Time to start modding: Want to add subs to existing BOSE system step in
 

Well I stepped into a 17' 2SS w/ a BLOSE system and like my C7 I feel it can use just a little more bottom end. It actually sounds much better then the BOSE systems I had in my C5's but I do tend to like some deep bass. Anyways I was super excited to see everything is in the trunk in regards to power, factory amp, etc...I added the JL 2 10" Corvette specific to my C7 and it was a piece of cake. Same setup. Only thing I had to run up front was the remote bass knob. In any case It looks like this project is going to be $650. Heres the shopping cart and questions:
Ebay
6th gen specific 2 12" box
2 12" Fosgate P2D4 subs
Fosgate 1000 watt monoblock
4ga amp kit

And this T harness or breakout

Is this harness worth it. Seems a bit pricey. Are there less expensive options?

Nope as Steve has spent lots of time and money doing these harness. If your only looking to add a sub this would be the lowest cost I think, but understand it's not the best or lowest bass you can get using this harness.
If you wanted a much better SQ then add the NAV 650 GM about $850 or the new AmpPRO $420 this will provide the cleanest SQ possible from the head unit.

But that would also need a 2nd 4 channel amp and DSP like the JL Twk D8.

Thanks Christopher. Finishing up the lowering springs now and going to start on the system later today. Should be rather quick. The amp I bought doesn't have hi pass inputs so I ordered a cheap pac line converter. I will just connect it to this harness and that should provide me with my RCA's. Should be done tonight. LOL

Grab the ANC delete harness too to make the install much easier and faster

ANC delete harness + T harness + Pac Line converter... where is the face palm emoji?

Just get the Ampro, get clean sound with a flat signal, don't need ANC delete harness, or the rest of the cheap contraptions people have come up with.
