Since the amp has 4ohm and 8ohm taps, can I run two sets of speaker cable using each tap? I want to run a set of cable to my mid/tweeter using the 8ohm tap and another set to my woofer using the 4ohm tap. It so happens those are the respective impedances of my speaker's modules (Von Schweikert VR-4SR). Could that damage the amps or would I be better off running both sets of cables from the same output on the amps? I'm new to bi-wired speakers.

Thanks
