I have a pioneer head unit with 4x6 pioneer 2 ways in the dash, and 6.5 pioneer 3 ways in the bose box in the back. It's time for a speaker upgrade, any suggestions?
Thanks

Need to be more specific. How high end do you want to go? How much do you want to spend? Do you want components that will fit in their stock locations?

I want to buy or make kick panels with 5.25 components for the front. For the rears should I use the bose box or put the speakers behind the sail panels? I'm considering getting a 4 channel amp, so I want to go with quality speakers.
