Where is the factory subwoofer on a 2002 fx4 model with the 5.4l been thibking about upgrading it not much for the loyd thump but if I can replace it with something a little better that would be awesome

 

I don't think they have a subwoofer just two speakers in front and 2 in back I have an 02 fx4 as well and have never seen one with a factory sub

 

You can upgrade your factory speakers with better ones I would say to go threw cruchfield they make it easy for the ones that will fit

 

That's a good idea /\ I did it to my truck and it made a huge difference !

 

What size can you tell me gor the front and tge rear

 

Front is 6x8 and back is 6x8 pretty sure it's been a few years though you can also make 6x9s fit which is a little easier of a size to get a deal on ; )

 

Okay would it just be easier to get 6x9 some people also tell me 5x7 how do the door panela cone off on my truck just pop off

 

For the most part yes I believe there is 1 screw behind the little panel that's behind your inside door handle

 

And the fronts slide up then out

 

the pillar pannel on the back side of the door that is attached to the door pops off, then pop the cover that is around the door handel off, then take the map light cover off and pull the bulb out, then pop the power windows/lock pannel off (pop it at the front and pull it out torwards front of the truck) then undo the connections on back of that pannel, then there are 2 screws, one by the door handel and one up by the pillar. then just lift up and undo the light socket from the back of the map light and your done.

my recomendation for speakers would have to be the 5x7/6x8 alpine type s. they're not extremely cheap, but they aren't over priced either, and the sound quality is TOP NOTCH. they are very clear, and if you ever decide to do a serious sound system, they can handle enough power to run a small amp to them and really tune'em in.
