What are the speaker sizes on the front and rear door? I see that the front door has 3 spots for speakers. So does anyone know the sizes and or what are good speakers to get to upgrade my sound system.

 

The speakers are 6.5 in the front and rear doors. I recomend pioneer d series speakers components up front. best bang for your buck. Then get the coaxial pioneer d series for your rear door. definitely amplify those as well. if your on a budget i would recommend a power pack amp. Cheaper alternative and fairly decent results.
