i have a 05 g35 coupe...everything in the car is stock as of now

i recently purchased infinity kappa's 6.5" for the door panels. I am clueless about g35's and the audio because i have always been into civics and they are easy to work on.

My question is, do i need to purchase anything else to install the speakers. Or are they plug-and-play deal?

and do i need speaker spacers or will they fit right into the door panels?

any help will be much appreciated.

 

well other than conencting the speaker wire to the existing wires there and choosing the right polarity they're pretty much plug and play and spacers will eliminate any potential problems hitting the window or getting the wires caught in any moving parts

 

nice thanks a lot
