Depending on whether or not you guys agree that is. I've been trying to figure out how to wire up the 5x7's in my system for the last couple of weeks. All I've had since I bought the car was the tweeters. Nothing else has worked. I finally picked up the right harness today from Walmart. Wired it up and plugged it in and nothing works. So I'm looking and I'm trying to figure out why I have two identical power plugs. I would think I only need one. So what I'm thinking is that that PO installed the Mach 460 components, but never hooked it up right. Is it really that easy to put in a Mach 460? All the wiring seems to be there. There just isn't any power going to the plug that seems to be for the Mach. I'll snap a couple pics so you guys can see what I'm talking about.
