my 02 quad cab has the stock speakers i'm guessing. just wanting to know what size they are and some better ones cause mine are all scratchy sounding. nothing to make boom boom just oem style that will last

 

Front doors are 6x9 rear are 6 1/2. If you have the factory Infinity system and you only want to replace the speakers, the 6x9s have a crossover built into them that you will have to remove and glue it to the inside of your door. If you cut it out and don't reuse it your rear speakers and the tweeters in the pillars will not work. I just put Infinity Kappas in mine with an Infinity Kappa 5 amp and dynamated the doors. A little expensive but it does sound great.

One thing to keep in mind is if you get high power speakers (say over 60w) they will not sound good unless you get an amp to bring the power level up close to the max power rating of the speaker.

 

They are 5.25 in the rear but some 6.5 will work.

This may help you

6X9 Front and 5.25 rear. Get a door panel removal tool makes life realy nice.. I know the sizes I just did mine...

I bought sony xplodes since they were rated above 100 watt since I have a 1000 watt amp they sound good, and are 4 way speakers paid 110 for all four at wally world.

 

i got some rockfords in the front doors 6x9s and stockers in rear with a 450 watt amp runnin to tens sounds good!

 

I had some issues with the front door speakers, they can only be so deep otherwise the window will hit it. I ended up going with 6.5" with an adapter plate for the fronts.

 

alrighty, thanks for all the input guys!
