Amp question.

[Tlowry_7]

Hello, I have a 2019 gmc sierra 1500 new body style with the factory Bose system. I’m in the process of building a box for under my rear seat to hold 4- sundown audio X-8 v4's. I have a SIA-5000 amp to power those. I also want to add a rear glass sound wall or “stunt wall” and am looking at using 6- Sundown audio Vex-8’s. I’m trying to figure out what amp will work for these. I’m keeping the factory Bose system, and am waiting on an integration harness and then I’m assuming I need a LC2i pro or LC5i pro to pair with this. Thanks!
