5.1 Pioneer feeding 3.1 Klipsch Wiring Config question.

[vVSHARKVv]

If a receiver only puts out a true 80x5 wpc @ 8 ohms, and will be mated to (2) bi-wirable Towers, rated @ 150 RMS / 600 Peak.

Would if be safe to use the (4) Front Channel terminals in conjunction with the (4) Rear Channels terminals. To bring their RMS up to 160. So the Towers aren't starving, while the Receiver isn't glowing cherry red from a 3 minute pumbling?

Receivers, in most cases, are not made to have their amp channels bridged like that. Most modern Klipsch speakers are pretty efficient and it's highly unlikely that you will need much more than a few watts to reach obnoxiously loud levels. I would wire one channel to each speaker and not even bother with bi wiring them as it's typically a useless marketing gimmick.
