Good morning. I need some help from you experts. I replaced the original speakers in my kick panels and sound/roll bar with 6.5” kicker 300w 4ohm speakers on Christmas Day. I hear no difference whatsoever. May even sound worse. I installed with polyfill, wire connectors and speaker brackets. My Jeep has the I’m guessing regular radio in it. It has am/fm, sat, Uconnect and CD player. I read on hear that people that changed out those speakers that it made a difference. Did I do something wrong or is it the stock radio. I would appreciate any advice. Thanks and good day.
