Here's what i got i have all infinity kappa mid including 8" all range kappas in the kicker panels. For my subs I have 2 audiobahn immortals in custom 38hz box tunned for sound quality yet spl. The amps are JBL crown class d's. I eventually will change all subs to JBL gti subs. At this point right now i am in the 157.3db range but still clean.
