I am going to try and install my amp/subs in my 05 TL today, and want to know what everyone uses part wise to tap into the factory wiring. I know what to tap into, but do not know the best way to do it. I know there are those twist caps you can use to couple multiple wires, as well as the color ones where you clamp the middle after inserting the wires, etc. Whats the best to use? Any help would be appreciated.
