Hi there, I have a similar question, but I already bougth the integrated amp, Marantz PM7005, which doesn't have a sub out, so I had to connect it to my SVS SB1000 using the same wiring that are going to the speakers. Do you think that I'm going to do any harm to any of the components? Am I doubling the bass notes even though I'm x overing at 80 Hz. Do they cancel each other? Thanks for your time and comments
