I have a Yamaha subwoofer yst- sw005. How do I connect this to my mobile or tv. Does it work without an amp or receiver?

It's an amplified subwoofer. You have two inputs. Right and Left. If you plug in speakers into the output jacks, you can get a 1/8 inch to RCA and plug in a mobile device and the subwoofer's amp will power the speakers and sub.

To hook it up to a TV, the TV has to have audio outputs (White and red, usually paired with a yellow RCA jack. labeled Audio/Video out)

How do I connect the YST-SW45 sub to a different system

It's a standard non-proprietary standalone self-powered sub that accepts any input one could want. Your unnamed electronics will be the determining factor. Manuals spell it all out.

No sound from my Yamaha YST-SW315 subwoofer. When I run the test speakers don't have sound either. Not sure if its the subwoofer or the Yamaha RX-V450 receiver

Feed it with an RCA cable any other audio device you may have (CD, TV, MP3 player, PC) to prove it can or can not woof. It will respond to any audio, not just LFE or subwoofer audio.

How do i hook up sub from main unit.from main unit only has one plug that says sub in.and my sub has two plugs that say L mono and R in. like R.C.A connects.please help

Get a cable that splits a single rca cable into two. It has a female end and two male ends. That way you can feed both inputs from the single sub output on the receiver.

Yamaha does it work ??

I have a YST-MS30 myself. Judging by Yamaha's site, the MS50 looks like it's built pretty much the same way. The subwoofer by itself is pretty useless. The power switch and volume controls are built into the right satellite speaker. There is a level control for the subwoofer, but overall system volume is controlled by the satellite speaker. You also need the power supply (15 volts, 1.2 amps for the MS30, but probably different ratings for the MS50 with its higher power).

Actually, it would be possible to open the subwoofer and puzzle out which pins in the connector you would need to jumper together to turn it on, and you might be able to find a suitable power supply. But it seems like more trouble than it's worth. Complete new system with comparable specs are around $100 from online vendors.

Y adapter to speaker subwoofer

Well, I solved the problem this way, after having gone into a loop of discussionwith "bunnydog." I took the cable set back to the retailer and then I trashed the subwoofer. Problem solved. I have no further need of your assistance.
