Big 3. Battery. Alt. In that order. Until dimming stops.

Doesn't have to be the same size. Just run you power wire from your front batt. to the pos. terminal on the second battery, ground the second battery, come off of the pos. terminal on the second battery to your amp/amps.

will the alt charge up both of the batteries then?

I would try to upgrade your stock battery. and do the big 3 since it is fairly cheap. But it also depends on how much power you are planning to upgrade to.

I have a D5100 PM battery for sale for $141 that would go right in there, or you could add a D1200 to the back. Just wire it in the amp wire, it takes five minutes.
