For setting up your speakers in an auto shop, I am going to guess that the gauge of your speaker wire or the connection type that you choose to use will make absolutely no difference as to the quality of your recording. GO with something quick and easy for portable applications, and then maybe the slightly nicer stuff for when you are staying put for a while.
Good idea. I could get some smaller guage stuff to take out with me for tracking. I soldered the ends of the wires and it's alot easier to get them in/out now.
