Added subwoofer via LOC in 2017 2.4

Hey everyone. Just got a 2017 LT 2.4 about a month ago, and I'm ready to add in my subwoofer. I had a 2015 Malibu LT before, which had the same infotainment unit in it, with sub in question spliced in via LOC.

My question is where is the best spot to splice in my LOC, and what are the wire colors? I was able to pull out the infotainment unit and noticed two plugs. One with pink/purple/tan/white(maybe?)/green/black/red wires, and the other plug was just blue. Should I be going for one of these wires, or is there another spot to work from?

Thanks in advance!

Re: Added subwoofer via LOC in 2017 2.4

I'm in the hunt too for the speaker wire colors.

Unfortunately, not much info on the '16's and newer models

Apparently, they changed wire codes and the info on here doesn't correspond

I plan on pulling the door panels off this weekend so I can check the wire colors when I install the bazooka bass tube in the family nox.

But to answer your question, because the Bluetooth and the ANC use the front speakers, I would tap the LOC into the rear speakers. Once we figure out the color codes - you can access them in the vehicle B pillar

Word. I read somewhere to access the sub wires and tap into those? I also read the sub that comes in the Nox acts as a road-noise canceler.

Yeah the factory sub in the 4cyl is for ANC - not music. Which means it doesn't carry any audio signal. Tapping into these wires won't work.

Previous years - you can simply swap the factory amps to activate the sub - but again, not sure if it'll work on the "16+ models.

Re: Added subwoofer via LOC in 2017 2.4

The simplest thing to do is pull the panel off each of the rear doors and find the wire color connected to the rear door speakers. Those wires, in turn, feed into a harness you can find under the front door sill covers that also are easily removed.
You wouldn't even have to pull the rear door panels completely off. Just remove the necessary few bolts near and under the arm rest and start pulling the lower rear door corner.

There is a thread here on how to remove the rear door panels. There are not as complicated as the front door panels. Espeacilly the front driver door panel.

Hmmmmm, now I'm wondering if I should just replace the stock speakers and give up the sub.

So I pulled off the left rear door panel

Wire colors are brown (+) and yellow (-) at the speaker on my 2017 Equinox 4cyl.

Tapped in to those wires at the column and the amplified bass tube works great now.

Looking further on line / colors at the amp should (or could be) brown (+) and white/Brown (-)

Unfortunately, I didn't have the time to pull the harness out under the dash to verify.

Sweet! Thank you!

I ordered some RF R165X3 to replace the rears, and will test one out in replacement of the fronts. I'll see how to new speakers go, and if I'm not satisfied, I'll go ahead and add in the sub. I like bass, but sometimes my 12" Alpine Type R is just too much.
