I already have a kinetik 1400 which has been using as a starter battery along with powering 800w between 2 amps and has worked pretty well. If i upgraded to about 1400w between 2 amps would it be a better idea to get a dedicated starter battery then throw the kinetik in the back, or would I still be sittin alright with only the 1400 up front? If i need a new starter battery, would i need a deep cycle one or just a starter with a isolator? Should i upgrade my 4 gauge to 0? Thanks for any thoughts!
