how to wire in aftermarlet amp '09 expedition
 

how would I wire in an aftermarket amp to my 09 expedition limited max, I want to run the jl stealthbox and I'm pretty sure it isn't amplified. I have the stock nav head unit, I would really like to retain the stock look.

thanks

Just off the top of my head, I'd check with Crutchfield - they usually have adapting harnesses for just about everything.
