Two 4 ohm coils wired in parallel will equal 2 ohms, with that said if you wire both subs in parallel with each other than that load will equal 1 ohm. The reason you are not seeing the proper ohm reading is that it is a coil and your are actually reading impedence and not resistance. Your DVM is meant to read resistance and not impedence. So therefor 3.4 is actually considered 4 and 1.7 is considered 2. I hope I am clear enough, I am not an engineer, but if you were to ask one why then they would have a better explanation
