I recently changed out the factory speakers in my 2019 Ram Bighorn with 8.4" display and standard 6 speaker configuration. I installed Infinity Reference REF-9633IX 6x9 3-Way Coaxial Speakers (300 WATTS 100 RMS) in both front and rear doors and used the Metra 72-6514 Speaker Harness for the connections. The speakers sound great but now I have droning noise that is intermittent while driving. The speakers with the harnesses should be a simple plug and play. Speakers are called out on Crutchfield website as a fit for my truck and the Metra 72-6514 harnesses are the recommended harnesses for install. I have to install the tweeters as the factory ones are still in the truck. I am wondering if when I install matching tweeters will that make a difference. I understand the tweeters and the front door speakers are on the same wiring. Any ideas on what is going on or suggestions would be greatly appreciated. Thank you.
