[QUOTE="Umbra, post: 8462436, member: 658055"] Welcome. Those amperage numbers sound plausible. Whether or not it will power your system depends on what the system consists of. I believe the SA series is rated at a conservative 600W RMS, but people regularly put 1K+ on it. Obviously you'll need an amp to power it. That will account for the largest draw from your alt by far. If you have an amp for your speakers add that too. A 120A alt should run enough amp for that sub. Wire it well and duo the big three upgrade under the hood. I was able to do older 1000W on a 90A alt with very minimal voltage drop only on the hardest notes at full tilt with Big three, no extra battery. Do you have an amp already?
