A year ago, i had all my stereo stuff ripped off. Yesterday, I noticed that all my speakers are plugged in except the far rear speakers(the onese that are behind the back seat). I was wondering why there was no bass coming out . I looked at the speakers and they are an oversized 6.5 and it looks like there is a built in crossover. How do i go about hooking my two rear speakers to my stock head unit. Can i just re wire and run a long wire so that it is connected to the rear door speakers? How do i do this. Thanks

there must be an existing wire already.

you need the pin connector assignment?

 

where is the existing wire at? I notice there are wires, but i dont know which one to use. What is the pin connector assignment?

 

take photo and post it.
