Worked like a chime!
Crutchfield Customer Review (What's this?)
Mounted under cup holder onto bracket for factory amp. Not loud enough to be heard if wired straight to Metra module. Wired output from module into bypassed factory Bose amp and then output back to Parrot speaker and it works great.
Pros: Small and works well.
Cons: For my application it required some extra work, but the results are worth it.
