Go to http://www.crutchfield.com and click on What Fits My Car?  Type in the information and it'll tell you what the sizes are.That's my opinion. Take it, leave it, or correct me.

His back speakers were 4x6's that I replaced with some blaupunkts and his fronts were 6.5's with seperate tweets that I replaced with a polk momo component set. Sounds sweet.

I just purchased the polk momo 6.5's for the front doors of my 04 crew cab.  I plan on doing the install myself and was wondering how to mount the tweeters.  Also is stock speaker wire ok or do i need to attempt to run new through the doors?  Thank you.

you have a lot of options since u have a 2001... you can get a stealth box from jl audio which sound great but can be expensive.. there is mtx thunderforms.. which im not a fan of but in the dodge trucks they sound great.. q logic also has boxes... but if you want somthing totally customized.. you should be able to raise the back seat by adding spacers where the seat mounts to the cab at and you can have a box fiberglassed... i've seen a box for 4 12inch w6 jl's under the back seat.... i would check http://mobile.jlaudio.com/products_stealthbox_pages.php?page_id=168  and there gallery to get ideas.. heres the truck i was talking about http://mobile.jlaudio.com/gallery/detail.php?vehicle_id=649 alot of it depends on how much you want to spend on a system because you could do a cut threw  also which is a lil more money but gives you lots more choices for subs and box size...S.O.B custsoms..

Front speakers are oversize 6.5", rear speakers IIRC are 4x6". The MTX Thunderform for this vehicle actually sounds and performs really really good.Top Secret, I can tell you but then my wife will kill me.
