Add rear speakers?
 

I have a '14 base with sport package. Of course, no rear speakers. I noticed the harness was there so found the tiny Bose speakers cheap and plugged them in.

**NO SOUND**

Is there a jumper or something I need to change on the HU.... or I am a fool to think this would work :-)

-Thanks in advance.

The FSM may have enough details on the sound system for you to figure out what's going on. (I think you will need a different HU that has an amp to drive rear speakers. Or tap off the signal from the front speakers. But too lazy to look it up myself.)

Or wait a few hours and one of the audio guys will probably chime in with the right answer.

No there are no rear speakers in the base model only the bose system. I'd highly advise against adding rear speakers as they are very small and provide IMO nothing to the audio. If anything upgrade your front speakers. The reason you have no sound is there are no speaker wires from that harness going to the front head unit, only to the back where a bose amp would be, also don't add bose speakers to a base model head unit, you could fry the internal amp with the ohms difference.

Thanks guys for helping out a Z noob ;-).

Anyone want a set of bose rears at a good price? 😀

No rear speaker sound
 

I also just got rear speakers installed today in my 2016 base Z. I do have an aftermarket Pioneer HU in place of the stock unit but did not have the BOSE unit. I did have a harness in place for the rear speakers but like yourself, the wiring was either cut or was not provided up to the HU location. I am the 2nd owner & do know the previous owner did have work done as well. The stereo shop tech told me he had to run separate wiring up the Pioneer HU or spend time trying to figure out what was up. I choose the separate wiring solution to help speed up the job. Also, I choose Infinity Reference 4002cfx 4" speakers for the rears & from what I heard, they had a slightly hard time installing them but all is perfect & the panels are fully flush. Last comment is that some like rear speakers for "added fill" and some don't. I am happy to report that the added fill really does help in this car IMHO along with a few other friends who have listened to this latest upgrade. I previously just had two upgraded Pioneer 6 &1/2s in the front doors along with the factory front tweeters hooked up.

I also have a set of rears installed, JL 3.5 2-way and I love the fill they provide. I have Hertz 165 XL up front and a 10" JL sub in a WickedCAS corner box.

Maybe rear speakers are a Black Cherry thing :p

I have the Bose, but have to adjust the fade a bit more to the rear speakers for the fill.
