Couldn't agree more, why replace your speakers and leave inferior wires? Seems silly and "limiting". Rule of thumb, never do speakers with stock wiring. 14gauge is the industry standard when replacing speakers, anything less and you will be limiting how clean your signal is and how many watts your system can handle safely. Of course this is if you are installing an amp, if you are just running new speakers and a stock deck or speakers and an aftermarket deck, you can get away with it because most decks don't push to much more than stock. If you are doing an amp, deck and speakers 110% do 14 gauge wires.
