I have a 2003 F150 with 6x8 door speakers. I currently have JBL GTO that are about 15 years old and wanting something new. Not connected to an amp just Pioneer 4500NEX. What is a good set for around $100 a pair ill be doing front and rear. Heard good things about Rockford Fosgate but open to any brand. Just looking for decent upgrade from my current speakers. Thanks for any help.
