Hello, I'm trying to install my Soundqubed 12's and my Soundqubed 1200.2 amp but I'm not sure how to hook up my line out converter. I can't figure out which wires hook up to my stock wires in the trunk? I'll post a pic of it.

You need to start out by identifying which of the three types of
sound systems you have this has nothing to do with which head
unit you have.

How would I figure that out

Base has no tweeters in front doors.
Hifi has extra speakers I believe
Logic 7 will have equaliser settings within sound on head unit.

The Technic Harness is the best way to do this.
Being that you have an 09 US car you will either
have Hi Fi or Logic 7

I'd love to just splice the wires together and be done with it but I'm not sure which wire's to splice. Do i HAVE to use the Technic harness? I have the hifi system.

[TRAVii199]

Okay I found what I was looking for but which speakers would I want to splice into? Also what would I do with the Blue wire on that LOC

You are better of buying a Technic Add a sub Harness
no splicing or brain required.
