Quick Q:
Is it imperative to disconnect the battery cable?
Last time I did that, the system kinda shorted or something when I reconnected it, for some reason. Or at least it acted very very funny when I attempted to start it up again. As in, it didn't want to do anything at all. And it freaked me out that it was cracklin' and crap when I put it back on the post, but nothing was on in the car.
