The only thing I changed from the original instructions was soldering the connections together instead of using crimp connectors. I know the crimps are a lot easier, but if you're going to do ANY kind of remotely serious work on car stereos -- you *really* should invest in a butane powered soldering iron and solder all of the connections. I just wrap them in electrical tape after that to insulate them.

I've had so many times now where a crimp connection started failing on me, causing something to malfunction or a speaker to cut in and out randomly -- and the hassle of pulling everything back out to track it down isn't worth it.

I'm not even that good at soldering, but soldering a wire to another wire, or a wire to the end of a single component like one of these capacitors is the easiest type of soldering to do. You don't have to really worry about heating something up too much and damaging it like you do when working with small components on circuit boards.
