I have a 90 amp factory alt and I'm wondering if I need a new one due to what I'm installing?


I have a kicker ZX1500 and I'm going to buy a RE audo 15'' SX


Dominick Iraggi quoted me on a new one made by him at $419 for 220.


I'm thinking maybe I could just add another battery. I just bought a Stinger SPV44 battery. Maybe this battey with the stock battery and a bat isolator by stinger?
