Thank you. Looking at the description and photos online at GM... couple things stand out when comparing to the video and the installation guide.
1 - 200-watt powered Kicker® subwoofer with quick-connect wire harness to easily secure or remove when needing more cargo room: Does this really come out easily? Looks like it bolts in.
2 - Plug and play, no wire cutting or vehicle modifications . Instructions show cutting the carpet, running wires to dash, and splicing them. Does that occur or does it plug into an existing socket under the back seat?
3 - DSP Tuned Specifically to your Next Generation Silverado 1500 Crew Cab and Extended Cab. Photo shows a DSP module, but the instructions don't mention it. Looks to be mounted behind the back seat?
BTW - nice that the price dropped $150 recently.
