is this alternator big enough

[SouthPole1989 0]

hi, i currently have a 200 amp alternator ( excessive amperage) but i have had a problem. it came with a 2" overdrive pulley and i need a shorter Serpretain belt for it and they don't make one short enough. so i have to go with a 160 Amp alternator because of the Serpretain belt problem. the amps i have/ going to be using are: Us amps md1d @1 ohm (1200 underrated watts) and Jl Audio 450/4 because of the RIP Power supply. Would a 160 Amp alternator be big enough for roughly around 1650 rms watts? and i am going to get a Yellow top Battery under the hood.

i ran ~2000W on a 90amp alt and chitty battery, got voltage drop to 11.5 on burps. If your'e going for SPL you'll want to keep your voltage up as much as possible though

it's a 96 saturn sl2. ok so a 160 plus a deep cycle battery should be good to go? i don't totally care to much about the bass being to soft but i care mostly about how the speakers because one i sometimes turn off my subs and just listen to speakers. thats the main reason for the jl 450/4. i just mostly want a dd that can sound good and subs that can hit pretty nicely. I am going to use RE se 12" for the subs.

For that amount, I think you should be ok, do a Big3 also.
