rear speakers

[spidey10]

i noticed that on my 08 altima(2.5s sedan) that there is the ability to have 8 speakers. 2 tweeters on dash 2 in front doors 2 in back doors n 2 near trunk. the 2 rear doors do not have any in them i believe but i would like to put some in but i do not know if their are wires or anything lready runing there and i was just seeing if anyone had already done this before and knows whats up any feedback would be awesome thanks!!!!!

If u're planning on just adding speaker to rear door holes and keeping everything else stock - don't even bother.

If u wanna replace your headunit and all of the speakers, get an amp or 2, sub then.... well, it depends on what kind of set up u wanna do.

I have 8'' dedicated midbass speakers that i'm gonna install in rear doors but also have component speakers in the front and sub in the trunk. No speakers in rear deck at all so there;s more space for sub's bass to enter the cabin. Adding DEDICATED MIDBASS ONLY to the rear doors makes sence in this kind of set-up.

FYI - unless u have factory BOSS system your rear doors are not prewired.Also, from what i know there are 6.5'' holes in rear doors so your speakers have to be 6.5 or smaller (with correct adaptor) if u don't wanna cut your door to make that hole bigger.

Hope it helps.
