    120 amp alt

    so after research, it appears that my Jeep has a 120 amp alt... what's the biggest size amp you can run safely through this power? i have two D4 subs and may be in the market for a better amp. thanks

    NOTE: i do not have big 3 or any other electrical upgrades

    if i DID do the Big 3, how significant of a change would that be on my electrical? maybe 1500 watts max?

    Re: 120 amp alt

    Well assume your vehicle is using around 40A worth of power so that's 80A you can use towards your system. 80A * 14.4v = 1152w. Now say your amp is 70% efficient so multiply by .7 and you get ~800w of continuous power before your alt can't keep up. So yeah, roughly 100w per 10A of alternator power
