Hello all , Just picked up a 2010 H3 two weeks ago, and i love everything but the sound system (Base model), Has anyone been able to add the factory sub and amp ? i am keeping the single disc head unit for now. My biggest concern is with the wiring harness as i don't believe when i pop off that left inner quarter trim panel that they'll be connectors just hanging there making the job easy. I have the correct panel, sub and amp with all hardware and speakers, just unsure of the harness, if the connectors are not there does anyone sells something i can use?

Thanks for the help
