Two-channel sub connection options

I apologize if this isn’t a very high-end question, but perhaps my ignorance will amuse you.

I recently retired the full-range speakers I’ve been using with my Integrated Amp and replaced them with some smaller speakers which will require a subwoofer. For want of a LFE output on the amp it appears that I’m obliged to run speaker cables from its System B outputs to the High Level inputs on the sub.

Question #1: Does that mean that some substantial fraction of my two-channel amp’s power will be diverted to the sub, bypassing the subwoofer’s own internal amplifier?

Question #2:  If I simply need a two-channel line-level signal for the sub that is subject to the same volume control as my primary speakers, could I not use the headphone jack on the amp (which has no separate volume control) and run a 1/4" Phone Male to Two RCA Male Cable to the sub’s RCA inputs?

If both of these options are possible, which is preferable?

I'm no expert on this, but I believe the high-level signal received by the sub is converted to a low-level signal before being used by the amplification process in the sub's amp.

I run two subs in my two-channel/HT system by running them off the two-channel preamp using siamese connectors. While this is viewed as being wrong by HT aficionados, it works well for me, as my main focus is two-channel listening.

Good luck,
Dan
