Stereo help for 2000 ext cab
 

I have a 2000 F150 ext cab. Im wanting to replace the head unit(1.5 DIN) and the door speakers(6by8), correct me if Im wrong on the size. I want the spekers to have some bang. The head unit can be touch screen or not. So does anyone have any suggestions on what works good and doent cost a ton of money? Thanks for all the help.
