  1. What wire kit do you have for your Northstar SMSAGM480 or what size wires did you use?
  2. I have a Interstate MTP 78DT battery, I don't know the Ah rating. Is the battery you have a secondary battery?
  3. I used the app and this is what the output is. So what secondary battery has this amount of Ah?
  4. I have a 2004 GMC DENALI XL 6.0 and I'm installing 2 sets of JL Audio Zr650csi one set I will add a JL Audio C5-400cm, a set of JL Audio C2-350X, and a Alpine R-W10D4 sub woofer. I will be using Rockford T800-4ad, T600.4, R150X2, and T1000.1BD to power all my speakers. If my calculations are right the amps should be putting out 2100 watts. My question is do I need to add a high output alternator if so what size? Do I need to add a secondary battery if so what size?
