I'm wanting better juice in idle to power the lamps and stereo better. *Keep in mind, my stereo is nothing special(400w amp and a CVR12).
An aftermarket like a mean green will give more juice at idle. Some companies, like HO alt and Ohio Generators (IIRC) can build application specific alts as well. However, to power a 400w amp (pulling less than a continuous 60a max) and the fact that you've swapped over to HID's means that you probably dont need an application built HO alt (or an aftermarket HO alt at all). For your application, whatever is cheaper or easier. An explorer alt would need some bracket fabrication, but if you're handy with that sort of stuff then it's no big deal. An aftermarket alt would bolt right up but likely cost hundreds more.
My good ole' 95a + Yellow Top + Big 3 drops to 12.5v at idle and 13v at cruising speed when I am pushing the system hard (probably 3-4 times more current than your system). When driving down the highway the dimming is noticeable but I try not to damage my hearing too often so it doesn't bother me too much. haha Of course, the more you max your alternator out the quicker it will go out. I remedied the possibility of this problem happening again by getting a life time warranty on mine for an extra $20 at Advance. Keeping a steady voltage will also help with the longevity of the electronics in your truck. I dont know whether or not this is something you really need to worry about.
Now if you're wanting to run a winch, stereo, and off road lights all at the same time I'd highly recommend getting an HO alt built for making power at idle.
