2003 "Premium" audio system specs?
I have a 2003 with the "Premium" Mach MP3 single disc head unit. I have swapped that out for a JVC head, but I'm wondering if the speakers that come stock with this system are good speakers, or if the sound would be much improved with 2 new pair of $70+/- Infinity or Kenwood speakers? It sounds good to me, but would new speakers make a big difference? I know that they are easy to swap out.
Basically, what speakers are in my truck, and are they worth keeping? Also, are they 5x7's?
