Vitop, absolutely do not connect the outputs of two power amps together, or to multiple binding posts on speakers that would in turn connect them together, even if both amps are never on at the same time.
See the following threads, and the other threads and links provided therein. As you’ll see, possible approaches include speaker-level switching devices, and use of a single amp for the front left and right speakers in conjunction with the "home theatre bypass" function that is provided in many preamps and integrated amps.
