I'm gonna gain down to where I'm only drawing ~3500-4000. With the alternator and a couple batts, I'm not seeing much voltage drop in my near future.

unless your batts rest at 14volts or you have a 300amp alternator you will be seeing voltage drops.... even at 3500-4000rms. Remember, amps run most efficiently when they are running near full capacity.
