The front speakers should be 6.5" and the rear should be 6x9". You will want to make sure you have the correct ohm speakers though. My 2004 impala has 2ohm speakers and my friends has 4ohm speakers. You can put 4 ohm speakers in a 2 ohm system but your sound quality will suffer greatly. Do not put 2 ohm speakers in a 4 ohm system though, that will cause bigger problems.
I have a 2005 ion-3 quad coup and I have 6.5" speakers.
6x8 or 5x7 they are both the same
I'm having the same trouble with the 2004 Impala.
