Things I have learned about the Z.

The bose system "if you have not got the car yet do not get the bose" is a PITA to upgrade. You can upgrade the sub and speakers but the bose amp and all will still fade out the bass and highs when you turn up the volume "how it was made" Also yes a lot of shops and including me will charge you more for upgrading a bose system because there is just so much more you have to worry about and do. If you want to put a new amp and keep the stock bose head unit you have to use a jl clean sweep to clean the signal than send it to the am that is an extra 200-300 bucks just for the part. I can go into even more details if you would like. But they are not worth the money save it an get a nice aftermarket setup. The thread you made asking why they are hated holds a lot of the info. I put a few good paragraphs in there explaining it all.
