This is my first post here, I just installed rear 3-way Kenwood KFC-C689's
and I now want to work on the fronts. Should I stay with these or use
Infinity Kappa's or something else like JL's?

 

Welcome, out of those you mention, I would go Jl.

 

What year and make of vehicle is the application for? and What type of music do you listen to?

 

Team Deaftraps, it's a 2012 mustang coupe. I listen to classic rock, progressive rock, Jazz
Fusion, and folk. Bob Dylan, Dave Matthews Band, Eagles, My Morning Jacket, Kings of
Leon& Rolling Stones to name a few.

 

JL's would be a good choice.
