Rear speakers 2003 setup help
 

I got the rear speaker cubby recently but it did not come with the cable to connect it to the stereo. I am a complete newbie when it comes to sound wiring so any help as to what options are available would be greatly appreciated (The car is a 2003 with only the dash speakers and still has OEM stereo, have searched for the oem connection but to advail)

You seem to already have gotten an answer here ?

I have a writeup I did let me see if I can find it.

I designed some mounts & 3d printed them for speakers. Had a kit at one time I was going to put together for a diy solution that was everything but the speakers.

Looks like I never finished the doc. Here it is, but it isn't very polished.

The brackets are ones that I designed and 3D print. Let me know if you want a pair. I have a kit that is everything but the speaker wire 7 wire wrap (brackets, speaker cloth, quick disconnects, spade connectors).
