Then you would tell your receiver you have a small center, small surrounds,
large left/right fronts & no subwoofer. The manual below explains it in better detail.

OPTION #1—
Receivers that include a “Sub Out” feature—the most common hookup method with
Dolby® Digital receivers.
NOTE: Use either the L or R Line input (another hookup option is to use a Y-split cable
and connect both L and R Line inputs). After you make this Sub Out connection, turn
the "Low Pass" filter fully clockwise.
•Connect all speakers directly to the receiver. When using method #1, adjust
your receiver’s speaker configurations as follows: Set Front, Center and Surround
speakers to “small.”
• Receiver Settings:
• Front, Center, and Surrounds = “SMALL”
• Subwoofer = “ON,” or “YES,” or “PRESENT”
•Set the crossover frequency on the receiver to 120Hz.
OPTION #2—
Two channel or Dolby®Pro Logic receiver with no “Sub Out.”
If you elect to use the speaker level inputs, use two-conductor 16 gauge or thicker
speaker wires. See your Polk dealer for wire recommendations.
Note that one of the speaker input terminals on the rear of the speaker is marked red (+)
and the other black (-). Make certain that you connect the wire from the red (+) terminal
of your receiver to the red (+) terminal on your speaker, and the wire from the black (-)
terminal of the receiver to the black (-) terminal on your speaker. Speaker wire has some
indication (such as color coding, ribbing, or writing) on one of the two conductors to help
maintain consistency. If your subwoofer doesn't seem to produce much bass, it is most
likely that one of the speaker wires is connected backwards. Double check all connec-
tions for correct polarity.
Strip 1/2" (12mm) of insulation from each of the two conductors on both ends to expose
the bare wire. Twist the exposed wire of each conductor to form two un-frayed strands.
•Connect the left and right front speaker outputs of your receiver to the speaker level
inputs of the powered subwoofer using speaker wire.
•Then, connect the left and right front speakers using speaker wire from the speaker
level outputs from the powered subwoofer.
•Connect the Center Channel Speaker directly to the center channel output from your
receiver.
•Connect the Rear Surround Satellites directly to the rear or surround channel outputs
from your receiver.
• Receiver Settings:
• Front speakers = LARGE
• Subwoofer = “OFF” or “NO”
• Center and Surrounds= SMALL
• Crossover Frequency= 120 Hz
