I have an 2001 Oldsmobile Alero with a stock battery and 105 amp alternator powering my 1000 rms(at least) amp/sub. My headlights are dimming slightly when ever i crank it up pretty good. I really don't want to throw more money into this system. Are my battery and alternator going to be ok? Thanks in advance.
