To replace the amp in the kickpanel you're better off with an idatalink HRN-AR-FO3 harness, as this gives you all the plugs to connect to your cars harness. You have to modify the harness though, but if this isn't intimidating to you i would go this route.I have a 2015 GT Premium with the 9 speaker set up. Is this what I need to add a amp to replace the amp in the kick panel? I want to install new component speakers in the front and install a 2 channel amp to push them. Has anybody done this to their Gt? If so can you give a install tutorial.
