Re: sub and amp problem
You should get power even without the RCA cable.
I believe you should take time and check your connection.
please use the right cable for your sub. you need the right cable
to boost the sub. Check radio shark or Sam Ask for better sub cable.The better one don't come with your system.

ok, temporary cheap fix... (i mean in a ******* engineering kinda way ;-) . . . ) since your primary receiver has a sub-out RCA plug, you can hop into the local pawn shop, buy a cheap receiver and an RCA line splitter, and connect the primary sub-out to the CD or any input EXCEPT phono (resistance is different on the phono rca's). remove the plate from the sub and run the speaker wire from the "pawn stereo" directly to the speaker. replace plate on sub to keep box sealed, and adjust receivers to desired level of bass & volume. You have spent $50 and now have a decent sounding system again.
Yes? Not broken. Redefine the failure mode and start over.
No? Is it defined to the receiver?
Yes? Are you sure the RCA cable is ok? Try another.
Let's prove it's getting an input. Move the cable from the Sub Woofer Out to either channel of the Main Output (below the speaker connectors) and choose FM as the source. This would eliminate direct a Front Channel signal to the sub, bypassing the internal dependency of directing only LFE to the sub. Granted, there may not be much low bass in the program but a working sub will reproduce something in the presence of full-range signal. You may have to actually touch the driver to feel it moving.
Then we're doing forensics.
Did it just stop working while you weren't looking or was there something traumatic that preceded it?
Disconnect the power to the sub. If you can access the actual terminals on the back of the speaker driver you could disconnect them and attach speaker leads from, say, your front right speaker, to see if the driver is alive. Or, if you have an ohmmeter, just measure across the terminals. You should have some kind of low single-digit reading but not a dead short. If the driver is ok that would point to an internal amp problem. Too bad. A pro needs to look at it.
I had a Klipsch sub amp die on me and the local guru couldn't do anything with it so I disconnected driver from the amp, ran some cables outside the enclosure from it and got a separate amp to push it. So it's not a total loss.
Although most of my background is in car audio & acoustics, I did have a thought or two about some tests you can do.
DO THIS AT YOUR OWN RISK OF ELECTROCUTION - Have you tried checking the speaker terminals with a voltmeter while the unit is plugged in? I,ve seen solid state amps (both car & home amps do this) kind of lock up and send constant line voltage to the sub. In some cases the sub snaps instantly, high power subs may not. I've used power from a 110v wall outlet to show off some high SPL systems I've built (very painful 60hz earthquakes). So be careful at the sub terminal it may have some voltage at it.-(If it does you probably know the rest of my answer.)- If so the sub will most likely be wasted and fused voice coils are also common when this happens.
If everything checks out okay there (make sure to check if the subs resistance is at spec while you're there) use the voltmeter and start poking around the audio side of things both on the powered sub and RCA's. You may even find a easy problem on RCA cables. Also can/did you plug the RCA's into a known source, to check their output. Most home audio is 1.5v max but some can go as high as 8v max or so. Also don't be afraid to check the simplest of items like source buttons, specifically the tape monitor buttons. My equipment has these such tape functions with little or no indication as to weather or not they are active, and not being plugged into anything you get no sound. I hope I gave some idea's you may not have tried, your fellow Audiophile-
In general, there are two ways to hook up your sub-woofer. First using the high level outputs from your receiver ( speaker output from the front R & L speaker terminals ) run a set of wires from the outputs to the speaker inputs on the sub-woofer, you do this in concert with the speaker wires going to the front R & L speakers which you then attach to the R & L speaker outputs on the sub woofer amp. Note that the sub woofer doesn't power your front speakers, the connections from the sub amp are just a pass through connection where the signal needed by the sub is parasitically taken from the inputs. Second is via a low level output from your receiver / amp to the low level input on your sub amp. This is normally done via a RCA type of patch cable and connected to the sub woofer RCA jack on the rear of the source receiver or amp, Next run the patch cord to the sub amp an into the RCA jack input. IF you have a right and left input, use the Right input.
telll sterio use sub out and remix on in settings menu on steiro ok also does it have speaker wires in and out use them off fornts ch from sterio then back up throw sub to fronts set cross over on 100 or so
