Hello,
I just bought a factory sub for my wifes 04.5 lariat screw. It had the wiring for the sub there already so I plugged it in and nothing. Do I need the audiophile head unit or is there something I'm missing. Please let me know.
Thanks in advance,
Darrell

 

yup you need the audiophile head unit too

 

Thanks for the reply. I was afraid of that.
