Hooking up sub

Hi, I'd like to hook up a powered sub (Energy ES8) to an older Technics HT receiver. There is no sub output on reciever. I was told not to use the "B" speaker hookup as this could screw up impedence. I was thinking, could I hook up to tape RCA outputs Get an adaptor that merges the L+R into one RCA cable since normal sub output is mono anyway? If not what would be the best way to do this? The sub is powered and has a volume control and a crossover selector knob. By the way will be using 6 speakers, the front and rear L+R, center and the sub, all Energy speakers.

Thanks,
Tom

If your sub is powered (and it is, right?), then hooking up the the sub via the B speaker hook-up should not affect impedance, the receiver is not "driving" the sub (the sub amp is), the receiver is only sending a high level signal to the sub amp. This is also by many (like the REL sub manufacturer) considered a superior signal transfer.
The person who told you not to do this was probably assuming that the sub was NOT powered by its own amp. Hope this helps,
