I have a 2011 FX4 Crew Cab, with Sony Navigation and sub-woofer. Has anyone installed a system with this equipment? The stock system just is not enough for my taste. If I got the super crew sound box for the back seat what would I do with the old wires that went to the stock box? Also what would be the best set up for the super crew sound box? 1-12, 2-10’s, 2-12’s?
Thanks for any help
