what speakers will fit into the doors of my 2 door GMC Sierra?

[Matt]

I'm wondering what size speakers will fit into the doors of my 2 door truck and if it will be enough. Also if a subwoofer is really necessary?

I'm not sure if all years have the same diameter speaker. I know if you go to best buy' website you can look up your year and model under 'car audio'. That should tell you what speaker size you're truck is.
