Now building my audio setup

As a drop in replacement for stockers....no. Not sure if OP is willing to go that far in order to gain a little more on the bottom end, when he could simply get the larger drivers in the first place.

Heck, I've built a complete Pyramid system back in the day for an exercise in installation. Sounded pretty damn good for the amount of money in it. BUT, what it took to get it there install wise, was another story.

In this case we are just looking at a simple upgrade over stock for a cleaner, better sound. Getting the results from smaller drivers is more involved than a simple drop in and go deal.

 

to the OP. if you're interested i have a brand new set of the eclipse 6x9 components and baffles made by mr marv. he got my wheels turning so i'm going 3 way active(hopefully) and i may part with this set up. these speakers were recommended by marv and the build quality is pretty good. pm me if you're interested. these pieces alone will take care of your front doors, and will sound good doing it.
