Okay,let me put it another way.If you use one run of cable to each speaker two 14awg connected together will be equiv. to one 11awg,you have four 14awg which will be equiv. to two 11awg one pos and one neg. conductor,the "star quad" configuration will stay intact.If you only use one run of cable for both speakers, you will have to strip the casing at the first speaker and remove two conductors for that speaker then you have to run the other two conductors to the other speaker.When you unbundle the four conductors, you have essentially negated the "star quad" configuration.If this doesn't matter to you,that's fine but there are many less expensive 4/14 cables available at lots of places.Below is a link to Parts Express,to give you an idea.Good luck.
