I did fix the rear subs, tested and remounted them.. much better bass in the cab now... My tweeters tested good, but neither is working..I was worried the floor amp had bad tweeter outs, but I read that they are (wiring) paralleled to the door speakers, and those were good (didnt have to repair the surrounds either) but I'm wondering if the connections are corroded and where the Tweeters "tap" into the Mid bass door speaker circuits as the wiring from the tweeter appears to migrate from an independent path (until it disappears in a neatly bound group of wiring.. In the doors or under the passenger floor(?)
