I am in the process of swapping out my speakers in my 2020 Sierra with the 7” IOR stereo. Did Kenwood 6x9 and 2.75” in the front and Rockford 6.5 in the rear. Sound is ok but I want to add an amp to bring it to life. I called the install bay to get an amp recommendation and he said because of the crossovers in these new models I need a module to get proper signal for the hi level input or it won’t help. It’s like $800! Anyone have any advice? I’d like to just do a hi level input and amplify these bad boys! Cheers!
