Darn livin'loud, that setup looks straight up violent! //content.invisioncic.com/y282845/emoticons/clap.gif.178cba2c538c68e720c727fcb024b19c.gif
I've never heard any SPL vehicles before, in fact the only one I've ever seen in my life belongs to a store in Opelousas called Sonny's (12 l712's walled off in an astrovan). So I'm gonna have to say the loudest daily driver that I've heard goes to my boy Cory who had two MA Audio 1800XL 18's tuned to 30 hz with a Lunar2200 powering each one (2200w rms total). This setup was simply breathtaking (literally), and he had 5 sets of Kove Audio components run by a Lunar100x2 on each (1000wrms for his highs!). Never competed with it though, I'm sure he could have done well. Sold it all now, along with the vehicle, which was a 95 chevy burban.
Second loudest that I've heard is actually mine //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif .
