i was kinda shocked i couldnt make it work, but honestly after buying the 6x9s i couldnt find a single spot in the whole car where i could mount them without cutting into somthing, and in the rear deck im not even sure how the adaptors really work. 4x10s litterly just fit up in there, the 6x9s will not even come close to properly fitting into that area. those adaptors must bring it down about an inch to 2 inchs, and sorta swing it back alittle. as far as going through the top of the package tray, i dont see how thhat would really ever even work, cause the mounting area of the speaker would hit the window, and the rear seat. maybe im wrong but i wasnt and aint cutting into anything like that. i thought about putting them into the wid rear piller trim but in my opinion it would look hacked, and then there was the side panels in the rear i thought about, didnt like the amount cutting that wouuld require either. iim sure theres ways to do it, but iits not for me. ive become very fond of trying to keep things clean and semi factory looking in certain areas, i dont know i have had to many things gor wrong when things get cut up and modified, so brainstormed what i thought would be brilliant actually woke up that morning and it instantly popped into my head, but i just cant see it working and being up to snuff for me.
