so i bought a beat-to-hell XJ a while back as a trail rig, and it came with one of these stereos. i dont know if it works or anything, i just pulled it out today, but if anyone knows anything about this thing (as in "it sucks lead paint chips" or "its so sweet that it get the shakes every time i look at it") or can decipher this, it would be much appreciated. if this thing works, i want to put it in my yukon, and run the 4 door speakers and a 10" or two in the back. how would i go about wiring this thing? thanks yall.
