hmm, lets see, my first system that costed $800 got stolen...hmm...oh yea, i ripped off the insurance company for $2800...and yeah, blew it all plus $200 on the replacement system and therefore, have no regrets. (hey, insurance makes a living ripping me off, arent i entitled).
well one regret is that with an expensive system, when 3 JL 12W6's blow out after 2 years, you gotta spend $750 replacing them, whereas i could have replaced my old kicker competitions for like $300. and when my amps finally die, they will cost a lot to replace as well.
