I have a 2004 spcab and i was wanting to install new front and rear speakers (I have factory stereo and will be changing later),I want something that is medium price but will sound good and last long.....Maybe post a site with specs of what speakers for the front and what speakers for the rear?

 

Crutchfield is a god place to look, and check for fit. I ended up using Infinity 6800cs Component speakers for the front, and 6802 cf 2-ways for the back. They both fit easily in place of the factory speakers.
