Go to www.nexxon.com free shipping and you get a warranty with them. You will need to make a spacer or you window will hit the speaker or the speaker will hit the back of the door. Not a big deal, but know that you will have to do that. They do sound great, and who the **** runs the components without an amp? What is the point, especially a set with a huge ass magnet like that?

As for the highs, you can tweak the system once you get them in and lower the frequencies to your taste (there are a few ways to do this).

My $.02

Nexxon prie 179 shpped, but this is with a 1 year warranty through nexxon. It is up to you, I have dealt with Ikesound and they are ok too. good luck.
