To me, it seems easier to just run the wires straight from HU to speaker. Yes, splicing is not hard, but I would have to splice and/or rewire the speaker connectors as they are split into tweeter/woofer and if I ever wanted to go back to stock for resale, I'd have to splice it back. I'd like to keep everything in place to easily go back to stock without modifying over a previous mod.
Trust me... I have googled. If it takes someone 7 hours to run some speaker wire, they got problems in the first place. Took me an hour to do this in my last car with exception of doors. Was extremely nice to sell the car. took everything out and plugged it all back in the way it was. Google returns many more happy campers for those that just rewired.
PS. Your link was for the camaro which is a different system in the first place.
