I have a 2011 Camaro SS coupe, I currently have 1 JL 12w7 pushed with a slash 1000. I am going to upgrade all the factory speakers. I am going with hertz, I originally was going to stay JL, but everyone seems to like the Hertz more. Ive heard it is best to replace the factory 6x9's with component 6.5's, do you guys agree? If I stay with 6x9 I would go with the Hertz MPX 690.3, otherwise I will switch it with the Hertz MPX 165.3. Thanks in advance for your advice!
