I'm planning to upgrade my speakers.
It has a problem when I turn on AM radio, I hear static hiss from rear speaker, but I dont notice this hiss when I listen to FM or CD music.
Do you have any idea it's caused by rear speaker, wires, or Nakamichi system?

In addition to this..today I found out my front 4" speakers are not working!!!!I'been driving this car for couple of months and thought it was normal(it wasn't comfortable..) My friend told me that previous owner could have removed it, so I'll find out when I have time.

for speaker choice, any recommendation for brand or model?

Thanks
