I want to run this flat wire https://www.amazon.com/gp/product/B00WITWKNG/ref=ox_sc_mini_detail?ie=UTF8&psc=1&smid=ATVPDKIKX0DER on my baseboards to 2 sony core sscs5's and wanted to know if it will be good enough for signal strength or do I have to stick with 14 gauge. If I got with 14 gauge its not flat wire and it won't do 90 degree turns which is my problem here.
