hey guys anybody use image dynamics ctx65 with stock headunit? how does it sound i don't have bose system. it doesn't say bose on it so i don't have a amp. i was thinking of installing these speakers with a 2 channel amp. on stock headunit. would it be marginal upgrade? or a night and day difference?

 

With a good amp, it'd be more than marginal, but they're coaxial, not even a good set of components, so you've got plenty of room to go up.

 

You should upgrade. My G have bose system and I think that makes a lot differences in sound
