My boyfriend has this car, and I would like to buy him speakers, for the front and back, for Christmas. Problem is, I have no idea about car speakers! I found out online that the back measurements are 6x9, and 4x6 for the front, I can't seem to find the same brand and style of speaker for both sizes, and the closest I have found are bright yellow. Does the color really show once they're in the car? And, what wattage should I pick? I would like speakers close to the ones the car came with because they had amazing bass, they've just gotten worn out. Ah, I feel so lost in this. Thanks SO much for any assistance!!
