I have a 00 Cherokee, and the system goes front tweeters, driver door 6x9 and 2nd row 6 1/2 ... With only front and rear options on fader, that would have me wiring my tweeters with my 6x9s ... Maybe I'm over thinking it but when I set my cover will it throw things off wiring two opposite speaker types to the same channel? And a 6 1/2 is a better option? What are some ideas or what do seasoned veterans do?
