I would like to finally get started on my sub install in my 2015 IS 250 F-Sport (NON-ML) and now that my PAC SNI-35 Line Out Converter came in, all I need is to figure out which wires to splice into on the factory amp in the trunk.

The Line Out Converter instructions are as follows:

Gray + and Gray - to right speaker output
White + and White - to left speaker output

Now which wire do I need to attach to which from the LOC to the factory amp?

Here is what my amp looks like and what my LOC looks like. Thank you.

 

Bump. Come on guys, nobody knows the answer to this?

 

Search the forums. Its been talked about before.
See if it helps get you started if you understand how to read wiring schematics

I've been searching for weeks and can't find a single solid answer. Most, if not all pictures in the audio threads are gone, and no one seems to be able to say "this wire to this wire". This is frustrating...

 

Here you go.

I might be able to get you a wiring diagram if you can wait until Friday?

 

As long as it's not any of the ones posted above. They are no help. Thank you.

 

Really? I posted a link to a page WITHIN this forum that has all the info you need. If you cannot scroll down read a simple diagram you should not be doing any work on your car.

 

C'mon give him/her a break, not all of us are electrical wizards

 

I've successfully done amp/speaker installs in several cars and not ever had to go through pages of schematics like that, and that's besides the fact that my amp wires don't look like the ones posted. Thanks for the help though.

 

The wiring diagram that brendanf posted is correct, you're going to be looking at that top connector, the wires for the left side speaker are white (+) pin #12, pink (-) pin #27. Right side are beige or light brown (+) pin #13 and pink (-) pin#28. Good luck!

 

Thank you!

 

So does this mean I will be tapping into the front speaker signals for a mono amp subwoofer?

Maybe that's what was throwing me off, I thought I was supposed to tap the LOC into the stock subwoofer signals?

 

After 7 hours installing, I'm getting no sound from the subs. Amp fires up just fine though. Tried reversing RCA cables, Reversing Amp to Sub speaker wires, no luck...

Edit: Getting sound from subs now but they are VERY weak and cut out at low frequencies. Plus I messed up the wires going from my factory amp to the front speakers and now they sound like ****... I'm guessing I was supposed to tap into the factory sub wires... -.-

 

Ended up removing the LOC from the wires posted above... Tried tapping the LOC into the subwoofer wires... Now I have no sound whatsoever in my car... Volume **** does nothing. Fml.
