Strange occurances that seem to be related to my battery - DIYMA.com

It started one time last week when I was driving with my music on on the highway. I went to put my flasher on and the instant I did so the power seemed to turn completely off for a split second and then come back on. I even saw the warning light on the dashboard flicker during that split second. That only happened once.

But 3 times now I have turned on my car to discover that my head unit's setting had been reset as if I had recently disconnected the battery.

I am currently running a front set of components that until yesterday was being fed up to 75W RMS X 2. Now I am giving it up to 50W RMS per channel. This is in addition to a sub that is being fed up to 400W RMS.

I also notice my lights flicker when the bass is pumping. Don't know if that is related to the strange battery activity.

Could it be that my battery is dying?
