718? in front? oh bera gharak!
for any speaker to perform anywhere in the car, the front and rear of the speakers must be isolated from each other. if they are not isolated properly, the front and back wave from speakers will cancel each other and sound quality will go down.
so keeping that in mind, any speaker can be installed in the front door panels ( i have seen people put 10-12" subs/mid bass drivers in front doors) as long as the above mentioned is taken care of. doing this aesthetically is a different matter altogether. it all depends on how much u are willing to spend who is making the panels for u
