notice how the OP hasnt said anything back??
i lulz at this post... i was the manager of a best buy install bay for 2 years (like 10 years ago, before geek squad).... and back then, we didnt hire just any idiot off the street to do installs. they had to have their MECP cert, or have it within 60 days.... now that doesnt mean that the guys on the sale floor arent idiots... cuz the vast majority of them are... but most the time, the guys in the install bay know their shit.... atleast when it comes to basic stuff... and that is VERY basic.
maybe next time, you should listen to what someone has to say, and why... instead of thinking you know everything about car audio, cuz your kicker comp 12's are just so loud in that pre-fab... idiot
on a side note... dont think i'm standing up for best buy here guys, cuz i'm not... they RAPE you, plain and simple... just saying, i know from experience, that they dont let just any idiot in the install bay
edit: after reading some of the posts in here, i think alot of guys confuse the sales guys with the install guys... the sales guys are always idiots.... but the install guys most always know what their doing... atleast when it comes to the basics
