Looking to replace a set of oval speakers, one in the 5" size and one 6"x8" with some better quality speakers. This should be a stealth build so all I can really do is coaxial and put a good baffle and ccf on it.
Setup does have a small 12" sealed that sounds quite right for the car, and provides a lot of THUD to the music.
Thought as a creative conversion, a better new set to put in might be having the 12" in the rear for up to 100hz, the 6"x8" coaxial in the rear doors for 63-250hz(500?, 1k, no cross?), and then bring the front to a more crisp sound making an adapter plate for the 5"x7" holes and putting a 4" driver and a 1" tweeter up there.
Would a 4" and a 1" woofer provide clear sounds from the vocals upwards if crossed correctly?
The rear of the vehicle should provide most of the midbass and lows, just don't want the rear to be the ONLY part providing midbass and lows.
Thoughts on if this is a good idea, suggestions, recommendations?
Edit- Also just noticed that if I can fit 3/4 mdf between door and mounting location, I may be able to put a 5.25 component set in the front, would this assure some midbass as well as clearing up the highs?
