I have a Koss 6.1 setup and on mine the dvd player and I guess it would be called the amp are built into one. So all my speaker connections are made to one large unit. I was wanting to hook up two bass shakers and I searched and it said I had to have an LFE output. Now I looked at the back of it and I got the speaker connections for the subwoofer and then I have one purple jack that says "active subwoofer out" Now I'm gonna use two of the auror bass shakers (25 watts a peice) and then one of their 50 watt plate amps. How exactly is the plate amp going to hook up to my unit?
