Kicker Hideaway HS10 Protect mode

Hey Everyone! Installing a Kicker Hideaway in my 2024 GMC Sierra SLT with Bose. I’m running into an issue where the amp goes directly into protect mode. It’s a brand new sub and I also tried another brand new Kicker Hideaway and it was the same issue. Used a DMM and am getting 12.5v of power. Checked the ground and it’s at 0 ohms. The ground is sanded and used with a terminal. I had the speaker level input connected to the sub output first based on some forums I read about and then changed it to the front left speaker. Have done a lot of troubleshooting but can’t figure out why the amp goes directly into protect mode. I have checked all fuses as well and everything is good on that end. The only other thing that I can think of is that I have joined the left and right speaker wires together (two positives connected to one positive and two negatives connected to one negative) that could cause it but I don’t believe that would cause this. At first I was thinking maybe because I’m not using a remote wire and it’s because of the signal sense but after installing a remote wire I get no lights. So I switched back to DC mode. Does anybody have any idea what this could be? Thanks!
