    2014 F150 w/sony nav and sync please help

    I want to add 2 amps and a lc6i. I called a car audio shop and they told me it is not possible. Is this true? I personally don't think so, then I showed up to another shop and at first he was a little hesitant or unsure but then he said it is possible. The first guy said it's not possible...
