I just got a pair of boston acoustic sr50 component speakers for installation in my 06 hyundai sonata. I will need coaxial speakers in the rear because I dont have a place to mount a tweeter in the rear, and I dont have the money to do any mods. I was wondering what speakers you guys think I should use for the rears? I was considering the boston acoustic sr65's. I am just not sure they will be able to keep up with the sr50's but they do have pretty much the same wattage rating. What do you guys suggest? The speaker size is 6.5.
