ok heres the deal, it all started this mourning, whenever I am driving at about 2,000 rpm and I hit the brakes, my cdplayer shuts off and comes back on. Plus whenever I brake my cd player face dims and aftermarket gauges dim as well. My power lock didn't work either. Then a few hours later my power lock worked again. I only have 600watts and the battery is half a year old at the max. Alternator trouble?!?!? I have no idea plz help.
