Do these have to be set up with line of sight? Will it work for my rear subs behind the couch?

I put behind a couch. And it works great

Can this be used for surrounds ? Do you have to buy 2 kits ?

The WSK-100 is only meant for Subwoofers since it only has an RCA mono input/output but the WRSK-250 can be used for either a 2.1 set up or rear surround set up.

Can you connect connect multiple subwoofer with additional receivers?

Yes, you can connect multiple recievers to the WSK-100 or WRSK-250 for multiple sub woofers and multiple speakers/sub with the WRSK-250.

Can you 'mix' a Front speaker and a rear surround sound speaker with this device?

Depends are you gonna connectThe front speaker Your technology might be messed up if you do that connection that’s happened to one of my friends he plugged in the wrong thing and then from there on a repairman had to come just me it’s not like it will happen to you don’t worry about it
