Stock Elec. in 08 Ford F-150

I've seen a lot of threads on this subject and I hate to beat a dead horse, but...

I'm thinking of putting a system in my truck. I am trying to keep things as simple as possible by running a JBL GTO 5355 5 channel amp for two sets of speaks and a sub. Should run somewhere in the 500-600 watt rms area at 4ohms. Is the factory battery, alternator etc sufficient to run this amp cleanly? Thanks!!!!
