Ok so to my noob understand 1 amp is eqaul to 100 watts.

But I see ppl in the "you system" thread that have 200A alts running a 3K watt amp. How does that work???

Like what's the max watt amp I could use on a 180A alt with a deep cycle battery? I'm guessing 2500-2800 watts on a 180A alt from the setups I see ppl running now. Explain.

personally id say 2300 watts daily but others would probably say 2500 is fine

This came from MCA Tech.The 4KW draws just over 400 amps at 1 ohm (full output)....the MCA3004 draws close to 50 amps with full output (all channels driven)...and the MCD1500 draws very close to 150 amps at 2 ohms (full output).
Thanks,

well the saz can pull up to 160A plus the comp amp. ~30-40A plus all of the cars electronics.
so at full output you're looking at well over 200A of current. Now hopefully you won't go around blasting the system 24/7 so you need to be VERY responsible with the system. you won't have the 180A at idle so keep that in mind as well.

Just be very careful

if you didnt order the alternator yet look for one with a higher idle amperage at least... and a bigger alt than 180 if you can afford/find it

P=V*I
P is power in watts. V is voltage. I is current in amperes.
