I've been noticing that my lights will dim for a split second then go back to normal, it's not a flicker they just dim every so slightly. It just started happening recently. Am I drawing too much power from the battery (I have 2 gauges, 7" touchscreen, an amp and a 10" sub. I do keep the sub on the lowest possible setting at all times, I only have it because when I "upgraded to a shaker500 a few years ago I lost all my bass, now that shaker is gone and I've got a avhp4300dvd.)

The connections to the battery are all good. Is this a sign of my battery going bad or could it be something else?

You have overloaded the OEM charging/battery system.
The water is being drained from the bucket (battery)
before the pump (alternator) can fill it back up.
Get a bigger pump (alternator) with some real amps
at idle and some monster amps at higher RPMs.

The stand-by current draw from a sub amp can
be a big drain even not at its loudest setting.
Very inefficient at low levels. Most goes up in
the form of heat.

You can try a bigger bucket 9battery0 but your
pump will soon fail trying keep it filled.

You put too many extra holes in the bucket without
upgrading the pump. The OEM pump does very little at idle.
