No midrange for sound


New Member
I have a 2017 Kia Forte, and I wasn't happy with the factory sound, was all high-end for me, so I decided to have some better sound equipment installed. Had some Kicker speakers installed in the front doors, an amp, and a 10" JL sub. I'm still not getting any midrange, even after having the people tweak it, and I'm trying to figure out if somehing's wrong with the speaker/amp installation, or if just the head unit on the car is what's causing the problem.

Has anybody had issues with the sound from the factory stereo on good speakers and an amp? The low and high are great, but I can't get any midrange, it sounds so hollow. I'd appreciate any thoughts.
