Hello. I have a 2004 F150 XL Reg Cab. I want to replace the factory speakers and I'm looking at the Polk db571. My questions are: are both the front and back 6"x8", as Crutchfield only says those (6x8) fit in the front? Further, it seems like I hear more from the rear than the front with the position of my seat. Would it be best to do the front or rear set first (only can afford one set right now).

Thanks! Greg

 

It shouldnt matter as long as you have the tunes balanced..IE front vs back right vs left..internal feature inside the unit to place proper power to location of speakers

 

Is this with stock radio? No amp?

 

Yes, stock 6 disc changer. Thanks- Greg
