Troubleshooting my system need some opinions

Hi my names Jeff and ive been having a few problems with my stereo system lately so ill start by telling you what i got. I drive a 2005 Jeep Grand Cherokee with a 4.7L V8 in it and I have a JL Audio 13w7 powered by a JL Audio 1000/1 with a 5 farad tsunami capacitor. I also have an XS Power D6500 for my battery and 0/1 guage wire running to a splitter to 4 guage wire to my capacitor and then to my amp in the back. there's a 100 amp fuse under the hood by the battery and i also put a 100 amp fuse in after the splitter on the 4 guage wire.
I recently purchased the d6500 from mechman.com because I was having low voltage problems and I had an optima yellow top for over 4 years and i've heard they've had their share of problems so when i talked to the guy there he said that changing the battery and doing the big 3 upgrade should solve my voltage drop problems and that my stock 160 amp alternator should power the system fine. So i changed my battery (end of october) and replaced my factory grounds and power wire from the alternator with 0/1 gauge wire and that seemed to fix my problem until about a month ago when everything started going crazy. I would be driving around and when i would go to crank my system it would cut off completly (by completly i mean my head unit would shut right off and my gauges would start acting funny and all my lights in the cluster would flash on and shut back off) but when i would keep the rpms up it would seem to still play so i figured it was my alternator. So i went and bought a new alternator from the local parts store and put that in to see if it would help.
Now whenever I had problems before it would always come up on the amp as low voltage but now it wants to shut my head unit off right away and the amp seems to be working fine. So after i changed my alternator out the problem didnt get any better but i could play it somewhat loud just not where i usually have it and certain songs it would just want to shut my head unit right off. So my next thought was maybe my head unit could be bad. It was an alpine i got about 4 years ago when i originally bought my system, so i went out and bought a new alpine head unit only to have the same problems. So now it got to the point where i couldnt play my radio at all without it going crazy even my air bag light would stay on but i found out it was my clock spring that was messed up and causing my radio to shut right off.
So after i fixed that i figured i had it made and everything would be fine but i went to crank it it still cut off the head unit when i did so now i was really disappointed and decided to completly cut the power to my system in the trunk. So i removed the fuse and shut off all subwoofer controls on my head unit so my system was not getting any signal at all and i cranked it with just the speakers in my jeep and it plays fine no problems the head unit stays on and everything. Ive checked my grounds and cant see anything wrong with them I also adjusted the input sensitivity on my amp because i think that may have been what started it all. I had this system in a 99 Jeep Cherokee first and thats what it was set to but i have the 05 GC now and I have the kicker speaker and amplifier upgrade so that changes the input sensitivity and it was way to high. Whenever i had problems before only my sub would cut off but my speakers would still play and the sub would eventually kick back on now it just cuts everything off radio, speakers and sub and it still makes my rpms go crazy and the air bag light will flash on and go off so i really dont want it to mess up another clock spring.
So my next thought is maybe there is something wrong in the radios wiring harness. I have the PAC C2R-CHY4 harness and ive had it for about 2 years now. I think its this because I have the steering wheel controls but theyre not hooked up because you need another adapter and this radio harness must tie into it somehow and the steering wheel controls are tied into the clock spring as well as the cruise control. So at the moment i have the system disconnected and everything else works fine but id really like to get the sub working again like it should so im hoping maybe one of you guys have had this problem or have heard of anything like it. I really think its a relay or something stupid but i really appreciate it if you read all of this and can give me any input


Thanks,
Jeff
