h.o. alternator without the draw, is it ok?

I recharged my battery and it is running fine at the moment but I have a belt sqeeul or alternator sqeeul. Its the pain in the *** to adjust the belts and has been realy cold here. I am not going to buy an alternator when I have a perfectly good one on the shelf that is H.O. output. My question is if my alt craps out before I get my 1700 watt system in will there be any problems running this 170 amp alty? I would ofcourse increase the big 3 as far as engine and battery grounds and positives. The car is a '91 honda prelude with a stock 70 amp alt. The H.O. Alt is 170 amp with lifetime warranty. I have a hawker oddyssey pcmjtL1200 that I would put in aswell and if needed I could probably get my trunk/amp battery in too that is a hawker oddyssey pcmjt1700. My first priority is to get this alt and batteries in because I know my battery is on its last leg as it turns 6 years old this month. It is a die hard gold I believe.
