Yes, you are correct the Nismo or any 370z in particular already attracts peoples attention but if they look through the window and see nothing that is valuable to them I keep myself from paying for a broken window. Not to mention I live in an apartment which is more open to the public at all times. Even though it is a nice area you can never be too safe. Now back to my original question. What amp would be good to run this set up?
