using Velodyne sub in 2-channel setup?


I want to use pure diect mode on Marantz receiver because sound quality is better than stereo. If I run L/R preouts to sub in, then sub out to power amp to speakers using sub x-over, will I lose signal stregth or sound quality? Should my better interconnects be used in front of sub or in front of amp? I was thinking amp.

so if i use high level inputs, the sub will still use the built in amp? I will end up with 2 sets of speaker leads coming out of my power amp? (parallel)
If I use the high level input, will the crossover still filter out low frequency from other speakers?
I finally hooked up the Velodyne using the high level speaker inputs. I had to turn the volume way down on the sub and toy with the crossover a bit. Seems to work well.
Has anyone else noticed that the bass seems less defined hooked up with the high level inputs?
