okay, it looks like spaceboy was right:
i got my ipod to power the speakers on 2 channels with no HU. I havent gotten the equalizer wired up yet beucase i dont know how to wire the remote turn on to a power antenna out wince i ditched my HU, but once i get that out of the way, i dont see any reason it wont work on all the channels. The sound was very loud, and was good quality up untill the very loudest when it started getting distorted/hurting my ears. Keep in mind i was only running it on 2 channels.
I did it by tapping a switched fuse with ain in-line fuse tap from radio shack, running that through a switch (so i can avoid the turn on thump) and then tapping that into my switched 12V on the radio harness. I then tapped the line outs for all 4 channels and the common ground. I got a little phono-to-solder freindly board from radio shack and wired + and - from each phono, so when those were wired into the line outs and the i-pod was plugged into the board, voila.
i know this is a bit confusing, esp if you havent seen the back of your radio, but let me know if you have questions.
