Yep it's true. Bose systems are a PITA. A plug and play harness will not work. Your Alpine will work in the SS but you just have to either tap into the factory wires after the Bose amp or run new wires from the HU to each speaker. It is mot very hard to do it is just time consuming. If someone on here knows what color wires are what it will make tapping into the factory wires alot easier.
