i would say most of your problems are from

B1327 - Vehicle system voltage below 9.0 volts

that would indicate dying battery and throw pretty much most of them codes

Hmmm, to be honost i think i have a really really good battery, but that less then 9V could of happend when i was playing my music in my car one day for around 30 mins, and keep in mind i have a 1000W stereo in my car, with a double din headunit/GPS and subwoofers and 2 amps. So i kinda doubt thats the cause if what im mentioning seems reasonable, also my car idles 14.8V with stereo full blast and only .4V drop when bass hits hard.

I've always wondered if some of my problems were related to a bad alternator or battery. I CONSTANTLY get a AMP U1000 code, my 2000 DTS idles at 14ish volts but drops easily in the 11-12 volt range when my bass hits. I have a 1200.1 momo-block Kicker amp and 2 12" Kicker L7's.

wow thats a preety big drop ... buy yea my car has dropped 2 12V if i let the car sit on idle for a while but i soon a i push the pedal down a centimeter i get all the power from the alt bring my voltage to a nice 13.5 - 14.8 volts. And the highest i ever got was 15.2 which was right wen i started the car ... i wonder why my voltage is always at 15V when i start it in the morning in the -18 Celcius canadian weather.

was the system put in professionally or rigged in there because that could be killing the battery and causing all them codes to appear

Holy Crap thats quiet alot anyway was the battery ever changed to compensate for the extra power draw also try clearing all the codes and try to drive for a little while without the system running and check to see if any of them come back

Yeah, $5500 seems extreme for a 1000w system. You must've paid retail prices for your equipment instead of dealer or online discounted prices. If they charged you $1500 for the headunit/GPS, $1000 for the 2 amps, $1000 for the subs, and depending on if you replaced all your coaxials and with labor, that could very well be $5500, but the total wattage would have to be over 1000w.

I just re-did my whole system last week and it cost me $3200, but I'm at about 7000 watts. I'm using a Kinetik KHC-2400 as my secondary battery to power the system, and I also have a high-output alternator (about 220 amps). I highly recommend an alternator upgrade, UNKUT. If your bass was to hit hard enough, it could short circuit your car.
