Look man, everyone's trying to save you some time, effort, and frustration.
Unless the 'high end" stereos you heard were installed like this:
then brand names, price, reviews, and reputation don't mean jack shit
you don't buy nice speakers, and instantly have them sound great
it's no different than buying a $1600 solo-x and being disappointed that it barely made sound because you didn't put it in a box, or put it in a piece of shit box.
Just because replacement door speakers magically fit in the stock speaker locations does NOT mean that's the proper way to install speakers, do you honestly think that your car manufacturer really cared how great the factory speakers sounded?
So before you keep running your mouth about the high end systems you've heard, and how you can't make a front-stage supply full sound by itself, reconsider who you're arguing with, some of these guys aren't just "the guys in your neighborhood" or the "locals" that boom bass at kmart on friday night, and talk on their cell phones.
unless you know for a fact that your friends know what they're doing when it comes to PROPER installation, then you haven't heard shit.
2 half ***-installed pairs of speakers are not, i repeat are NOT, a replacement for one properly installed set.
You can waste your time and money if you want, but when your system sounds like compelte ****ing ***, you can thank your bullshit artist friends, and go shoot the shit about your sweet midbass rear fill to the dudes at best buy. but these guys are (read:were) trying to help you.
