I was installing my head unit today and ran into an issue. Non-Bose system. (Kenwood kdc-152) I dont have sound coming from the rear speakers, only the front. ( no speaker in rear doors or in rear deck) I think its because the rears are amped right? How do I connect that amp to Head unit so the rear speaker will work too?

Metra 70-1787 (met-701787) Wiring Harness for Select 1996-2008

https://www.audiforums.com/forum/b5-...0/#post1314628

 

Thats not the one sonic electonics gave me. Also my radio only has 2 rca outputs and i need that for my sub. Where do the 4 rcas go to? I guess ill have to buy that.

 

And that says for bose and i have non bose.

edit:

Nevermind I have non-bose on crutchfield and it says thats the wiring harness I need. I guess sonic electronix are just unaware. However, I still dont know where those rca connectors go to for this product : http://www.sonicelectronix.com/item_...a-70-1787.html . I only have the two on my new radio (Red and White [R and L]) for a subwoofer amp connection. That adapter in the link has 4 (Black, White, Purple, Light blue) that are supposed to connect to my new radios "Pre-Amp output" Please help.

 

You could use a series of Y-splitters to allow connection of a sub amp and the pre-amp harness - its all line-level signal so it'll work fine with no degradation.

 

Ok. So i should buy like 4 y splitters? Im still confused on the placement of the rcas though. Does it matter where i put the 4? Theyre sll different colors than the two on the back of the head unit.

 

Like these? : http://item.mobileweb.ebay.com/viewi...id=93799079621 . Although i do think it will get a bit crowded behind head unit stackin these on to get 6 rca female connectors out of 2.

 

It definitely will but with a head unit that only has two preouts it's pretty much your only option. You may not have fader control that way either.

 

Aww well we'll see how it works wen they come in the mail.
