Replacement Speakers
 

I am looking to replace all of my car speakers so far I am looking at the JVC Arsenal CS-ARS500. Can anyone let me know if these are good speakers these will go in the front doors and tweeter will replace my pillar speakers. I do not know what will go behind my seats yet.

If anyone wants to share what they have maybe I can compare and take something else for the front and back.

Thanks in Advance

Edit:
I have the stock Bose unit without Navigation, I have not decided if I am going to switch out the head unit, I like my bluetooth, xm sat and my steering wheel controls. I know that you can get a box to program all that but I have heard pretty bad things and other Z owners that could not get everything to work properly. SO for now I will just replace speakers.

if you ave boise you will need to replace amps too

Yes you will need a amp and a re-q5 in order to run the new amp. Reason? Simply put the bose amp is made to run bose speakers not aftermarket ones.
