Good news I got it working perfectly!
The problem was the AV pinout I got from gamesx was not even close to correct. (possibly due to my xbox being v1.6) I went in and used my multimeter to check continuity between the connector pins and the red and white RCA jacks. I used a common ground for both even though Im sure there isnt. Anyway my project came out good. I guess Ill write a quick tut. Tested on xbox version 1.6.
First disassemble your box down to the motherboard, remove the motherboard, flip it over and locate the pins for the AV jack at the rear.
These pins connect to the RCA jacks.
I dont know which is left or right, so you will have to figure that out. Now solder about 10 inches of 30 guage wire to each pin.
Then run those wires through the whole nearest the AV jack and place the motherboard back into the box.
I suggest reassebling all of your boxes components now. If you dont already have LEDs installed around your clear jewel, you should also do that now. The setup of your lm386 chip will be different depending on the number of leds you use but the wiring will still be the same.
Use this as your guide:
In my setup I connected 5V from the hard drive straight to the voltage supply pin and same with ground. The negative lead of your LEDs must also go to the ground pin. The positive LED lead goes to the output pin and finally the negative audio wire that you created earlier goes to input- and one of the signal wires goes to the input+. With no resistors and hooked up to the 5v supply, I had a max output of about 2.5V while playing an average song. So unless you play high frequency music you will not get an output voltage anywhere close to the supply voltage.
