Why?'s Audio Adventure

[why?]

So I decided to start my own thread, seeing as I'm lazy as hell and I haven't done anything.

So let's start at the beginning. I suck at using my hands doing stuff, generally it ends up in trips to the hospital. But I am learning and slowly figuring out how not kill myself.

I want to learn how to do car audio stuff. I am worried about adding too much weight, and of course blowing my car up, so I am going to go slow and make sure I do it right.

I am not going to add insulation, or anything of the like. I probably am going to strip my car even more, and maybe completely like mr_milessee build thread.

Definitely on the sq side. I had an old (early 90's probably) JL 10" sub in my car for a few years, it was all of 150 watts, yet it gave me a headache if I played it too long. I never really turned it up very loud either.

Now after listening to Derick's car, I know what can be done. His build is awesome, but for me, I need more surround sound. Something needs to be in the back for me to be completely happy.

And at first I am going to aim for a budget type build, figuring If I screw up I won't cost myself too much money. Although I might as well get the right wiring for a full on great build. I don't see the point in having to do that too many times.

I've been in and out of audio quite a bit over the years, but never to the point of actually doing anything. I know some stuff, and some brands, and the like, but only knowing, with zero experience actually doing.

As for music I listen to, well everything. Queen, Keane, 3rd wave ska, metal, show tunes, etc.

So from browsing, the big 3 comes up repeatedly. Yet definitions of what it exactly is seem to be next to impossible to find on the net. What is it specifically, how should I do it on my Yaris, and what wires should I use with my goals?
