Right now I have coaxial Polk Audio db651s in all four doors of my 2011 jeep liberty powered with 50W a piece from a Rockford Fosgate amp and Rockford Fosgate Prime R1T-S tweeters in the dash reflecting off of the windshield powered with 50W a piece from my head unit. The tweeters are only rated for 40W RMS and get distorted bad at 2/3 volume or higher. My question is would it be better to just replace the tweeters with an appropriate replacement such as the RE Audio TW-25 Tweeters and keep my coaxial door speakers or replace my front door speakers and dash tweeters with the polk audio 6501 component set and power those from only my amp?
