This mentality makes as much sense to me as people that will go and spend tons of cash on there setup then get a 4-foot-wide decal proudly proclaiming "Kicker" or "Kenwood" or "Pioneer" or something akin to that across there back window. I'd rather people didn't know I've invested a goodly sum of money in my tunes so the odds of that gear remaining in my ride increase considerably.
If you have the wherewithall (money, space, power, etc) to run four 10s I'd do that in place of two 12s.
