Newbie to the forum here!!
I have a 99 Tahoe with stock alternator and Optima Red Top 9004-003 Battery. The system I plan on running is an 800 RMS amp and a 2500 RMS amp with 2 8" cooling fans. I have also have the Pioneer AVIC-Z150BH head unit. My question is if my current alternator and battery set up is sufficient enough or if i need to upgrade either of them. I have already done the big three upgrade as well. Thank you in advanced for you help.
