bought 1 component set, stuck with it since early 2009 until this very day.
gotten many compliments from many TTs /auditioning and to my surprise i actually got pm asking if i wanna sell it (i think they're better off buying "new old stock" at a discount from whoever that's still keeping lol)

but yeah, my door was sound proofed by EA, dunno how many layers however from observation it seems to be ~2+ layer at the correct/proper places

i supposed i am fortunate to have damn good sifu howiechoo from LYN ICE forum guiding me to the right path
most of them no longer post there unfortunately

and no it's not how the car speakers isn't facing you directly, it's more towards how close the car speakers are as opposed to pc speakers or HT/hifi speakers; simply put - you're not sitting directly in front of the speakers

i still have the creative g500, 8inch front firing subwoofer driver btw, built in amp fried after 7ish years
it's under repair and hopefully it's repairable hehe.
