Well this is and isn't a fix. I don't know what the underlaying problem is that causes the Amp to shut down but I have come up with a way to stop it from doing so. What ever the problem is it is triggering a circut on the board called "Protect" which can be circumvented. You need to start by pulling out the amplifier unit from the subwoofer assembly. You will see that there are two circut boards at 90 degrees to each other that are connected by 3 sets of connectors. You need to remove the screws and wire that hold in the board attached to the bottom of the assembly. You can then pull it out disconnecting the connectors. The connector closest to the power trasformer is the one that we are concerned with. On the vertically oriented circut board you will find a small map of the connector identifying pin #5 as "Protect". Inside the portion of the connector attached to the bottom board that you pulled out, use a small set of needle nose pliers to break off pin #5. Then reassemble the amp and put the subwoofer back together. I used this solution and it has been working since. If you have reservations about breaking the pin out then try just bending it out of the way and partially reassembling the unit and powering it up. Once you see that it does indeed solve the problem you can break it out. Like I said, I don't know why it started to turn off spontaniously in the first place but this does fix the problem.

SOURCE: jvc th-m45 shut off
shut off audio system is performed to protect it from damage due to high current consumption or short circuit in speakers try to disconnect subwoofer first and check if it is ok. the problem in your subwoofer or its cord-change the cord and check if it is ok thats fine if not change subwoofer.do the previuos for all speaker one by one.
if all above failed you must contact service center for help.

> I need to use the cable remote to change the channel and the TV remote to change volume.
That is because your TV is looking at the output of the cable box (probably on channel 3 or 4) so the TV has to be statically tuned to see the cable box's output.
On the second question; I, and perhaps others, can't answer this without spending a lot of time to download manuals for both systems while you have them (presumably, since they are new) on hand. You didn't include the TV's model number anyhow so even that wouldn't be adequate.
The home theatre may have a receiver but what does it receive? Unless it also has channel capabilities that correspond to cable channels, it can't. The typical routing should be from the cable box to the TV S-video input and the sound can be routed separately from the cable box to either/or both, the home theatre's and also the TV's audio inputs.
When I am installing new stuff, I make a sketch of the routing I want (or have) to use. To me, this is less confusing than the supplied instructions.

Funny enough.... I had this same issue and could not for the life of me figure out what the issue was. I even called a tech out to my house and he was just as confused, called his boss and told him everything that was happening - working fine until a certain "noise level" was reached. The company manager had never heard/seen anything like this before and my house just happened to be in between his work and home so he planned to stop by on his way home. Confusion from us all.... The speaker wires are interchangeable with this system (positive/negative) and when I had moved, still under warranty from where I purchased it from, the company offered to come and re-install everything for me - the ding-dong they sent hooked all positive into the negative and vise-verse. Apparently, the th-c6 can handle this up to a certain point than it shuts itself off to avoid damages??? This is what I was told. Not thinking a electronics tech would install ALL the wires incorrectly this was not something that was first checked, of course. It was noticed as we all three sat around looking very closely at the inputs. It was noticed as we slot by slot checked that the wires were inserted...hmmmm, you think the negative wire in the positive slot has anything to do with it??? LOL, switched them all and worked perfect! Hope this helps.
