    Going with my new engine build, I am going with a 160 amp motorcraft alternator. Here is the system that is going in.

    Alpine IVA-w910
    Alpine PDX-F4 100x4 (rms)
    Alpine PDX-17REF
    JL 12v3w3
    JL JX500/1 (rms)

    Using a calculator, I am figuring somewhere between 80-88 amps draw. I am thinking it is going to be close, but I dont want the flickering light syndrome. Will this be enough....or should I start looking for a bigger alternator.

    Do not buy a capacitor. Your stock electrical will be fine with the setup you posted. Stay away from caps.
