This is cool. Seeing your pillars makes me want to chop up mine and put my HAT L4's up there.
How do you like the that 3.sixty.3 as compared the the MS-8? I've been contemplating redoing my entire setup and not sure what I want to try next for tuning.
My STi sits like this:
Stock Nav H/U,
HAT L1R2's 90deg off axis in stock sails location.
Hat L4's in kick pods
Hat L6's Stock door location.
2 Dayton HO 10's in a 1.3cu 30hz ported box
Alpine PDX 4.100 - runs the tweets and mid ranges
Alpine PDx 4.100 - Bridged and runs the L6's
Alpine M12 for the subs.
Wouldn't mind getting my hands on some Mosconi/Zapco/Audison products myself lol.
