People say there are 6 speakers in this Accord, but I can only see 4 speakers ( 2 in front, 2 in back). There are 2 speakers that are mounted in 2 front doors. Those 2 speakers are very small, that's why I dont know they are speakers or not. Anyways, do you think that the 6 speakers in 2012 accord EX are very good or not? I would like to improve the quality of my car's sound. However, I dont know what parts should I improve or what step should I start?
