Hello! I purchased and installed a Pioneer aftermarket stereo for my 2012 with the base stereo. I am using the Pioneer with the factory amps. Once I got it hooked up I found that, even when turned all the way up, the volume coming from the speakers is not loud enough. I reconnected the factory radio and found that it gets plenty loud. Is there some setting (gain control?) on the factory Honda amps that can be adjusted? This is puzzling to me because the aftermarket Pioneer works, it's just not loud enough.
