altenator question

i have a 96 4.o and i think the stock altenator is 117 amp.
i have one optima yellow top and i want to put in a second for the stereo since i have alot of lights comin my way...i will have an isolator so the second battery will only charge when the vhicle is running and will not discharge when it is off...will this altenator be enough temporarily like for the summer or will i need a bigger one right away? also do the limiteds have bigger altenators cause i dont want to pay alot of money for a stinger.
my other option is there is place by me that till rewind my altenator but im not sure how expensive it will guessing no more than 200, so if thats the case what should i rewind it to? i think the batterys are 600 cold crankin amps but like 85 continious or somtihing, so should i do double the batterys like 190 amp altenator or what? there was a guy that i met through ebay that had 160 amp altenators that weere chargin 85 amps at idle but i lost his addy. should i just go to the place and tell them thats what i want ? my main battery has all stock power, plus a h.i.d. (real conversion) kit for headlights, plus im planning on at least 4 pairs of drivving lamps about 85 watts. and a pair of loading lights as well as secondary reverse lights, at about 55 watts. so the most i can do i s 4 pairs of driving lamps, the hid's and the stereo blasting all at once, but the second battery is strictly for the stero.
any info will be helpful
thanx in advance
