yeah, you're definitely going to want to look into a new alternator. AT LEAST 200 amp high output alternator. Any amp that you choose...upwards of 2000watts rms will draw MASS current. so, i'd first make sure you have enough money to get a new alternator...get it re-wire and installed...and also think about a redtop under the hood for and and the possibility of a yellow top in the rear. peace
