I own a 06' Zx5. But its at home right now and i got a ride to work from my co-worker. But i wanna order some speakers right now online but i have no idea the speaker sizes for my doors. I know that there is only 4 speakers, and i "think" the front door is 5x7, but i am not sure. And i have no idea what the speaker size is for the rear doors. If anyone can tell me, please post here. Thank you for all your help. Mahalo!
