Currently driving a 2012 Lariat with the 58N Nav/Sony sound system.
I must say I have been plenty happy with the audio in this truck.

Comparing to a 09CTSV, Corvette, 09Tahoe, 14 challenger srt8(harmon Kardon 18 speaker- Very poor)
Currently has the enclosed sub under the rear pass seat.
Did they carry this setup over into the 15 F150?

I did the build you own truck but didn't seem clear. I picked the Sony option. I assume that' would be the comparative.
Thanks

 

for 15 Kicker 8" sub option is available for like $600 or so and comes with a separate amp.
