I'll admit, I don't believe our vehicles are opportune for kick panels but some vehicles work very well with that application. I'm still trying to figure out a "good" installation for our vehicles. I really don't wanna go through the process of deadening doors n' such.
My a/d/s/ speakers use a 6db slope for the mid so I'm wondering how well they'd work with a tweeter in the A-pillar. I believe the tweeter is a 12db slope.
