2016 Silverado BOSE sub replacement upgrade wiring

[Rayclark]

I have a 2016 Silverado High Country with the Bose system in it. I’m looking at getting one of these sub amp Kits to replace the factory subwoofer in the center console.

One of the questions I have is , can I just use the existing wires connected to factory sub and connect them to the high level input on the new amp that is included in the kit. Or is that not the best way to do it ? I’m asking because I have seen references to using a custom Bose  Amp T-Harness and then connecting that to a line converter like LC2i.

 

See attached pic of the wires I am referring to.

 

 

Any input would be appreciated

I just replaced my radio, and added a 4channel amp. I have a 15 hc 2500. For me with the amp bypass harness the sub was gray, gray/black. Will try and get the truck side colors for u tomorrow. I toned out the speakers with a battery.

I'm also curious

To add the sub its not hard. You need a lci2 to convert the speaker leads to rca, only if your sub does not have speaker line inputs. On the passenger front fender by the firewall is a grommet for wires to run through. I grabbed a ground under one of the seat bolts.

So the only thing I actually need would be the T-harness like the one that LLJ Customs sells ?   If that's the case, that is awesome. Wont be hard at all.   

 

Just another question ...I can't go full out right now and I've read that it's not advisable to just upgrade the main speakers and use the bose amp. So I was planning on keeping the Bose amp and the main speakers, but was thinking of starting with upgrading the sub and adding an amp for for it. So am  I wasting my time and money right now by only replacing the factory Bose sub?  Will I hear much improvement ?  

 

Thanks again for any input
