just connect your subwoofer mono RCA to your amp sub single out rca connector. you do not need to megre all those 4terminals into one. in fact internal circuit of those 4rca are merging inside to one since the sub uses only a single amp. 4inputs was meant for sources with multiple sub out

What you will need is a phono pre-amp, then you can run into the receiver with a line level input to an empty audio input on the receiver, you can try Radio Shack to obtain one.

I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!

Since you're using a standard mini jack to double RCA cable, it's safe to assume you'll be sending line level signal into your reciever, so i think any of these audio inputs will do: AUX, CD, DVD, MD, TV.
Also try the inputs on the front of the unit (i guess they are meant to be used with a video camera or similar but they are designed for line level signals so it should be ok if you decide to use them).
Anyway, keep the source signal at a moderate
level when you test any of the inputs and raise it to a suitable level after you're sure it is coming thru well.
Normally, the AUX input is suitable for any AUXilliary signal source that puts out a line level signal, but if it is already being used, you may use other free inputs.
If you use TAPE or PHONO inputs, you should keep the signal level from the source a bit lower since these inputs will amplify the signal a bit more (especially the phono input which works with signals that are lower in level than the line signal).
I hope this helps.

I have the same receiver... You can try pressing the Option button and choosing Signal Info to see what audio signal the receiver sees and if that changes over time. Maybe the cable box is not outputting according to specifications... TV can live with that, but receiver maybe can't.
You can also try to connect the cable box via SPDIF cable (optical or coax) to see if it helps or not.
