Powered Subwoofer connected to integrated amp's speaker outs?


I'm interested in purchasing a REL T/7i which is a powered subwoofer. I have an older Marantz PM7000 integrated amplifier which has no explicit subwoofer outs. REL has a tutorial about hooking up their powered subwoofers to the amp from the speaker outs on the amp to the high-level input on the sub. This is all very straightforward and simple. What is not clear, however, is if there will be any power demands on the amp. My guess is no, since the T/7i has its own amplifier. I would like all the power from the PM7000 to be available to the KEF LS50 Metas that I'll have hooked to the other speaker outs. Can someone please address my concerns? Thank you.

Thanks to all who have replied to my posting! I really appreciate it. It appears that I won't have a problem at all with my desired setup.
Update: I had emailed REL with my concern and this was their response:

The High Level input on all of our subwoofers has an impedance of approximately 150,000 ohms, compared to the 4-8 ohm impedance of most loudspeakers. As a result, when a REL subwoofer is connected using it's High Level input it will not place any additional current load on the amplifier, or draw any amplifier power away from your main loudspeakers.

Their response reiterates what everyone here has mentioned. Again, thanks to all who have replied.
