Can I splice different gauge wire together?

I have about 120 feet of 12 AWG running from my Denon out to my back porch, everything has been drywalled over, I now want to move the speakers about 10 feet farther away so they broadcast more into the back yard vs the porch and all I have laying around is 14 AWG. My question is can I just splice (I plan on using a waterproof wire nut) 10 feet of 14 AWG get the the length or should I spend the $ and buy another spool of 12 AWG and splice that in?
