I remember a mate of mine had an old Nova SR (which had an amp metre / battery level guage in the dash) with a HUGE amp and sub in the boot.

When the turned the bass too much up the amp / battery guage did a merry dance and the lights on the dash etc all went dim / flickered too. That was down to his alternator not supplying enough juice to the battery.

So, yes, I'd suspect the alternator and get it checked out as said above.
