GM Kicker Subwoofer part 19418148. Should fit 2017 + Colorado and Canyons BUT...verify your truck first. This is the kit with the amp for the sub under the box. Super easy install. I had it on my non-Bose system and it gave me what I needed. New in August. Local only

* I am heading to Vegas in about 2 weeks and could potentially bring it along the CO, UT, NV I70 route...with a small deposit.
