Tweeter. It's an audio shop here in Houston. All you have to do is go to an audio shop ask for 4 guage Monster Audio ground cable. You can also use Rockford Fosgate, Stinger, or Lightning Audio ground/power cables for amps. This is type of cable that you would want to use to make a ground kit. If you want, you can go for thinner 8 gauge cables. Quite honestly, I wish I had used 8 guage as it would have been adequate enough to do the job, and it would have been a hell of a lot easier to bend around all of the tight parts of the engine bay.

For the connectors, you can get the expensive gold ones, or regular ones for cheap. I picked up 12 for $5, and when I ran out, I went back, and they gave me 6 more for free

If you want to put them together, just crimp them. However, if you are going to make a good wire, you will need to solder them too, not just crimp. A regular soldering iron won't cut it, so you will need a propane/butane torch to melt the solder hot enough so that it will properly cover the top part of the connector terminal:



I used a $15 propane torch from ACE hardware. I put the heat shrink on with a hairdryer.

Tommorrow I'll post pics of how I managed to put a tight crimp on the terminals. It involved using a dremel to cut away the center so that it will close in tighter.

As for the ground points, I'm still unclear about the alternator. I've located a good ground point for the throttle body. I already have a wire running to the cylinder head next to the upper radiator hose, but I may be adding another to the long bolt that goes thru the valve cover and deep into the cylinder head.
