cabling help

[markn]

I have a home theater room that is in wall pre-wired with Liberty 14-4c-ex+ cable (4 conductors of 14awg, cl3 ul). The room is 13 x 22 feet and my panel is on one of the 13' walls. This cable goes to front, surround ,and surround back speakers (not atmos wired). The front and surrounds have two wires twisted at the speaker and avr (I guess for a resulting 11 awg combined gauge thickness). The in-wall surround backs have a single conductor for each positive and negative on each speaker. My question is should the wiring be left as is or is it better to simply run 2 conductors to each speaker (and at avr of course)? The runs are probably approximately 10-12' to each front wall plate and about 30' to each surround. I could bi-amp the fronts with the extra wire I suppose, but that topic as many know has met with strongly divergent perspectives. I have an extra pair of unused channels on my Yamaha avr that I could use to bi-amp the fronts, but I have read that it may not result in much difference without truly bi-amping with a separate amp and power supply. So, I just wonder if all 4 conductors should stay together or whether I should just use two 14 awg wires from each 14-4c cable bundle. Any thoughts would be appreciated. I am trying to learn.

I don't think there is a bad answer here. I will say that if I had the ability to truly bi-amp, and had speakers which supported it, I would go ahead and do so.

The reality is that you are extremely unlikely to make things sound worse, and could get a very small bump in listening quality, especially with any two-channel sources.

This is always the bottom line for me: If you get zero audible improvement, then it's not worth quibbling over. If you already have the gear, and you might get a miniscule audio improvement, then go ahead and go for it.

I think you do understand the silliness of the nuances that are possible here. So, this entire discussion is likely to go off topic, or get incredibly nuanced, but I would do it if it were in my home. Just for the concept of perhaps already having cabling separated in the future in case I decide to add an outboard amplifier.

Thank you for your thoughts and feedback. It is already in place. All I would have to do is buy a new 4-port wall plate with posts and a couple additional banana plugs and plug it to listen. Thanks again. Your feedback is appreciated.

Well, if anything, the wires to the surrounds/rear surrounds might be doubled up due the distance involved but might be tempered by the impedance load of the speakers involved, but for the shorter distances it's overkill. I wouldn't bother bi-wiring with an avr altho in your case it's almost already there so like BMXtrix says no real harm, but I wouldn't expect anything nor would I personally bother.
