What Size Alternator Would I Need To Run A 1500 RMS Amp?

Question

Im installing 3 jbl 10's that run a 400 rms x 3 (1200). I want to run them on a jbl gto14001 which is 1500 rms. I wanted to know how many amps should my alternator be in order to run the amp and the rest off the electronic in mi car (in dash monitor,a/c etc).

Answer 1

at least 125 to do the job. but if you still feel it pulling the charging system down. a bigger alt plus the big 3 in needed. also look into powercells like kinetik or bat cap.
