Google the "big three" upgrade and click the first link to get directions on how. You will ne 0ga or bigger for the big 3 upgrade. especially with the 200+ amp alt. or http://www.the12volt.com/installbay/forum_posts.asp~TID~73496~PN~1 this goes right to it. |

Bronze Member Username: 2000celicaRoanoke, VA U.s. Post Number: 22 Registered: Jan-08 | ok guys i found some info on alternator amps vs. current draw. if i'm wrong here let me know. so far i have a 1500 watt, 500 rms 4 channel amp. current draw should be 23.2. i want to get a 1000 rms mono amp. current draw on that should be 46.3. if i got a 170 amp alternator its able current would be 68. total draw would be 69.5, 1.5 over available current. would this 1.5 matter at all and are my calculations correct? |
