well you probably dont need a new alternator for amps unless you plan on something crazy, im runnin 250 watts now with absolutely NO voltage drop or dimming. i wouldnt replace the alternator unless you really do need it. but with that other stuff you may need too
I'd always want a bigger alternator for an off-road vehicle. Run lots of lights, winches, power inverters for air compressors to air up after you aired down, Booster E Fans when you're working the motor hard but not getting a lot of air circulation since your really not moving fast as if driving down the highway, AND THEN of course you have the sound system to consider. All serious off-road vehicles need the Big 3 and a bigger alternator and even a dual battery set up if available. You break one night out on some country trail, you might use up all your power in work lights just trying to patch up to get out and back on the main road.
