Well, no offense but that is a big ol' jumble of mix and match hardware. Looks like a mixture of passive and active systems. No idea why the black AudioControl box is in there, I'm guessing it's something along the lines of an Epicenter box which I never saw the point of. Kind of answered my question about the door speakers though as I'm assuming that those old passive MB Quart crossovers are for the door speakers. (Assuming this because that's the brand on the tweeters.) Probably still works fine, but those definitely aren't going to be working to their full potential now that the drivers are improperly sized. Passive crossovers are great when you use them for what they're designed for, my red truck is a mostly passive system. However, there's no adjusting them to work with anything else. Also if there's more speakers in different sizes then I have no idea how you're splitting the frequencies up properly unless they all have their own passive crossovers as well. (I'm assuming the white AudioControl active crossover is hooked to the sub amp but I could be totally wrong on this.) Regardless, thanks for posting. I'm always interested in checking out other people's audio setups!
