Upgrade of speaker wires

I want to install my new system of all new JL Audio component 6.5s for the front, 6x9s for the rear, and a 10w3 v3 sub in the trunk and I noticed how thin the factory speaker wires are. Since I will need to rip apart the interior of my 96 Accord EX sedan anyways how easy would it be to install new thicker gauge wires and would it be worth it?

definetly worth it. I used a coat hanger to pull the wire through the dash to get it into the front doors. back is easy.
