Audiophile system and PIE
 

2004 F150 Lariat

I have the audiophile system with the sub and amp. I would like to add a bluetooth P.I.E. but it says it won't work with premium amplified systems. Is this what they are talking about?

Has anyone hooked one of these up (or one of the other adapters)? I know how to pull the head and everything, but I want to make sure it will work with my setup before going through the work.

Wonder if it's possible to hook more than one of these up, like amp output AND bluetooth.

How to install a pioneer avic z3 audiophile subwoofer to my 2005 ford f-150?
