Hey all, i couldnt really find anything that answered my question fully.

I know the removal process for the rear trim, to replace them. I am putting Alpine 6x9s in the rear.

But for the front i am looking at Kenwood 3way speakers, 6.5inch and will come with the 6.75 adapter bracket.

I just wanna make sure that ill be okay getting 3way speakers. Also all the speakers i have / are getting are a 4ohm impedance. That wont be an issue either correct? because if i remember i read that the 2004 Infinity system is 4ohm
