Run 2 RCA cables from the two Purple connections on your Receiver (Labled "PRE OUT SUBWOOFER") to the Red and White connectors on the back of your Sub (it does not matter which Purple connecter you plug into either the Red and White)
Set the volume control on the Sub to about 75%, and keep the power switch in the "ON AUTO" position. To set the Low Pass value, look at the back of one of the front speakers in your setup, and note its frequency range (will look something like 100Hz - 17kHz). Set the Low Pass at a value slightly higher than the low value on the back of your surround speakers.
To set the phase switch, stand in the middle of the room with some music on (something with some bass, but not over the top bass) and have someone switch between 0 Deg and 180 Deg. Listen for which setting sounds "Louder and Fuller". This is the one you want. You will need to do this each time you move the Sub, as its position may change its phase in relation to the rest of your system.

You don't name the electronics, which can be the source of the problem. See #3.
1. If you suspect the cable why don't you just swap in another RCA cable? BTW: there's no such thing as a "subwoofer" cable. Monster makes their money on those beliefs. Cables don't wear out but they can go bad if one or more conductors fails. Oxides devolp at either end which can inhibit conductivity. Remove each end and reinsert it with a twisting motion.
2. Maybe. You need to ensure the sub is defined. Run speaker level check. If no sound at the sub, prove the LFE/sub channel has output by running the RCA cable to a recorder or your TV (low volume). If there's no signal, duh, no speaker will work with it.
3. Mmm, not if it's exhibiting the same problem as the old one and the Polk 450. Have you looked at the setting of the Standby/Auto/On Switch? And the Power Mode LED's? Red is bad.
