It is what it is....
Anyone can sit in front of a computer all day, researching speaker designs, quality, technical specs and many other things to baffle a salesman, then in the end what do you have? A baffled salesman and a ****ty sounding stereo system. Mine, Your's, His, anyone's stereo system is only going to sound as good as they can hear. Obvisously no one is going to buy and instal a system that sounds good to someone else.
Again, the OP should get in other peoples rides, listen to what they have, make his own sound decision on what he likes, test stuff out, make his own choice. I love the sound of my speakers, they give me deep and mid bass levels and the stock bose sounds great when powered by an aftermarket amp or stock. To me, my setup sounds great and has tremendous bass. To you, it may sound like ****, it may seem wierd to have to 12's and a 15, but fact is, i'm not here to impress you or make sure it sounds good to you or to what you think is right, what counts is my opinion. Sorry you don't like my setup, have a good one.
