Has anyone upgraded their front and rear door speakers on their 3rd gen Acura mdx? I called Crutchfied and they couldn’t help because they haven’t worked on that vehicle. Has anyone checked if the Metra 72-7800 Speaker Connector Harnesses works on the 2014 mdx? What speakers do people recommend without an amp upgrade? Should I run rear Co-axial and front Components at 2 ohms or Co-axial front and rear and 2ohms? Does anyone have the specs on the factory speakers, tweeters, and sub?
