Hey I am gettin a new system in my F-150. Tell me if I should change any of these components. Pioneer DEH-9300 deck, Rockford Fosgate 400.4 (speaker amp), Speakers still undicided but most likly Cerwin Vega HED-1685's front and rear, Rockford Fosgate 1000.1 (sub amp), and two Infinity Kappa Perfect 10.1's.

any advice or comments are appreatiated

 

Not for sure on most of the stuff you listed wehter it's good or bad. I did hear that the OEL display on the Pioneer's has been known to fade out over about a years time or with a lot of direct sunlight. Not a proven point but a good one to think about when investing 500+ in a HU. Also when Infinity first came out with their Kappa subs (green cone) I had two sets and both cracked. I doubt if they are still like this but in the begining they were. I have heard that they make awesome regular speakers (5x7's, 6x9's, etc).
